"Sector rotation" describes how large institutional investors — pension funds, mutual funds, insurers — move capital between different sectors of the economy depending on what stage of the economic cycle they're in, rather than simply entering or exiting the market entirely.
The logic of the economic cycle
In early economic expansion stages, there's usually more appetite for cyclical sectors: discretionary consumer goods, technology, industrials — businesses that benefit from people and companies spending more. In slowdown or uncertain stages, capital tends to rotate toward defensive sectors: staples, healthcare, utilities — businesses whose demand doesn't depend as much on how well the overall economy is doing (people keep buying medicine and paying for electricity during a recession).
Why it's worth paying attention to
When you see an entire sector start showing sustained positive relative strength — not just one stock, but several from the same sector at once — it's usually a more meaningful signal than an isolated move by a single company. It can reflect a real shift in how large investors are positioning their capital, not just noise from a single headline.
How to cross-reference it with the scanner
If, while reviewing the day's results, you notice several stocks from the same sector showing up with high scores, an uptrend, and positive relative strength at the same time, it's worth asking whether that's a coincidence or reflects something broader happening in that sector — and use that as a starting point to dig into what's driving it.
