Cyclical vs Durable Businesses
Cyclical companies are tied to the economic cycle: their revenue and profit swing hard with demand. Durable businesses keep grinding through cycles.
Why this matters for beginners
Buying a cyclical at peak earnings can look 'cheap' on P/E and turn out to be very expensive. Recognising the cycle changes how you read valuation.
Main explanation
Cyclical examples: semiconductors, airlines, autos, energy, banks, industrials. Durable examples: consumer staples, large software, utilities, some healthcare.
On cyclicals, low P/E often appears at the top of the cycle (earnings are temporarily high) and high P/E at the bottom (earnings are temporarily low). The 'cheap' signal can be exactly wrong.
Healthy ways to value cyclicals include normalised earnings (an average across a cycle), price-to-book, and cash flow over a multi-year window.
Even durable businesses are not immune, recessions, regulation, and disruption still hit them. They just swing less.
Example using a real company
MU (memory chips), BA (aircraft), XOM (oil) and ASML (lithography equipment) all show different flavours of cyclicality.
- →Memory chips: revenue can double in an upcycle and halve in a downcycle. Same company, very different earnings.
- →Consumer staples like household goods barely move when GDP wobbles.
Common beginner mistakes
- ✕Using peak-cycle P/E as if it were normal.
- ✕Assuming any low P/E is a bargain.
- ✕Treating semiconductor stocks as 'tech' rather than cyclical tech.
Key terms
- Cycle
- Recurring expansion and contraction in demand for an industry.
- Normalised earnings
- Average earnings across a full cycle, used to value cyclicals.
- Operating leverage
- How much profit moves when revenue moves, high for many cyclicals.
Key takeaways
- 01Cyclicals look cheap at the top and expensive at the bottom.
- 02Value them across a cycle, not on one quarter.
- 03Durables swing less but aren't risk-free.
Check yourself
- 01A low P/E on a cyclical always means it's cheap.
- 02Memory chip makers are cyclical.
- 03Normalised earnings average across a full cycle.
Try the concept on a real company
Analyze MU, BA, XOM, and ASML. Look at the bear case and risks sections, where do you see cycle risk explicitly mentioned?
