In quiet markets, the number of people who want to sell options increases, driving their prices, and thus the level of implied volatility, down.
在市場(chǎng)平靜的時(shí)候，願(yuàn)意出售期權(quán)的人增加，使它們的價(jià)格，也就是隱含波動(dòng)性的等級(jí)下降。
They have been willing to pay a higher price (as measured by implied volatility) for extreme out-of-the-money options than for contracts that insure against smaller market declines.
對(duì)処於價(jià)外狀態(tài)的期權(quán)而言，投資者已樂意爲(wèi)此支付比那些承保小幅下跌的郃約更高的價(jià)格（以隱含波動(dòng)爲(wèi)衡量標(biāo)準(zhǔn)）。
