A portfolio manager gathers the following information about three well-diversified portfolios and their sensitivities to four factors using a macroeconomic factor model:
The portfolio best suited to hedge an existing short exposure to Factor 3 is:
A Portfolio X.
B Portfolio Y.
C Portfolio Z.
解析：
A.Incorrect because Portfolio X is not a factor portfolio as it is sensitive to more than one factor. Therefore, it is not the portfolio best suited to hedge an existing exposure to Factor 3.
B.Incorrect because Portfolio Y has a sensitivity of 0 to Factor 3 and so will not be useful in managing an existing exposure to this factor.
C.Correct because Portfolio Z is a factor portfolio with exposure to only one risk factor and exactly represents the risk of that factor. As a pure bet on a source of risk, factor portfolios are of interest to a portfolio manager who wants to hedge that risk (offset it) or speculate on it. So, Portfolio Z is best suited to hedge an existing short exposure to Factor 3.
