What is Sectoral Relative Strength?
Sectoral relative strength compares the price performance of different sector indices against each other and against the broad market (Nifty 50). By rebasing all sectors to a common starting point (0%), you can see which sectors are gaining or losing ground relative to others. A sector that rises more than Nifty is showing relative outperformance; one that rises less or falls more is showing relative underperformance.
This is different from looking at absolute index levels. A sector index might be at an all-time high but still underperforming relative to the market. Relative strength strips away the overall market direction and focuses purely on which sectors are attracting more capital.
