T/F -Variance is a measure of the variability of returns, and since it involves squaring the deviation of each actual return from the expected return, it is always larger than its square root, the standard deviation. -If an investor owns two stocks, one whose standard deviation is 0.21 and the other whose standard deviation is 0.10, the required return could be higher on the stock with the lower standard deviation. -Different investors have different degrees of risk aversion but this...

T/F The variance of an asset's return can be less than the standard deviation of that asset's return. If an investor owns two stocks, one whose standard deviation is 0.21 and the other whose standard deviation is 0.10, the required return will be higher for the stock with the higher standard deviation. Different investors have different degrees of risk aversion, and the result is that investors with greater risk aversion tend to hold securities with lower risk (and therefore a...
