Quantitative Methods Q170

-Fatima: Covariance lies within the range -1 < Covariance < +1
-Taimour: The covariance of a stock with itself is equal to its own variance.
-Vishal: The covariance of returns is negative when the return of one asset is above its expected value given that the return on the other asset tends to be below its expected value.

Option : C
Explanation : Fatima is incorrect because covariance may range from negative infinity to positive infinity. Taimour and Vishal are correct.
