The beta coefficient is a key measure in finance that indicates the level of systematic risk associated with a particular security compared to the overall market. It reflects the tendency of an investment's returns to respond to market movements. A beta of 1 suggests that the security's price is expected to move with the market; a beta greater than 1 indicates greater volatility (higher risk), while a beta less than 1 indicates less volatility (lower risk) compared to the market.

Understanding beta is crucial for investors when assessing potential investments within the context of their overall risk tolerance and the performance of the market. By indicating how a security might behave in relation to market fluctuations, the beta coefficient allows investors to make more informed decisions regarding asset selection and portfolio management.

The other choices do not capture the specific role of beta in measuring risk. While liquidity pertains to how easily an investment can be bought or sold without affecting its price, and expected returns concern the anticipated profitability of an investment, these concepts do not align with the fundamental purpose of the beta coefficient. Additionally, fixed income performance typically relates to bonds and interest rates rather than the market-risk dynamic encapsulated by beta.
