What is beta? The volatility that a benchmark portfolio (S&P 500 index) or a market portfolio exhibits is known as systematic risk. Beta is the historical measure of risk of any individual stock or portfolio against the risk of the market portfolio. In other words, it measures the volatility of any security with respect to the overall market volatility.
