Answer to Question 1

Answer: The equation for the SML is E(ri) = rf + E(rm) - rf  i, where: E(ri) is the expected return on an asset, rf is the risk-free rate, i is beta the measure of nondiversifiable risk for asset i, E(rm) is the expected return for holding the market portfolio of risky assets, and E(rm) - rf is the market risk premium that an investor can expect to earn for holding the market portfolio. If an asset has a beta of 2.0, an investor can expect to receive twice the market risk premium in addition to the risk-free rate of return. A common misconception is that the investor can expect to receive twice the rate of return as the market portfolio, but only the risk premium is impacted by the level of risk.

Answer to Question 2

Answer: FALSE
Explanation: According to the security market line, there is a reward for waiting. The risk-free asset can provide you with a positive return without uncertainty of return.
