问题如下：
Beatriz Maestre is a fixed-income consultant who has been retained by Filipe Ruelas, the CFO of Cávado Produtos Agricolas, SA (Cávado). Cávado is a manufacturer of prepared foods headquartered in Braga, Portugal.
During the meeting, Maestre presents some information about Cávado’s pension fund, which is primarily invested in corporate bonds with a mixture of investment-grade and speculative-grade issues. This information is presented in Exhibit 1.
Ruelas explains that he uses futures contracts on euro-denominated German government bonds to reduce the duration gap between assets and liabilities. However, because the pension fund has only a small surplus and he would like to increase this surplus through active management of the portfolio, he employs a contingent immunization strategy. The fund is currently short 254 contracts based on a 10-year bond with a par value of EUR 100,000 and a basis point value (BPV) of EUR 97.40 per contract.
Given the futures position entered into by the pension fund, Ruelas most likely believes interest rates will:
选项：
A.fall. B.rise.
remain the same.
解释：
A is correct. The number of futures contracts needed to fully remove the duration gap between the asset and liability portfolios is given by Nf = (BPVL – BPVA)/BPVf, where BPV is basis point value (of the liability portfolio, asset portfolio, and futures contract, respectively). In this case, Nf = (59,598 – 91,632)/97.4 = –328.891, where the minus sign indicates a short position or selling of 329 futures contracts (328,891/1,000). Ruelas has under-hedged, leaving a net position that will benefit from a reduction in interest rates, just as the unhedged position would benefit from a reduction in interest rates. Thus, he must believe interest rates will fall.
B is incorrect because if Ruelas believed rates would rise, he would under-hedge, leaving a net position that would benefit from rising rates.
C is incorrect because if Ruelas believed rates wouldn’t change, he would hedge fully, in case rates moved in an unexpected way.
这是本次复习第二遍做这题，又错了。我想不通为什么只要通过derivative overlay后，BPV asset＞BPV liability，就是预期利率下降？
我的思路是利率下降，资产价格应该上升，但如果asset money duration >liabiliy money duration ,asset portfolio value 会更高，liabiliy value会更低，这样不久mismatch 了么? 难道就是为了创造出更多的surplus?
