implied volatility

基本解釋

Only rarely, as on February 27th, does the curve “invert” so that short-term implied volatility is higher than long-term.
僅在很少情況下，如2月27日，市場曲線發(fā)生倒轉(zhuǎn)因此短期隱含波動高于長期隱含波動。
In quiet markets, the number of people who want to sell options increases, driving their prices, and thus the level of implied volatility, down.
在市場平靜的時候，愿意出售期權(quán)的人增加，使它們的價格，也就是隱含波動性的等級下降。
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.
對處于價外狀態(tài)的期權(quán)而言，投資者已樂意為此支付比那些承保小幅下跌的合約更高的價格（以隱含波動為衡量標準）。
