答案:A

解析:

2005年5月的案例里,策略為short the protection of equity tranch of CDO(賣出equity CDS,收保費(fèi)spread)、long the protection of mezzanine tranch(買入mezzanine保險(xiǎn),付spread),由于equity tranch of CDO風(fēng)險(xiǎn)更大,故收的保費(fèi)比付的保費(fèi)多從而獲利,但zui終因?yàn)棣呀档投鴵p失。【資料下載】GARP協(xié)會(huì)《2021年FRM學(xué)習(xí)目標(biāo)》

當(dāng)ρ接近于1時(shí),equity和mezzanine可能同時(shí)違約或不違約,與mezzanine共進(jìn)退,對(duì)equity來說,價(jià)值是上升的,而mezzanine價(jià)值下降。

當(dāng)ρ下降時(shí),equity的價(jià)值下降,風(fēng)險(xiǎn)上升,保費(fèi)上升,而策略里收的保費(fèi)是固定好的,故虧損;mezzanine價(jià)值上升,風(fēng)險(xiǎn)下降,保費(fèi)下降,而策略里支付的保費(fèi)是固定的,故虧損;在此題中,是賣出senior的保護(hù),所以相反。
