Political slogans change every day, but the capital flows that policies create can last for years. This handbook shows how to break the grand narratives in the news into investment themes you can test, bet on and admit you got wrong.
3 yearsThe clean-energy tax credits passed in 2022 were seen as decade-scale industrial policy, yet they were sharply cut back in 2025. A narrative can run for ten years; a policy may last only one Congress.

Introduction
Trade the policy, not the slogan
Political news is the noisiest kind of information in the market. But beneath the noise are things that really change where money flows: budgets, laws, tariffs, export restrictions, subsidies and procurement contracts. This handbook cares only about the latter.
The difference between a slogan and a policy
A politician says, “We're going to bring the factories back.” That's a slogan. Congress passes a law that subsidizes companies building plants at home, the Treasury issues the detailed rules, companies announce investment plans and engineering firms win contracts. That's policy, and the capital flows it creates. The first may be forgotten the next day; the second shows up in earnings reports for years.
Slogan → official statement → law or order → appropriation → actual spending → company revenueThe further right you go, the higher the certainty, and usually the more fully the market has priced it in. Good thematic investors step in at the middle stages: the direction is already clear, but the money hasn't fully reached the income statement yet.
Why set your political views aside
Everyone has political views, and that's normal. The problem is that political views quietly creep into your positions. When the side you support takes office, you tend to believe its policies will all succeed; when the side you oppose takes office, you tend to think the economy is headed for trouble. Both tendencies lead you astray.
The market doesn't care whom you support. It cares only which companies' revenue a policy will raise and which companies' costs it will push up. A useful test: if the side you support loses power, would your positions keep you up at night? If so, you're betting on a belief, not on logic you can test.
Where this handbook's themes come from
In recent years, US policy has settled into several fairly durable themes, and many of them have drawn some degree of support from both parties:
Main theme
The logic behind it
Chapter
Supply-chain security and the Western Hemisphere
Move key industrial supply chains out of regions with high geopolitical risk, to the home country or its neighbors
Chapter 3
Defense and military preparedness
Great-power competition and regional conflicts are pushing countries to raise defense spending for the long term
Chapter 4
Resource and energy independence
Supplies of critical minerals, energy and fuel are treated as a national security issue
Chapter 5
Reshoring and tariffs
Use tariffs, subsidies and procurement preferences to pull manufacturing back home
Chapter 6
AI and power
AI is seen as central to productivity and national competitiveness, driving investment in power and infrastructure
Chapter 7
Inflation, consumers and demographics
Inflation hits income groups differently; population aging creates long-term demand
Chapter 8
Chapters 1 and 2 cover method: how to score a narrative, and deciding first what to avoid. Chapter 9 covers elections and policy cycles, Chapter 10 covers execution in practice, and Chapter 11 is the toolkit.
Before you read
The companies and ETFs mentioned in this handbook are only examples to help explain the themes. They are starting points for research, not recommendations to buy.
Policies change. This handbook describes a framework and the public facts as of writing; check the current status of the relevant laws and budgets before you use it.
Every theme has a counterargument, and the handbook lists it alongside. Looking only at evidence that supports your view is the most common way to lose money in thematic investing.
01
Chapter 1
Scoring narratives: from slogan to cash flow
The narrative decides what you research; valuation decides when you buy. Scoring these two separately is the first step to avoiding “right story, lost money.”
Four steps: from change to price
1
Look for structural change: a trend that will last several years and doesn't depend on any single headline. Ask yourself: over the next few years, where will the world be forced to spend money?
2
Find the unavoidable beneficiaries: the companies everyone has to buy from, no matter who wins the competition—the proverbial sellers of “picks and shovels.”
3
Avoid the most crowded vehicle: the stock everyone is buying has often already priced in years of good news.
4
Wait for the price: a good company is not the same as a good price. Wait for a pullback, for valuation to come back to a reasonable range, for volatility to fall, and then buy in stages.
How long a policy lasts matters more than how strong it is
How much revenue a policy brings an industry depends on how long it lasts. Compare two laws passed in 2022:
CHIPS and Science Act (2022)
Members of both parties voted for it
Its logic, national security and competition with China, is shared by both parties
Largely continued in the years since, with subsidies rolling out
Inflation Reduction Act (2022)
Passed the Senate on a party-line vote
Clean energy tax credits are at its core
The 2025 tax law sharply cut the credits for electric vehicles, wind and solar
This isn't a judgment on which law is better. It illustrates a pattern: a policy backed by only one party is much more likely to be rewritten after a change of government. The stocks of companies that bet on it will swing hard with election results. Directions both parties support, such as defense, supply-chain security and export controls on key technologies, usually last longer.
Six scoring dimensions
The first four measure how reliable the narrative is; the last two measure how attractive the price is. Keeping them separate is the only way to answer two different questions: is it worth researching, and is it worth buying now?
Score a narrative and see which quadrant it lands inFigure 1-1 · Interactive
Policy stage
Political support
Demand duration
Unavoidable beneficiary?
Crowding
Valuation
Narrative durability scores up to 8 points and price attractiveness up to 4. Only durability of 5 or more with price of 3 or more lands in the “build in stages” quadrant. Most hot themes land in the upper right: a great narrative at too high a price, best put on a watchlist to wait.
The narrative can be right and the instrument wrong
Within a real trend, plenty of companies fail through poor execution, competition, debt or dilution. A correct narrative only tells you money will flow in that direction, not that it will flow into the company you bought. A few common mismatches:
You bought the purest story, not the most profitable link. The profits from a new technology often land first with suppliers of equipment, materials and infrastructure, not with the best-known end-product companies.
You bought the concept, not the revenue. A company with a hot word in its name but little related revenue will trade with the theme, but its long-term performance depends on its core business.
You bought a single company and took on single-company risk. One company's accident, lawsuit or management change can wipe out everything the theme earned you. A thematic ETF spreads out this layer of risk.
Write down invalidation conditions
Before you buy into a theme, write down which facts would make you admit the call was wrong. Note that these are facts, not prices:
Bad invalidation conditions
Admit you're wrong if the stock falls 20%
A feeling that the wind has shifted
Good invalidation conditions
The related budget is cut in an appropriations bill
Major customers cut capital expenditure (capex) two quarters in a row
The subsidy rules exclude this company
A narrative is a tool, not a creed.
02
Chapter 2
First decide what to avoid: countries and markets
The first step in thematic investing is often subtraction. Rule out the markets that are structurally disadvantaged or whose risks can't be clearly stated, and the remaining choices get much clearer.
Cheap is not the same as undervalued
Many countries' stock markets trade at low price-to-earnings ratios (P/E) for years and look cheap. But low valuations usually have reasons: slow growth, an old-fashioned industry mix, low returns on capital, unstable policy, a currency that keeps losing value. If those reasons don't change, cheap things can stay cheap, or get cheaper. That's a value trap.
To judge whether a market is really undervalued, ask: are there signs that the reasons it's cheap are changing? For example, corporate governance reform, a shift in the rate environment, or a cyclical turn in its main industries. Without a catalyst like that, a low valuation by itself is not a reason to buy.
Buying a country's index means buying its industry mix
Country indexes are usually market-cap weighted, so a country's stock market performance is largely decided by its few biggest industries:
Market
Rough index makeup
What it's really a bet on
South Korea
Heavy weighting in semiconductors and memory chips
The global memory cycle and tech capital expenditure (capex)
Taiwan
A single leading chip foundry makes up a very large share
Demand for leading-edge chipmaking, plus geopolitical risk
United Kingdom
Heavy in energy, financials, consumer staples and mining
Commodity prices and dividends; very little tech
Germany
Heavy in industrials, autos and chemicals; highly dependent on exports
The global manufacturing cycle, energy costs, foreign trade
Mexico
Consumer, financials and materials, plus nearshore manufacturing
US demand and trade relations with the US
United States
Heavy weighting in big tech companies
The profitability of AI and the platform economy
This table shows that “I'm bullish on country X” is too coarse. Which of its industries are you actually bullish on? If it's that industry, buying a global sector ETF or the industry leaders directly may be cleaner than buying the whole country.
Capital has no nationality
Capital flows to wherever returns are highest and risk is most manageable, whatever the country. So judge a market the way capital does, comparing coolly:
Growth and returns on capital: can companies keep earning returns above their cost of capital?
Currency: for a dollar-based investor, a falling local currency eats directly into stock returns.
Governance and shareholder returns: do companies care about minority shareholders, and do they pay steady dividends and buy back shares?
Policy predictability: could the rules change suddenly, and could foreign investors be treated differently?
Geopolitical and sanctions risk: this used to be widely overlooked. After the Russia–Ukraine war broke out in 2022, Russian stocks held by foreign investors became untradable almost overnight, and the major index providers then removed Russia from their indexes. The holdings were still there, but they could no longer be sold.
Markets that call for extra caution
Type
Why be cautious
If you must take part
Developed markets with long-term low growth and low valuations
May be a value trap; no catalyst
Take part only on clear reform or a cyclical turning point
Highly concentrated markets in a geopolitical hot spot
Rise fast in good times, and fall just as fast once geopolitical risk rises, like a “hot potato”
Small size; treat it as a trade, not a long-term allocation
Markets unfriendly to foreign capital, with high risk of capital controls
However low the valuation, a rule change could leave you unable to get out
Use ETFs with good liquidity; avoid holding local shares directly
“Emerging markets ex-[one country]” portfolios
Removing one big country's risk doesn't make the rest low-risk. Each remaining country has its own currency and political risks
Check the top ten holdings and country weights; don't go by the name alone
The benefit of subtraction
Writing a “do-not-touch list” first protects you when the market gets excited. When some market suddenly surges and everyone on social media is talking about it, just glance at the list: why is it on there? Has that reason changed? If not, let this opportunity pass. Missing an opportunity costs far less than getting trapped in a market whose rules no one can pin down.
From the field
Traders who invest by theme often publish a list of “markets to avoid” before announcing the themes they plan to research. The order itself means something: first rule out the places whose risks can't be pinned down; only what's left is worth your time.

Chapter 3
The Western Hemisphere and supply-chain realignment
For the past thirty years, globalization ran on one principle: “make it wherever it's cheapest.” Now more and more policy asks a different question: where is it safe? The answer is often at home, or in a nearby neighbor with stable relations.
From efficiency first to security first
Supply disruptions during the pandemic, regional conflicts hitting shipping, and export controls on key technologies have made governments reassess supply-chain risk. The new thinking goes by several names:
Reshoring: moving production back home.
Nearshoring: moving to a neighboring country, such as from Asia to Mexico.
Friend-shoring: moving to allies with stable political relations.
The shift already shows up in the data: in 2023, Mexico overtook China as the largest source of US imports. For investors, the key question is: as supply chains reorganize, which pieces must be newly built, and which services must be bought?
The Western Hemisphere gets new attention
US policy debate increasingly treats the Western Hemisphere (North, Central and South America) as America's strategic backyard: both a destination for relocated supply chains and a source of resources and security. This brings a risk that used to get little attention: commercial assets can be redefined as national security assets.
In 2025, the sale of port operating rights at both ends of the Panama Canal was debated in terms of national security and great-power competition. What had been an ordinary commercial asset sale became a diplomatic issue. This means the ownership of strategically located ports, mines, power grids and communications facilities can change suddenly with policy, and the companies holding them may benefit or may be forced to sell.
Three phases: security first, then resources, then manufacturing
The typical order in which capital enters a regionFigure 3-1
Each phase has different beneficiaries and a different pace. Phase one money comes from government budgets: it arrives fast but is limited in size. Phase three money comes from corporate capital expenditure (capex): it arrives slowly but lasts the longest.
The logic of this order is simple: capital won't go where it isn't safe. So when a region becomes a policy priority, the first orders usually go to companies in security, law enforcement and surveillance. Once security improves, investment in resource development follows. Only when both infrastructure and politics have stabilized does long-term investment in manufacturing and logistics arrive at scale.
Types of companies often placed in this chain include drone and maritime equipment makers and government data-analytics software companies (phase one); copper miners and oil services companies (phase two); and industrial real estate, cross-border rail, and engineering and construction (E&C) companies (phase three). The lazy way to invest in Latin America as a whole is a regional ETF, such as a Latin America 40 index fund or a Mexico country ETF.
Mexico: two sides of a coin
The case for
Close to the US, short shipping times
Relatively low labor costs
The North American trade agreement provides a framework
Already the largest source of US imports
The case against
The trade agreement is reviewed periodically, and tariff threats can appear at any time
Crime and security problems weigh on willingness to invest
Infrastructure such as power and water can't keep up
Some investment just assembles Chinese components in Mexico
With a “two-sided narrative” like this, the best approach is to watch the evidence on both sides at once: foreign direct investment (FDI) and vacancy rates in industrial real estate (the case for), and trade agreement reviews, tariff announcements and security incidents (the case against). Shift your position toward whichever side the evidence is piling up on.
Regional politics is changing too
In recent years, some Latin American countries have elected governments that put more weight on markets and attracting foreign investment, while others have stepped up resource nationalism. For investors, a government's place on the political spectrum isn't the point. What matters are a few concrete things: can foreign capital move in and out freely, are contracts and property rights respected, and could resource taxes and royalties be raised suddenly? These decide the value of a mine or a railroad more than election slogans do.

Chapter 4
Defense: wars end, preparing for them doesn't
A conflict ends, but its lessons reshape countries' budgets for the next decade. To invest in the defense theme, separate two kinds of money: emergency spending during a conflict, and military-preparedness spending that continues after the conflict is over.
Why defense spending runs on a long cycle
Europe is catching up: at the 2025 NATO summit, members agreed to raise defense and related spending to 5% of GDP by 2035, including 3.5% for core defense spending. That's far above the under-2% level that used to be common.
Stockpiles need rebuilding: recent conflicts have used up large amounts of munitions and air-defense missiles, and many countries will need years to replenish their stocks.
Bipartisan support: in the US, the defense budget is one of the few spending items both parties are willing to back, so it is durable.
Long procurement cycles: contracts for a warship or a fighter jet often run more than ten years, which gives contractors high revenue visibility.
Modern war needs “cheap, good enough and mass-producible”
Recent conflicts have shown that large numbers of cheap drones and munitions are often more effective than a few expensive platforms. Using a missile that costs millions of dollars to shoot down a drone that costs tens of thousands is economically unsustainable. This has shifted procurement priorities:
Direction
Logic
Types of companies often discussed
Drones and loitering munitions
Cheap, mass-producible, expendable
Makers of small drones and target drones
Munitions and propellants
Used up fastest, short on capacity
Munitions makers, chemical feedstock suppliers
Air defense and counter-drone
Needs cheaper ways to intercept
Sensors, electronic warfare, directed energy
Shipbuilding and repair
Navies are expanding; shipyard capacity is the bottleneck
Military shipyards
Software and data
Battlefield information integration and decision speed
Defense data-analytics software companies
The lazy expression is a US aerospace and defense ETF (for example, ITA or PPA). Be aware that commercial aerospace has a sizable weight in these ETFs, so they are also exposed to the air travel cycle.
The post-war trade: which costs will disappear
During a conflict, the market pays many extra costs for risk: the risk premium in crude, marine insurance premiums, freight costs from rerouting, airlines' fuel costs. When a conflict eases, the most useful questions to ask are: Which costs created by the war will disappear? Who benefits most when they do?
Each stage of a conflict brings a different set of winners and losersFigure 4-1 · Interactive
The example is a regional conflict that affects an oil-producing region and shipping lanes. Real conflicts rarely move through the four stages in order; they often swing back and forth between escalation and standoff, so watch the “confirmation signals,” not the headlines.
One more point is easy to miss: defense stocks don't necessarily fall after a war. If the conflict's lessons drive long-term preparedness spending, defense contractors' orders keep growing; the ones that fall are usually companies that live on emergency spending and short-term orders. So chasing defense stocks at the height of a conflict and panic-selling them when it eases are both common mistakes.
Don't make a conflict your only reason to trade
The timing and outcome of geopolitical events are extremely hard to predict, and the market's reaction to them is often more short-lived than you'd expect. A sounder approach:
Use long-term positions to bet on the structural growth of preparedness spending, not on any one conflict.
Trade a conflict short term with small size and defined-risk instruments (such as spreads), and write your exit conditions in advance.
Hedge within the portfolio: when you hold assets that benefit from escalation, put a small slice of money into assets that benefit from de-escalation, such as airline stocks or call options on them.

Chapter 5
Resource independence: energy, critical minerals and gold
Real industrial independence starts with resource independence. Without copper there's no power grid; without rare earth magnets there are no motors or missiles; without fuel, no amount of crude oil will move a truck.
Critical minerals: the bottleneck is processing, not mining
Many critical minerals aren't scarce on Earth. What's scarce is the capacity to separate, refine and process them after mining. Take rare earths: about 90% of the world's rare earth processing capacity is in China. That makes it a geopolitical tool:
Starting in 2023, materials such as gallium, germanium and graphite were brought under export controls one after another.
In 2025, the controls expanded to several rare earth elements and related technologies, and some overseas automakers and electronics makers faced parts shortages for a time.
Countries have responded by trying to build complete domestic “mine-to-magnet” chains. That takes many years and huge investment, and in the early years it often makes no economic sense, because the competitor's processing costs are lower and it can push prices down. So governments have started stepping in with more direct tools.
Government stakes and price floors
In 2025, the US government did things rarely seen before: the Department of Defense took a stake in a domestic rare earth company and committed to a long-term price floor and purchases; the government also took a stake in a large chipmaker. However you judge this, the investment implication is clear: the government has stepped in behind certain companies and taken on part of their price risk.
A price floor works like a put option the government hands the company for free. Here is a hypothetical example:
A price floor turns a cyclical stock into a business with a safety netFigure 5-1 · Drag to adjust
No floorWith floor
—Profit per kg, no floor
—Profit per kg, with floor
—The floor works like a put worth about
Assumptions: production cost of $70 per kilogram. The put is valued with Black-Scholes using a 1-year term, 40% price volatility and a 4% interest rate, only to show what this guarantee is worth in financial terms. The lower the market price, the more the guarantee is worth, the less the company's earnings depend on the price cycle, and the more its valuation shifts from that of a “cyclical stock” toward that of a “utility.”
Look at the risks on the other side too: government support can weaken when policy changes; a company with a government equity stake may make business decisions shaped by non-commercial factors; and once everyone recognizes the floor, the stock price will quickly price it in.
Energy: having oil doesn't mean having fuel
Energy independence isn't only about how much crude you can pump; it's also about how much gasoline, diesel and jet fuel you can refine. The US is a major crude producer, but its refining capacity has grown little for decades, and some refineries are closing. When refined products (especially diesel) are tight, refiners' margins (the crack spread) widen sharply, while crude producers don't necessarily benefit.
The links in the energy theme have different drivers:

Gold: a hedge against a splintering monetary order
Traditionally, gold moves opposite to real yields. But since 2022, central banks have bought more than 1,000 tonnes of gold a year, and that buying has clearly weakened the link between gold and real yields. Central banks buy gold largely to reduce their dependence on a single currency and a single financial system: the freezing of Russia's foreign exchange reserves in 2022 made many countries realize that assets held in another country's currency can be frozen in a conflict.
So in today's narrative, gold looks more like a hedge against “a splintering monetary order” and “internal risks in major economies.” Households in some large economies are also adding gold as their real estate and local financial assets come under pressure, which gives gold demand support beyond the macro picture.
Gold
Structural demand from central banks and households
Hedge against credibility and geopolitical risk
Relatively “clean”; no industrial cycle
Silver
The precious-metals narrative plus industrial demand (electronics, solar)
More volatile; affected by the economic cycle
For those who want to amplify the gold narrative and can stomach bigger swings
Remember the counterargument too: gold produces no cash flow, and the return from holding it comes entirely from someone else being willing to pay a higher price. If central bank buying slows, or real yields rise sharply, gold could go through a long stretch of sideways trading or even decline.

Chapter 6
Reshoring and tariffs
Don't ask who will bring the factories back; ask who will make money because everyone needs them. Where factories get built and who builds them is full of uncertainty, but whoever builds them has to buy equipment, use power, hire engineering firms and rent warehouses.
The “shovels” reshoring needs
Link
Why it's unavoidable
Types of companies often discussed
Engineering and construction (E&C)
Every factory and every production line needs someone to design and build it
Large engineering and construction firms
Electrical equipment
New factories and data centers all need grid connections; lead times for large transformers have at times stretched to several years
Makers of transformers, switchgear and grid equipment
Industrial automation
Labor at home is expensive, so reshored factories must be more automated
Robotics, control system and sensor companies
Electronics manufacturing services (EMS)
Brands don't want to build their own plants, so they outsource to domestic contract manufacturers
Electronics contract manufacturers and assemblers
Transport and logistics
Parts and finished goods have to move between new locations
Heavy truck makers, railroads, industrial real estate
Skilled-worker training
Long-running shortages of electricians, welders and machinists
Vocational education, staffing services
The lazy expressions are US infrastructure ETFs (for example, PAVE) and grid equipment ETFs. The theme's biggest risk is the cycle: industrial capital expenditure (capex) is very sensitive to interest rates, and when rates rise and subsidies wind down, projects get delayed or even canceled.
Who actually pays the tariff
Legally, the importer pays the tariff, but the economic burden is split three ways: foreign exporters (cutting prices to keep orders), importers (squeezing their own margins) and consumers (paying more). How much each one bears depends on who has more bargaining power.
For stock investors, what matters most is how much of the cost a company can pass through to customers, and whether customers buy less once it does. Here is a hypothetical company: revenue of 100, cost of goods of 60 (a 40% gross margin), with half of that cost coming from imports.
How much cost a company can pass on decides whether a tariff is a “nuisance” or a “profit killer”Figure 6-1 · Drag to adjust
Current demand elasticityDemand unaffected (elasticity 0)
—Added cost (% of revenue)
—Price increase / volume change
—Change in gross profit
—New gross margin
A price elasticity of demand of 1.0 means sales fall 1% for every 1% rise in price. With the default settings, a 25% tariff raises costs by 7.5; the company passes through half by raising prices 3.75%, sales fall 3.75%, and gross profit drops about 12.8%. Drag elasticity to 0 and full pass-through preserves gross profit completely; drag it to 2.0 and gross profit falls 15% even with full pass-through. Companies with strong brands and hard-to-replace products have low elasticity. That is “pricing power.”
Second-order effects of tariffs
Domestic competitors benefit: once imports get more expensive, companies making similar products at home can raise prices or take market share. Steel, some chemicals and manufacturing are typical examples.
Downstream users lose: manufacturers that use steel and aluminum as inputs see their costs rise.
Trade reroutes: some goods are re-exported through third countries, whose logistics and assembly businesses grow until the rules close the loophole.
Retaliation and negotiation: the other side's counter-tariffs hit export industries such as farm products and aircraft. Many tariffs end up as bargaining chips, announced, paused and adjusted again and again.
The last point is especially important. Tariff policy often follows a rhythm of “announce hard, then partly back down.” In April 2025, after sweeping tariffs were announced, stocks and Treasuries both fell sharply, and within a week most of the tariffs were paused for 90 days. When you trade tariff news, treat “a pause or an exemption” as a scenario that can appear at any moment: don't slash your positions in the first day's panic, and don't chase in the first day's cheering.
A practical test
On a company's earnings call, look for the answers to three questions: What share of its costs is imported? How much has it raised prices, and how have customers reacted? Is it adjusting its supply chain, and how long will that take? When a company answers all three clearly, its tariff risk is usually already under control.

Chapter 7
AI, power and robotics
In the policy narrative, AI isn't just a technology; it's a tool for lowering unit labor costs and keeping the nation competitive. Whichever company wins the model race, it has to buy power, buy hardware and connect to networks.
From apps to power plants: money flows downstream
The lower the layer, the closer it is to “bought no matter who wins”Figure 7-1
Competition is fiercest in the upper layers, where winner-take-all is most obvious. Demand in the lower layers is the sum of all the players above, but it is also limited by physical constraints (power, permits, equipment lead times). The labels on the right mark each layer's biggest risk.
This chart explains why the “picks and shovels” logic is so popular in the AI theme: it's hard to tell which model company will win, but their combined capital expenditure (capex) eventually turns into orders for chips, networking equipment, data center construction and power.
Power: the hardest constraint
Growth in data center power use has turned electricity from a slow-growing utility business into part of the tech theme. A few links worth watching:
Generation: sources that can supply steady power for the long term are most in demand, and big tech companies are snapping up long-term power purchase agreements (PPAs) for nuclear and natural gas power.
Grid equipment: transformers, switchgear and transmission lines have long lead times, and capacity expands slowly.
Gas turbines and cooling equipment: demand from data centers building their own power supply and cooling.
Networking and connectivity: high-speed networks within and between data centers; companies holding related patents and equipment also benefit.
The counterargument: power demand forecasts have been too optimistic many times in the past; gains in chip energy efficiency could cut the power used per unit of compute; and residents and governments in some places have started opposing new data centers over electricity prices, water and land. All of this could limit the pace of growth.
Robotics: AI in physical form
If AI lowers the cost of mental work, robots lower the cost of physical work. Their first stop is most likely factories and logistics warehouses: controlled environments, repetitive tasks, high labor costs and jobs that are hard to fill. This ties in directly with the reshoring theme: for reshored factories to make money where labor is expensive, they have to automate heavily.
Risk levels within the robotics theme vary widely. Established industrial automation companies have steady revenue and customers; humanoid robot makers and early-stage startups mostly don't have revenue at scale yet, and some have gone public through special purpose acquisition companies (SPACs), with high risks of dilution and failure. Putting them in the same basket mixes two completely different kinds of risk.
Four risks in the AI theme

Chapter 8
Household themes: uneven inflation, agriculture and healthcare
People have to eat and they have to see a doctor. When money is short they count every penny; when they have more, they buy experiences. These needs don't change with the political cycle, but inflation changes what they look like for different groups of people.
How inflation splits consumer spending
Inflation hits everyone differently. Lower-income households spend a bigger share of their income on food, rent and gasoline, so they are the most sensitive to rising prices. Higher-income households have a cushion of rising asset values, and their spending power is less affected. By some estimates, the top 10% of households by income account for nearly half of all consumer spending. Economists call this split “K-shaped” consumption.
Group
Typical behavior
Business models that benefit
Households under income pressure
Trading down: shopping at discount stores, buying store brands, swapping beef for cheaper protein
Here is a classic trap: a good company is not the same as a good price. Warehouse clubs are widely seen as a great business, and the trading-down narrative holds up, but if the stock already trades at a price-to-earnings ratio (P/E) in the dozens, the growth the narrative brings has long been priced in. Within the same narrative, a cheaper company the market has overlooked is often the better vehicle.
Payment networks are another clever way to express the theme: inflation pushes up the nominal amount people spend, so payment companies that charge a fee on transaction value see their revenue grow along with inflation, without bearing the pressure of rising product costs.
Agriculture: essential demand inside a cycle
Demand for agriculture is very stable, but prices are cyclical. Fertilizer, seeds, farm machinery and grain trading each have their own cycle:
Fertilizer: prices swing widely with natural gas (the feedstock for nitrogen fertilizer), geopolitical conflict and grain prices. Fertilizer stocks look cheapest at the price peak, because that is when earnings are highest. This is the classic trap of cyclical stocks.
Grain trading and processing: these businesses earn the spread on transport, storage and processing, so earnings are relatively stable, and they often pay a dividend.
Broad agriculture ETFs (such as MOO) cover several links at once.
Agriculture is a “wait for the price” theme: buy in stages near the bottom of the cycle, when dividend yields are higher, and hold patiently into the next cycle, instead of chasing in on headlines about soaring grain prices.
Healthcare and longevity: people are trying to buy more time
Population aging is one of the few trends you can predict decades in advance. More older people means steadily rising demand for medical devices, surgery, drugs and care services. There are several ways to express this theme, with very different levels of risk:
Type
Characteristics
Risk
Established medical device companies
Surgery volumes grow as the population ages; stable revenue
Valuations are often not cheap
Life science tools companies
Sell “picks and shovels” to the whole drug R&D industry
Exposed to R&D budgets and the funding environment
Small companies in a turnaround
New management, new products; could be sharply rerated
High chance of failing to execute
Cutting-edge anti-aging biotech
The most exciting story
Most have no revenue yet; very high failure rate
Healthcare also has a big new variable from recent years: GLP-1 weight-loss drugs. They affect not only drugmakers but possibly the long-term demand for food, beverages, medical devices and even airlines (fuel savings from lower average passenger weight). This is a good exercise in using second-order thinking to find winners and losers.
What household themes have in common
Demand for these themes is very certain, so their biggest risk is usually not demand but valuation and policy: drug price negotiations, health insurance reimbursement rules, food safety and subsidy policy. They work as the stable part of a portfolio, built up slowly with shares. They are not suited to betting on short-term swings with short-term options.

Chapter 9
Elections and policy cycles
Elections don't change the fact that people need to eat and use electricity, but they do change who pays, who gets subsidies and who gets taxed. You study policy cycles to judge how far a theme can run, not to bet on who will win.
Incentives in an election year
Those in power generally want a stable economy and a rising stock market before an election. In the US, the president's party has lost House seats in the midterm elections again and again throughout history, so in the year before a midterm, policymakers tend to have less tolerance for a big market drop.
This creates what the market calls the “policy put”: when a market drop is caused by policy itself, policymakers have an incentive to adjust the policy to stop the slide. The tariff pause in April 2025 is one example; the violent swings in the Treasury market at the time are widely seen as one of the reasons for the pause.
The policy put is not insurance
It only works when the drop is caused by policy. If the drop comes from inflation, earnings or credit problems, policymakers can do little, and a central bank facing high inflation has a hard time stepping in.
You can't know in advance where or when the put will come. People waiting for it are often forced to hit their stop-loss before it arrives.
Repeated policy puts make the market dependent on them, and risk builds up at ever higher levels.
How far each policy area swings
Different policy areas change by very different amounts after a change of government. The table below doesn't judge which policies are better; it only describes how much each one swings with the political cycle:
Policy area
Bipartisan consensus
What it means for investing
Defense budget
High
Durable theme; a change of government has little effect
Export controls on critical technologies
High
Restrictions on semiconductor equipment and critical materials will continue
Supply-chain security, critical minerals
Fairly high
The tools may change (subsidies, tariffs, equity stakes), but the direction won't
Tariffs
Medium
Both parties use them, but the scale and the targets differ widely
Drug prices
Medium
Both parties lean toward pushing drug prices down, by different means
Energy mix (conventional vs. clean energy)
Low
Swings sharply with the party in power; related subsidies may be rewritten
Financial regulation
Low
How strict bank capital requirements and merger reviews are changes with each administration
A practical rule: keep long-term positions in high-consensus themes, and trade high-swing themes only with a time limit. If you must hold a high-swing theme, cut the position before the election to a level you can live with “no matter which side wins.”
Volatility around elections
The options market prices in elections. In the week or month that contains election day, implied volatility (IV) on index options is usually noticeably higher than before or after. As with data release days, you can use the method from the Macro Trading Framework handbook to work out the expected move for election day alone, then compare it with your own view. Once the result is in, the uncertainty is gone and IV often falls quickly; people who bought protection and didn't get a big move lose money as volatility drops.
Once the results are in, the sectors most sensitive to policy react first: energy, healthcare, financials, defense, clean energy, and tariff-sensitive importers. The first-day reaction is often overdone, because the market is pricing “the most extreme version of the policy,” while the policy that actually takes effect is usually watered down by Congress and the courts.
Fiscal policy, government bonds and the central bank
Every government wants lower borrowing costs. The market cares about two things: whether the fiscal deficit keeps widening, and whether the central bank can make decisions independently, based on inflation and employment. When the market worries about either one, the term premium on long-term government bonds rises, gold strengthens and the dollar may weaken. Chapters 3 and 4 of the Macro Trading Framework handbook explain the mechanics in detail.
As an investor, neither question requires you to take a political stance. You only need to watch long-term yields, gold and the dollar together, and see whether the market is pricing in credibility risk.
Keep your politics out of your positions
Write about policy, not parties. In your investment notes, write “defense budget growing,” not “Party X will win, so buy defense.”
Run the “change-of-government test.” For each theme, ask: if the other side were in power, would this theme still hold? Only the part that still holds belongs in your core position.
Read both sides. Following media from only one point of view makes you systematically overestimate the odds that the policies you support will succeed.
Don't trade slogans. Until a statement on social media becomes an order, a law or a budget, it is worth at most a small short-term trade.
Size positions to survive any election result. Betting on an election result is not fundamentally different from betting on a coin toss.

Chapter 10
Execution: ETFs, two stock baskets and options
Picking the right theme is only the start. How you buy, how much you buy, whether you use options and when you admit you're wrong decide how much you finally take away from a correct narrative.
Layer 1: dollar-cost averaging into ETFs
For most themes, the simplest approach is to pick one or two thematic ETFs and buy a fixed dollar amount every month:
Decide how much to invest each month first, then decide what to buy. Keep the amount small enough that you can keep investing through a big market drop.
Check once a month, not every day. What you're checking is whether the narrative has changed, not whether the price has gone up.
If the narrative hasn't changed, keep investing. If your invalidation criteria are met, stop adding money, then decide whether to sell.
An ETF spreads out single-company risk; it doesn't let you stop thinking. You still need to check the evidence for the theme once a quarter.
Layer 2: individual stocks in two baskets
Lower-risk basket
Good companies with stable earnings and healthy finances
Mostly own the shares: find good companies, then patiently pick them up “on the cheap”
Sell puts only when implied volatility (IV) is high enough and you're willing to take the shares at that price
Once the stock position is built, consider selling covered calls into rebounds
Higher-risk basket
Good companies with high valuations, cyclical stocks, turnaround companies, early-stage speculative companies
Rules: small positions; wait for the price, wait for volatility, wait for the event
Never add on the logic that “it's down 30%, so it's cheaper”
A small call option position is sometimes cleaner than selling puts: the most you can lose is the premium
You can remember the rules for the higher-risk basket with three words: Small, Lazy, Late. Small positions, so that no single failure hurts the whole portfolio. Lazy: trade rarely and give the narrative time. Late: wait for the evidence before you get in, even if it means missing the earliest part of the rally.
Buy the stock or sell a put?
A simple rule of thumb:
Can't miss it → buy the stock Happy to own it, but fine to miss it → sell a put
For example: the stock is at $50 and IV is 45%. You sell a put that expires in 30 days with a strike of $47.5 and collect about $1.40 in premium. The probability of being assigned (buying the stock at $47.5) is about 36%. If the stock rises to $57.5 a month later, the person who bought the stock has made $7.5, while the put seller has made only $1.40. So selling puts suits underlyings where you can say, “If it falls, I'm happy to buy; if it rises, I won't mind missing it.”
Covered calls: premium is not profit
Selling calls against shares you own and collecting premium every month is the most common way to enhance income. But first, look clearly at what it costs:
The higher the IV, the more tempting the premium, and the more likely the shares get called awayFigure 10-1 · Drag to adjust
Simple annualized premium (monthly × 12)Probability of assignment at expiry
—Monthly premium
—Simple annualized (× 12)
—Probability of assignment
Calculated with Black-Scholes: stock at $50, 30 days to expiry. With the default settings the monthly premium is about 1.66%, close to 20% simple annualized, but each month there is about a 28% chance of being assigned and giving up all the gains above the strike. In a fairly priced market, the premium is just the price of that upside, not free money. So the extra income you actually keep is much lower. For moderately volatile stocks, a conservative and more realistic expectation is an extra 5% to 10% a year.
Two principles:
High implied volatility is often there because the market really does see high risk. Behind a fat premium there is often an event such as an earnings report, a lawsuit or a regulatory approval.
If you would regret having the shares called away, you shouldn't have sold the call in the first place. Don't sell covered calls on the stocks you like most and least want to sell.
By how well they suit covered calls, you can sort your holdings into four groups: moderately volatile stocks you'd be fine having called away (a good fit); more volatile stocks that need more active management (doable, but watch them closely); stocks you especially like and don't want to sell (only under certain conditions); and stocks where you haven't finished building the position (get the stock entry right first, then think about selling options).
Real diversification is about sources of risk
Owning twenty stocks doesn't mean you're diversified. Group your holdings by the risk they really depend on:
Source of risk
Holdings that may be hit at the same time
AI capital expenditure (capex)
Chips, networking equipment, data center construction, power equipment, some power generators
Interest rates
Small caps, real estate, utilities, high-valuation growth stocks
Industries that depend on specific subsidies or specific regulations
Single-country risk
Companies with large revenue or big supply chains in that country
If fifteen of your twenty stocks are in the first row, you have really made only one trade.
Cash is a position
Holding cash when there are no good prices is an active decision. Thematic investing especially needs cash: good themes always have pullbacks, and during a pullback only those with cash on hand can buy. Know clearly what you're waiting for: a price, an event or a data point. If you can't say what your cash is waiting for, it will soon be spent on impulsive trades.

Scenario exercises
Work out your own answer first, then open the item to compare.
01A politician says on social media that they want to put heavy tariffs on a category of imports. Shares of the related domestic producers rise 12% that day. Would you chase them?
First work out what stage of policy this is: it is only a statement, not yet an order or a law. Tariff policy often goes back and forth between announcement, pause and exemption, and the first day's gain prices in the most extreme version.
A better approach: don't chase. Put it on your watchlist. If a formal order is issued and the implementation details are clear, then assess how much market share the domestic producers can win, and whether their valuations already fully reflect it.
02You're very bullish on clean energy, and your position is 30% of your total capital. The election is close, and polls show a tight race.
The energy mix is a policy area with low bipartisan consensus that swings sharply with the party in power. A 30% position amounts to betting a large share of your capital on one election result.
Run the change-of-government test: if the other side were in power, which parts would still hold (such as grid upgrades and power demand from data centers), and which would be hurt (such as projects that depend on specific subsidies)? Cut the position to a level you can live with whichever side wins, and tilt your holdings toward the links that both parties support.
03A ceasefire is announced in a regional conflict. Energy stocks fall 5% that day, defense stocks fall 3% and airline stocks rise 8%. You hold a defense ETF. Should you sell?
Separate emergency spending from preparedness spending. If your reason for holding the defense theme is long-term preparedness spending (for example, countries pledging to raise their defense budgets), one ceasefire doesn't change that logic, and the first-day drop is more likely to be sentiment.
If your reason for buying was this particular conflict, then the ceasefire is your invalidation criterion, and you should handle it according to plan.
04A critical minerals company gets a government equity stake and a long-term price floor, and its stock triples in a month. Is it still worth buying?
The government floor really does lower its downside risk; it works like a put option. But after the stock has tripled, that protection has probably already been priced in, or even overvalued.
Use the narrative scorecard: durability may be high, but crowding and valuation score low, which puts it in the “wait” quadrant. Put it on your watchlist, and consider it once the price comes back to a reasonable range or once the company delivers its new capacity.
05You hold a growth stock you especially like. IV is 60%, and selling a call that expires in one month, 5% out of the money, would bring in about 5% in premium. Should you sell it?
An implied volatility (IV) of 60% says the market sees this stock as very risky, and the chance of being assigned is also high (about 36%). If it really does rally hard, you give up all the gains above the strike.
This is a stock you especially like and don't want to sell, so it falls in the “only under certain conditions” group. If you would regret having it called away, don't sell the call.
