Edgarton evaluates the Fund’s positions from Exhibit 1 along with two of his pro forma portfolios, which are summarized in Exhibit 2:
Edgarton expects a steepening yield curve, with short-term yields rising by 1.00% and long-term yields rising by more than 1.00%.
Based on Exhibits 1 and 2, which of the following portfolios is most likely to have the best performance given Edgarton’s yield curve expectations?
选项：
A. Current Portfolio
B. Pro Forma Portfolio 1
C. Pro Forma Portfolio 2
解释：
C is correct.
Given Edgarton’s expectation for a steepening yield curve, the best strategy is to shorten the portfolio duration by more heavily weighting shorter maturities. Pro Forma Portfolio 2 shows greater partial duration in the 1- and 3-year maturities relative to the current portfolio and the least combined exposure in the 10- and 30-year maturities of the three portfolios. The predicted change is calculated as follows:
Predicted change = Portfolio par amount × partial PVBP × (-curve shift in bps)/100
如题，用bullet, 不是看组合里中长期的比重最大的那个吗？ PRO1 三个组合里3-10比重最大的，所以选PRO1， 我做题角度哪里不对？
