Step by Step Solution

Step 1: Given Information

The CAPM or the Capital Asset Pricing Model helps in establishing a fair value of stock in comparison to the stock’s current market value.

Step 2: Solution

If the CAPM is valid, the expected rate of return compensates only for systematic (market) risk as measured by beta, rather than the standard deviation, which includes non-systematic risk. Thus, in the above scenario, Portfolio A's lower expected rate of return can be paired with a higher standard deviation, as long as Portfolio A's beta is lower than that of Portfolio B.

Therefore this is not possible
