In finance, beta measures the volatility or systematic risk of a security or portfolio compared to the overall market.
Since an index like Nifty 50 represents the overall market or a broad market segment, it is assigned a beta of 1 by definition.
- A beta of 1 means the index's price tends to move in line with the market.
- Stocks with beta greater than 1 are more volatile than the market.
- Stocks with beta less than 1 are less volatile.
