Sector Rotation in India
Different sectors lead at different times. Sector rotation is the study of how that leadership moves and how to see it in the data.
- No sector leads forever: leadership moves with earnings, interest rates and money flows.
- Measure it with returns relative to the market and with breadth inside each sector.
- Leadership that has lasted a few months tends to persist for a while, but turns can be sudden.
Why leadership changes
Banks may lead when credit growth is strong, IT when the rupee weakens and global demand is firm, metals when commodity prices rise, and defensive sectors like FMCG and pharma when investors want safety. The textbook story links this to the economic cycle, but in real markets the order is messy and the timing varies.
How to see it in the data
The Sector Strength page combines these into a leading score for about 48 NSE indices. The Micro Sector Tracker does the same for about 80 small industries that have no NSE index of their own.
- Relative returns over 1, 3 and 6 months against Nifty 500.
- A rotation graph that shows whether each sector's lead is growing or fading.
- Breadth inside the sector: how many of its stocks are above their 50-day average. A sector index can be pulled up by one heavy stock.
Common mistakes
- Buying the sector that led last year. Last year's leader is often this year's laggard.
- Using only one period. A sector can be strong over 1 month and weak over 6.
- Forgetting position size. Sector bets are more concentrated and swing more than the index.
Common questions
What is sector rotation?
Sector rotation is the shift of market leadership from one group of industries to another as conditions change. It is studied by comparing each sector's returns with the overall market.
How long does a sector stay in the lead?
It varies from a few weeks to a few years. Leadership over several months tends to persist for a while, which is the momentum effect, but reversals can be sharp.
Which index should sectors be compared with?
A broad index such as Nifty 500 is a good benchmark because it includes large, mid and small companies.
