What does the equity risk premium reflect?

The equity risk premium represents the additional return that investors expect to receive for taking on the higher risk associated with investing in equities over risk-free investments, such as government bonds. This concept arises from the understanding that equities typically have higher volatility and uncertainty compared to safer investments.

Investors require this premium as compensation for the additional risk of loss in their equity investments. Consequently, the equity risk premium is a critical component of investment decision-making, influencing portfolio allocation and expected returns. The rationale is that if investors are to commit their capital to riskier assets, they must have an incentive to do so, hence the expectation of higher returns from equities compared to safer options.

The other options do not capture the essence of the equity risk premium. The additional return expected from risk-free investments is not related to risk, as it refers to safer assets rather than riskier equities. The fixed return from government bonds indicates no risk premium, as these are considered low-risk investments without the additional expected return that equities provide. Lastly, defensive stocks usually refer to those that provide stable and reliable returns even in economic downturns, which does not inherently relate to the broader concept of risk premium associated with the entire equity market.
