Last lesson covered the weather — rates and inflation. This one covers the seasons. Economies expand, overheat, contract and recover in rough cycles, and as they turn, money flows out of some sectors and into others. That flow has a name, sector rotation, and understanding it does two things for you: it explains market moves that otherwise look random, and — more importantly — it will stop you from making the classic mistake of chasing it.
Two kinds of businesses
Start with the distinction everything else builds on. Some businesses breathe with the economy and some do not.
Cyclicals sell things people can delay: excavators, cars, vacations, houses, advertising. When times are good their sales boom; when times tighten their revenue does not dip — it dives, because a postponed excavator is a cancelled excavator. Caterpillar, Ford, airlines, homebuilders, banks, miners.
Defensives sell things people buy regardless: toothpaste, electricity, groceries, medicine. Nobody doubles their soda consumption in a boom or halves their insulin in a recession. Coca-Cola, utilities, food, healthcare. Their earnings are boring on purpose — and in a downturn, boring is a superpower.
Same economy, two completely different exposures to it. Rotation is just the market shifting its weight between these two poles — and a few stops in between — as its expectations for the cycle change.
The four seasons, roughly
The textbook cycle has four phases, each with historical leaders:
- Early recovery — the economy turns up from a trough, rates are low, credit flows again. Historically led by banks, industrials, small caps and consumer discretionary — the most beaten-down, economically sensitive names snap back hardest.
- Mid-cycle — steady growth, calm inflation, the longest phase. Technology and broad growth tend to lead; with the economy neither hot nor cold, the market pays up for whoever can grow fastest.
- Late cycle — the economy overheats, inflation stirs, central banks tighten. Energy and materials historically shine as commodity prices run, while expensive growth stumbles under rising rates — Lesson 3’s gravity at work.
- Contraction — growth rolls over. Money hides in consumer staples, utilities and healthcare — the defensives, whose earnings do not care — and in bonds.
Read that list and rotation stops being mysterious. It is not fashion; it is the market repricing whose earnings survive the next phase. Of course money leaves homebuilders when rates rise. Of course toothpaste outperforms when GDP rolls over.
The catch: the map has no “you are here”
Now the honest part. Those four phases are blindingly obvious in hindsight and genuinely murky in real time. Halfway through a cycle, the data is always mixed: some indicators scream late-cycle, others mid-cycle; every recession that did not happen was preceded by confident calls that it would. Economists as a profession have famously predicted far more recessions than have occurred. The phases only get their clean labels after the fact.
Which is why chasing rotation usually fails. To profit from it you have to get two timing decisions right — when to jump in and when to jump out — against professionals doing this full-time, while paying a tax bill on every hop (wait for Lesson 7). Miss the turn by a quarter in either direction and you reliably arrive at each sector just after its run: buying energy after the commodity spike, hiding in staples after the crash, re-entering tech after the recovery is priced. Rotation-chasing turns one hard problem — picking good businesses — into a sequence of hard problems back to back.
What to do instead: own the cycle
The point of this lesson is not a trading signal. It is three quieter uses:
- Diversify across the phases on purpose. A portfolio holding quality cyclicals and defensives and growth is never entirely right for the season — and never entirely wrong. You already built this instinct in the Intermediate course; now you know why it works: you own every season’s leader in advance.
- Use the cycle as a valuation cross-check, not a timer. When a cyclical looks historically cheap on peak earnings, Lesson 2 should be ringing in your ears. When defensives get expensive during a panic, that is the crowd paying up for shelter. Rotation tells you why the price is what it is.
- Let it explain your portfolio’s bad quarters. When your industrials lag while staples run, that is not your thesis failing — that is a season. The film, not the photograph, is what you judge.
And if you remember one line: you do not need to predict the seasons if you are dressed for all of them. Next lesson, we put valuation, traps and cycle-awareness together and let Quorum do the first pass of the hunting for you.
