Part 7 · Connecting the economy to stocks · Lesson 35
Different sectors are strong in different seasons of the economy
When the economy changes seasons, the star sectors of the market change too. Let's put the textbook "sector rotation clock" side by side with the real scoreboard.
QToday's question
Are the sectors that are strong when the economy is good, and the ones that hold up when it is bad, really fixed?
In the year after the US stock market bottomed on March 23, 2020, the energy sector ETF rose 108%, while consumer staples rose a little over 40%. Two years later, in 2022, it was the reverse: only energy rose, up 57.6%, while consumer discretionary fell 36.8%. The same sector swings between lead and supporting role from year to year. In this lesson you learn the principle of "sector rotation," where the strong sectors change with the season of the economy, and use the real scoreboard to check when the textbook was right and when it was wrong.
MAPLearning map for this lesson
We build it up in three steps. At the end of each step, a 'Quick check' lets you test your understanding before moving on.
In Lesson 5 you learned that the economy cycles through the four seasons of recovery → expansion → slowdown → recession, and that some sectors are cyclical and others defensive. In Lesson 22 you saw why consumer discretionary and consumer staples move differently, and in Lesson 11 and Lesson 18 that inflation and interest rates produce a different scoreboard for each sector. And in Lesson 34 you confirmed that stock prices move before the economy. This lesson ties these pieces together into a single "sector map by season."
- STEP 1 · Core conceptsThe star changes with each season of the economy
Describe, with the clock, the sectors that are textbook-strong in recovery, expansion, slowdown and recession, and explain why using earnings, interest rates and inflation.
- STEP 2 · Understanding the mechanismWhy do sectors follow the seasons?
Explain why rotation happens using each sector's sensitivity of earnings and of interest rates and inflation, and judge "strong" by .
- STEP 3 · Applying it2020–2023: the scoreboard of four scenes
Use real sector ETF returns to tell when the textbook was right and when it was wrong, and follow the steps for guessing the current season and picking candidate sectors.
STEP 1The star changes with each season of the economy
Even if your closet holds clothes for all four seasons, the season decides what you take out and wear now. Sectors in the stock market are similar.
An easy analogy · A store display that changes with the seasons
Think of a neighborhood supermarket. In spring, seedlings and hiking wear take the entrance display; in summer, fans and ice cream; in autumn, camping gear; in winter, heaters and tangerines. The goods the store sells are the same all year, but the goods customers crowd around change with the season.
The stock market also has its displays, the sectors, all year round. But the display that money crowds around changes with the season of the economy. This flow is called .
Each sector rides the economy to a different degree
In Lesson 5 we separated , whose earnings swing widely with the economy, from , whose demand doesn't shrink much even in a downturn. The classic pair from Lesson 22 is (autos, travel, home appliances) and (food and beverages, household goods). When money gets tight, people put off a new car but keep buying toothpaste and rice.
Lay this difference over the four seasons of the economy, and an order of sectors that were "generally strong" in each season emerges. In the investment industry it is often drawn as a clock face. Below is a summary of that textbook breakdown. The US market divides sectors into 11 , and there are that hold each sector whole, which makes it easy to compare performance by sector.
See it in a chart: the sector rotation clock
Tap the four slices of the clock. For each season it shows what the interest rate, inflation and economic signals look like, the sectors the textbook calls strong and weak, and what to watch out for in practice.
The clock is a textbook breakdown to aid understanding. The length of the real seasons differs every time, and sector rankings often change even within the same season. The boundaries between seasons are officially announced only after they have passed (Lesson 5).
If you turn the clock one full circle, a pattern appears. In the recovery phase, when the economy passes its bottom, financials (where lending will grow again) and consumer discretionary (where spending revives) lead; in the expansion phase, when companies add capacity, IT and industrials lead. In the slowdown phase, when demand outruns supply and commodity prices and inflation rise, energy and materials lead; in the recession phase, when unemployment rises and earnings shrink, sectors with steady demand like essentials, electricity and medicines (consumer staples, utilities and health care) hold up relatively well. Sectors strong near the bottom of the economy are sometimes called "early-cycle," and those strong near the peak "late-cycle" ().
Quick checkUnemployment has started to rise and corporate earnings forecasts are being cut one after another. Looking at the textbook clock, which sectors are relatively easy to hold up?
STEP 2Why do sectors follow the seasons?
Knowing why the order arises is far more useful than memorizing the order of the clock. The three levers you have learned so far are enough to explain it.
Three levers that move sectors
Earnings lever: sensitivity to the economy
How much earnings grow when the economy improves and how much they shrink when it worsens. Industrials, materials and semiconductors, with large fixed costs, see earnings swing widely on even a small change in revenue (Lesson 3).Multiple lever: sensitivity to interest rates
When rates rise, the present value of far-future earnings shrinks, so multiples fall for growth stocks and IT, while banks and insurers, whose loan-deposit spread widens, are relatively favored (Lesson 17, Lesson 18).Inflation lever: pricing power
When inflation rises, sectors that can raise their own product prices along with it (energy, materials) hold up, while sectors whose only cost rises see earnings shrink (Lesson 11).When the season of the economy changes, these three levers move together. In recovery, rates are low and earnings start to grow quickly from the bottom, so the cyclical sectors whose earnings had fallen the most rebound the most. In slowdown, high inflation and rates make the multiple lever press down IT and consumer discretionary, while the inflation lever supports energy and materials. In recession, the earnings lever hits cyclical sectors hard, but rates begin to fall, and the appeal of defensive sectors with steady dividends grows.
| Season | Earnings | Interest rate | Inflation | Generally strong sectors |
|---|---|---|---|---|
| Recovery | Rebounding from the bottom | Low (late in the cutting cycle) | Low | Financials, consumer discretionary, real estate |
| Expansion | Growing steadily | Rising slowly | Stable | IT, industrials, communication services |
| Slowdown | Growth slowing | High (rising) | High | Energy, materials, (consumer staples, health care) |
| Recession | Declining | Starting to fall | Coming down | Consumer staples, utilities, health care |
"Strong" means better than the market
In sector rotation, a "strong sector" means one that fell less than, or rose more than, the market as a whole. So a sector's return should always be viewed next to the market's return. This is called . From Feb 19 to Mar 23, 2020, while the ETF tracking the S&P 500 (SPY) fell 34.1% on the COVID shock, three sectors performed as follows.
Source: Yahoo Finance daily closes (price returns excluding dividends), Feb 19 – Mar 23, 2020. Return relative to the market is a Robin Invest calculation (sector return − SPY return).
Consumer staples succeeded at "defense," but still fell by a quarter. This means that buying defensive sectors in a recession doesn't make you money; it is closer to losing less. Over the same period, energy fell far more than the market as the economic shock combined with a production race among oil producers to collapse oil prices (for oil, see Lesson 29).
Sectors change before the seasons do
In Lesson 34 you learned that stock prices move months ahead of the economy. Sector rotation is the same. The market buys and sells the "next season," not the "current season." So recovery-phase sectors rise first while the economy is still in the middle of a recession, and slowdown-phase sectors begin to lead while the economy still looks great. By the time the news says "economic recovery," a good part of the recovery-phase sectors may already be (Lesson 20).
Common misconceptions
- "If you just call the clock right, you always make money?"
- No. Which season it is becomes clear only after it has passed, and the length of seasons differs every time. Even within the same season, other forces such as rates, exchange rates and oil flip the sector rankings.
- "Defensive stocks rise in a recession?"
- Generally they "fall less." In the 2020 plunge, consumer staples also fell 24.6%. And utilities fell 36.0% over the same period, more than the market (−34.1%). Defensive sectors can fail at defense too, depending on the nature of the crisis.
- "IT is an expansion-phase sector, so you should avoid it when recession worries are big?"
- A sector's performance depends heavily not just on the economic season but on that sector's own story. In 2023, when recession worries were big, the technology sector rose 54.7%. We look at this in detail in STEP 3.
Quick checkIn one year the whole market was −10%, sector A was −4% and sector B was +2%. What is each sector's return relative to the market?
STEP 32020–2023: the scoreboard of four scenes
Now it's time to hold the textbook clock up against the real scoreboard. Because the economy's seasons changed quickly over these four years, they make good teaching material.
Four scenes for the 11 US sectors
Tap a tab to change the scene. Each bar is the price return of a sector ETF, and the black vertical line is the return of the market (SPY) over the same period. Green bars are sectors that were stronger than the market, and orange bars are sectors that were weaker.
Feb 19, 2020 → Mar 23, 2020 · COVID plunge
Source: price returns (excluding dividends) calculated from Yahoo Finance daily closes. SPDR sector ETFs (XLK, XLF, XLE, XLV, XLY, XLP, XLI, XLU, XLRE, XLB, XLC) and SPY. Based on closing prices on the end date of each period, checked 2026-10-05. The S&P 500 peak of 3,386.15 (Feb 19, 2020) and low of 2,237.40 (Mar 23, 2020) are from FRED SP500.
1. Plunge (Feb 19 – Mar 23, 2020). The US economy peaked in February 2020 and entered a brief recession (a March–April recession per FRED USREC). During this month or so, consumer staples (−24.6%) and health care (−28.3%) fell less than the market (−34.1%), defending just as the textbook says. Utilities, by contrast, failed to defend at −36.0%, and energy (−57.0%) and financials (−43.3%) collapsed the most.
2. Recovery (Mar 23, 2020 – Mar 31, 2021). In the year after the bottom, energy (+108.1%), materials (+105.5%), industrials (+101.9%), financials (+92.8%) and consumer discretionary (+92.0%) beat the market (+77.8%), while consumer staples (+40.5%) and utilities (+42.5%) lagged far behind. This fits well with the textbook idea that cyclical sectors lead the recovery. However, energy, a "late-cycle" sector, coming in first differs from the textbook. It was the result of the sector that had fallen the deepest bouncing the highest.
3. Tightening (2022). This was the year inflation hit its highest in 40 years and the Fed raised rates quickly (Lesson 13). Energy rose 57.6%, the only one of the 11 sectors to rise, while utilities (−1.5%), consumer staples (−3.3%) and health care (−3.6%) far outperformed the market (−19.5%). Conversely, the rate-sensitive communication services (−38.2%), consumer discretionary (−36.8%), real estate (−28.7%) and technology (−28.4%) were the weakest. It looks almost the same as the textbook for a slowdown.
4. Rebound (2023). 2023 was a year when the term spread was deeply inverted and recession worries were big (Lesson 16). By the textbook, defensive sectors should have been strong, but in reality technology (+54.7%), communication services (+51.4%) and consumer discretionary (+38.4%) led the market (+24.3%), while utilities (−10.2%), energy (−4.1%) and consumer staples (−3.4%) were the weakest. The expected recession did not come, and stories specific to certain sectors, such as AI expectations, had more force than the economy's season.
The scorecard for the four scenes
The first scene matched the textbook about halfway, the second and third mostly matched, and the fourth was far off. The clock is a compass that shows direction, not an answer sheet that gets the ranking right.
The Korean market had similar scenes. In 2022, when rates rose fast, KOSPI fell 24.9% while the KODEX Insurance ETF rose 14.8% and KODEX Healthcare fell 28.4% (Lesson 18, based on Naver Pay Securities prices). You should also note that, because Korea has a large export share, the seasons of export sectors such as semiconductors, autos and shipbuilding depend heavily on the global economy and the exchange rate (Lesson 26).
For stocks, like this: use the clock as a list of questions
| Order | What to do | Where to look |
|---|---|---|
| 1 | Guess the current season: check PMI and the leading index, jobs, inflation and the direction of rates | Lessons 6 and 19, Macro Map current phase |
| 2 | Pick candidate sectors for the next season from the clock | The sector rotation clock above |
| 3 | Check how the candidate sectors are exposed to interest rates, exchange rates and oil | Impact map, Theme Map |
| 4 | Ask whether it is already priced in: check the return relative to the market over the last few months | Lessons 20, 34 |
When the news says "defensive stocks strong on economic slowdown worries," you can read it as a sign that slowdown/recession sectors are moving, and when it says "cyclical stocks rebound on rate-cut expectations," that recovery sectors are moving. What matters is how much of that story is already in the price.
Not always. The sector rotation clock is only a tendency averaged over several business cycles, and the cause of a crisis (pandemic, inflation, financial accident) and stories specific to a sector (tech innovation, regulation, raw-material supply) can easily change the order. Don't use it as a signal to buy or sell a particular sector or stock.
Quick checkIt is a year of high inflation with the central bank raising rates quickly. By the textbook clock and the 2022 scoreboard, which sectors are likely to be relatively weak?
✓What we learned today
- Sector rotation is the flow in which the relatively strong sectors change one after another as the economy's seasons change. By the textbook, financials and consumer discretionary are strong in recovery, IT and industrials in expansion, energy and materials in slowdown, and consumer staples, utilities and health care in recession.
- Sectors follow the seasons because of three levers. Each sector differs in whether its earnings swing widely with the economy, whether its multiple is sensitive to interest rates, and whether it can raise prices when inflation rises.
- "Strong" is a relative term: fell less than, or rose more than, the market as a whole. In the 2020 plunge, consumer staples at −24.6% merely fell less than the market (−34.1%); they did not rise.
- The real scoreboard often departs from the textbook. In the 2020 recovery, energy rose the most, and in 2023, when recession worries were big, it was technology and communication services, not defensive sectors, that led the market.
- The clock is a list of questions, not an answer sheet. Use it in this order: guess the current season from indicators, check candidate sectors with the Macro Map and Theme Map, and ask whether it is already priced in.
With the sector rotation clock you've got a feel for "which sectors in which season." In reality, though, interest rates, exchange rates and oil prices move at the same time, so it is often hard to describe things with a single season. In the next lesson we load the real data from the Robin Invest Macro Map and practice reading several factors at once as a sector map.
Quiz5-question quiz
Pick an answer and it's graded right away with an explanation.
Q1. On the textbook sector rotation clock, which sectors are generally strong in the economic "recovery" phase?
Once the economy passes its bottom, the expectation that low rates will revive lending and spending is priced in first. That is why financials and consumer discretionary are cited as the representative sectors of the recovery phase.
Q2. What is the best reason energy and materials sectors generally hold up in the "slowdown" phase, when inflation is high and rates are rising?
In the slowdown phase, the inflation lever moves a lot. When commodity prices rise, energy and materials companies also raise the price of what they sell, so their earnings find it easier to hold up (Lesson 11).
Q3. From Feb 19 to Mar 23, 2020, SPY was −34.1% and the consumer staples sector was −24.6%. What is the best interpretation?
"Strong" in sector rotation is relative to the market. −24.6 − (−34.1) = +9.5 pp, so it was relatively strong, but in reality it lost nearly a quarter.
Q4. Despite big recession worries in 2023, the technology sector led the market with +54.7%. What does this case show?
The expected recession did not come, and a sector-specific story such as AI expectations had more force than the economy's season. The clock is a compass, not an answer sheet.
Q5. When the phrase "economic recovery" starts appearing in earnest in the news, what is the first question to ask about recovery-phase sectors?
Stock prices move before the economy (Lesson 34). Sector rotation also buys and sells the next season in advance, so by the time the news talks about recovery it may already be priced in (Lesson 20).
