Answer:
The SML relates a stock's required return to its market risk. The slope and intercept of this line cannot be controlled by the firms' managers, but managers can influence their firms' positions on the line by such actions as changing the firm's capital structure or the type of assets it employs.
Explanation: The SML can help to determine whether an investment product would offer a favorable expected return compared to its level of risk. The formula for plotting the SML is: Required Return = Risk-Free Rate of Return + Beta (Market Return - Risk-Free Rate of Return).
