Show Suggested Answer Hide Answer
Suggested Answer: D

The coefficient of variation is useful when the rates of return and standard deviations of two investments differ. It measures the risk per unit of return because it divides the standard deviation by the expected return. The coefficient of variation is much higher for Mustang_(0.910 = .9) than for Cornhusker (.15.20 = .75).

20% return sounds great, but that standard deviation is wild!

I feel like I’ve seen a similar question before, and it was all about standard deviation. So, I’m leaning towards B for Cornhusker being riskier.

I’m a bit confused about the coefficient of variation. Isn’t that supposed to help compare the risk relative to the return? Maybe Mustang is riskier after all?

I remember practicing a question like this where we had to compare risk using standard deviation. I think that makes Cornhusker the riskier stock.

I think Cornhusker is riskier because it has a higher standard deviation, but I’m not completely sure if that’s the only factor to consider.
