Answer:

equal 0.

Explanation:

If both stocks are perfectly negatively correlated, then the standard deviation will always be 0. For example, if the variance of stock A is -0.5, then the variance of stock B will be 0.5, so the standard deviation will be 0. The variance of each stock will cancel the variance of the other one.
