Two investment advisers are comparing performance. One averaged a 19% rate of return and the other a 16% rate of return. However, the beta of the first investor was 1.5, whereas that of the second investor was 1. a. Can you tell which investor was a better selector of individual stocks (aside from the issue of general movements in the market)

Cannot be determined

Explanation:

Data given in the question

For one, the Rate of return = 19%

For one, the Rate of return = 16%

And,

The beta of the first investor = 1.5

The beta of the second investor = 1

So for better selector, we need to take the market rate of return and the risk-free rate of return without these two we are unable to say which one is better selector
