The Beta for a security is an alternative way of representing its (a) standard deviation. (b) riskfree return. (c) expected rate of return. (d) covariance with each other security. (e) covariance with the market. The CAPM assumes equilibrium in that (a) all investors desire the riskfree return. (b) the supply of securities is less than the quantity demanded. (c) the slope of the SML is 1. (d) the supply of securities is equal to the quantity demanded. The Market Model differs from the CAPM in that the Market Model (a) uses a riskfree return. (b) uses the market portfolio. (c) uses a market index. (d) describes how prices are not. Stock A has a standard deviation of 16% and a Beta of 1.2. The standard deviation of the market portfolio is 10%. Stock A's unique or unsystematic risk, expressed as a standard deviation, is: (a) 3.8%. (b) 11.98. (c) 12.28. (d) 10.6%. (e) 5.4%. Securities with large unsystematic risks (a) must have large expected returns. (b) will also have large systematic risks. (c) do not necessarily have large expected returns. (d) will have large Betas. Normative economics is the use of economics to (a) describe the market. (b) develop a descriptive model of the securities market. (c) develop risk measurement. (d) tell investors what to do
