The economy goes in waves from deep crises to wild booms. Sector rotation is about surfing these waves by moving your capital to the industries (sectors) that historically perform best in the current phase of the economy.
"Life is a game of boomerangs. Our thoughts, deeds and words return to us with astounding accuracy."
— Florence Scovel Shinn
Just like in the quote above, the economy moves in circles and cycles that constantly return. A skilled investor knows which phase is coming and positions themselves accordingly.
The four economic phases
When we talk about sector rotation, we usually divide the economy into four phases:
- Early recovery: The economy begins to recover after a downturn. Interest rate sensitive sectors like finance and real estate, as well as consumer discretionary (things we buy when we have more money), often perform well.
- Mid-cycle: Growth is stable. Technology companies and industrials often thrive here.
- Late cycle (the peak): The economy is booming, and inflation often rises. Commodities and energy tend to be the winners.
- Downturn (recession): The economy slows down. Now investors seek safety in defensive sectors such as healthcare, consumer staples, and utilities (electricity and water). People need food and medicine no matter how the stock market is doing!
Timing is everything: The hardest part of sector rotation is not knowing which sectors to choose, but accurately predicting when the economy actually shifts phases.
