Final answer:
An investment that falls below the security market line (SML) would indicate that it is undervalued.
Step-by-step explanation:
When reviewing the investment policy statement annually, an investment that falls below the security market line (SML) would indicate that it is undervalued. The security market line (SML) is a graphical representation of the relationship between risk and return for individual securities.
Thus, It typically shows the expected return of a security based on its beta, which measures its systematic risk. If an investment falls below the SML, it means that it is providing a higher return for its level of risk, making it undervalued. For example, if a stock has a beta of 1 and is expected to provide a return of 10%, but falls below the SML and is actually providing a return of 15%, it would be considered undervalued.
