- -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.
The statements made by which of the students are most likely correct?
- Option : C
- Explanation : Fatima is incorrect because covariance may range from negative infinity to positive infinity. Taimour and Vishal are correct.
- Option : C
- Explanation : The correlation of 1.0 signifies that the securities are perfectly positively correlated; it implies that they will move in the same direction so the portfolio cannot benefit from diversification.
