Which of the following is an assumption of capital market theory? All investors:

A)
 see the same risk/return distribution for a given stock.
B)
 select portfolios that lie above the efficient frontier to optimize the risk-return relationship.
C)
 have multiple-period time horizons.

All investors select portfolios that lie along the efficient frontier, based on their utility functions. All investors have the same one-period time horizon, and have the same risk/return expectations.

Which of the following statements regarding the Capital Asset Pricing Model is least accurate?

A)
 It is useful for determining an appropriate discount rate.
B)
 It is when the security market line (SML) and capital market line (CML) converge.
C)
 Its accuracy depends upon the accuracy of the beta estimates.

The CML plots expected return versus standard deviation risk. The SML plots expected return versus beta risk. Therefore, they are lines that are plotted in different two-dimensional spaces and will not converge.

When the market is in equilibrium:

A)
 all assets plot on the SML.
B)
 all assets plot on the CML.
C)
 investors own 100% of the market portfolio.

When the market is in equilibrium, expected returns equal required returns. Since this means that all assets are correctly priced, all assets plot on the SML.

By definition, all stocks and portfolios other than the market portfolio fall below the CML. (Only the market portfolio is efficient.
