Market beta refers to the measure of how much an investment, such as a stock or a portfolio, moves in relation to the overall market. It shows the level of sensitivity of an investment to changes in the market. A
market beta of 1 indicates that the investment moves in line with the market, while a beta less than 1 suggests the investment is less volatile than the market, and a beta greater than 1 means the investment is more volatile than the market.
