Question

Decreasing the number of stocks in a portfolio from 50 to 10 would likely ________________. A. increase the systematic risk of the portfolio B. increase the unsystematic risk of the portfolio C. increase the return of the portfolio D. decrease the variation in returns the investor faces in any one year

Answer 1

Option B, Increase the unsystematic risk of the portfolio, is the right answer.

Step-by-step explanation:

Option B is correct because unsystematic risk refers to the risk that can be reduced drastically by diversifying the investment or portfolio. A company can reduce such risk by investing in a large range of projects or in large companies. Therefore, if the diversification decreases, as we can see in the question that the stock portfolio decreased from 50 to 10 then the unsystematic risk will increase.
