Beta measures the volatility or riskiness of a stock. The beta of the benchmark index fund is usually 1.
If the stock is more risky than the index fund, the beta would be greater than 1
If the stock is less risky than the index fund, the beta would be less than 1
The higher the beta, the higher the required return on the stock as investors would want to be compensated for bearing risk.
