kaplan notes 第五冊(cè) P36,第4題, the put-call-forward parity relationship least likely includes A a risk-free bond B call and put options C the underlying asset 為什么選C
kaplan notes中第五冊(cè),P22頁(yè),derivatives pricing models use the risk-free rate to discount future cash flows because these models A are based on portfolios with certain payoffs B assume that derivatives investors are risk-neutral. C assume that risk can be eliminated by diversification. 為什么答案是A,不是B 呢?

老師您好!B選項(xiàng)還是有點(diǎn)不太理解。根據(jù)遠(yuǎn)期合約pricing的通式FP=(S0+PVC0-PVB0)*(1+Rf)^T. 在對(duì)遠(yuǎn)期合約定價(jià)(即未來(lái)合約到期時(shí)標(biāo)的資產(chǎn)的價(jià)格)時(shí),并沒(méi)有涉及到用無(wú)風(fēng)險(xiǎn)利率折現(xiàn)???我的理解是,折現(xiàn)肯定是未來(lái)的價(jià)格折到現(xiàn)在時(shí)點(diǎn)的價(jià)格,但在對(duì)遠(yuǎn)期合約定價(jià)時(shí),是以現(xiàn)在0時(shí)點(diǎn)的價(jià)格計(jì)算未來(lái)到期日的價(jià)格,不存在所謂discounting的過(guò)程啊。不過(guò)在valuation過(guò)程中,會(huì)有對(duì)FP/(1+Rf)^T-t的折現(xiàn)過(guò)程。
