Question

According to the mean-variance criterion, portfolio A is better than portfolio B for a risk-averse investor whenever _____.

Answer 1

Answer: d. E(rA) ≥ E(rB) and σA ≤ σB

Step-by-step explanation:

The options are:

a. E(rA) ≤ E(rB) and σA ≤ σB

b. E(rA) ≥ E(rB) and σA ≥ σB

c. E(rA) ≤ E(rB) and σA ≥ σB

d. E(rA) ≥ E(rB) and σA ≤ σB

Mean-variance criterion is when the means and the variances of the return of different portfolios are used as a basis to select a portfolio.

An investor will choose the portfolio that has a lower risk which is denoted by the standard deviation. Therefore, option D is correct.
