同學(xué)你好。
當(dāng)我們?cè)谟懻摻档蚭quity 的敞口時(shí),有兩種方式。
1.以beta為目標(biāo)進(jìn)行調(diào)整(現(xiàn)金beta為0)(圖1)
2.以無(wú)風(fēng)險(xiǎn)資產(chǎn)為目標(biāo)進(jìn)行調(diào)整。(圖3)
一般來(lái)說(shuō),我們說(shuō)cash并不是指真正的現(xiàn)金,而是將其投資于短期的無(wú)風(fēng)險(xiǎn)資產(chǎn)。但是在這里,這道題目表述的不是很清楚,這里的cash到底是真正的現(xiàn)金還是指無(wú)風(fēng)險(xiǎn)資產(chǎn)。所以讓人有些迷惑,那我們是按照無(wú)風(fēng)險(xiǎn)資產(chǎn)來(lái)做的算出來(lái)是650,而可能這個(gè)章節(jié)的作者是按照真正的現(xiàn)金來(lái)理解的。在考試時(shí)會(huì)更嚴(yán)謹(jǐn),不會(huì)有歧義的。

追問(wèn)
老師您好,我問(wèn)的是這道題的B小題,在計(jì)算value of overall position時(shí),課后答案給出的是value of the stock portfolio+profit on the long futures position。難道不應(yīng)該是value of the stock portfolio+value of the long futures position嗎?:1. An investment management firm wishes to increase the beta for one of its portfolios under management from 0.95 to 1.20 for a three-month period. The portfolio has a market value of $175,000,000. The investment firm plans to use a futures contract priced at $105,790 in order to adjust the portfolio beta. The futures contract has a beta of 0.98. A. Calculate the number of futures contracts that should be bought or sold to achieve an increase in the portfolio beta. B. At the end of three months, the overall equity market is up 5.5 percent. The stock portfolio under management is up 5.1 percent. The futures contract is priced at $111,500. Calculate the value of the overall position and the effective beta of the portfolio.

同學(xué)你好,在計(jì)算組合價(jià)值變動(dòng)的時(shí)候,期貨部分代入計(jì)算的應(yīng)該是其profit 而不是期貨的價(jià)值。
期貨組合的價(jià)值變動(dòng)不應(yīng)該包含在計(jì)算中,因?yàn)槿ベI期貨的原因是希望調(diào)整beta來(lái)達(dá)到預(yù)期投資收益,它本身是作為工具,不應(yīng)該加入到組合價(jià)值的計(jì)算。
