Answer:
As a risk minimizer : Stock A has the lowest standard deviation, thus, it should be chosen, if it is to be held in isolation . Also stock B has the lowest beta, thus,it should be chosen, if it is to be held as part of a well - diversified portfolio.
The answer is A and B respectively
Explanation:
The standalone risk or standard deviation of the stocks is alleviated for a well diversified investor . So, in that case, the relevant risk would be the market risk or the beta.
When you see in isolation, relevant risk would be the standard deviation.
Therefore, as a risk minimizer : Stock A has the lowest standard deviation, thus, it should be chosen, if it is to be held in isolation . Also stock B has the lowest beta, thus,it should be chosen, if it is to be held as part of a well - diversified portfolio.
