implied volatility

基本解释

Only rarely, as on February 27th, does the curve “invert” so that short-term implied volatility is higher than long-term.
仅在很少情况下，如2月27日，市场曲线发生倒转因此短期隐含波动高于长期隐含波动。
In quiet markets, the number of people who want to sell options increases, driving their prices, and thus the level of implied volatility, down.
在市场平静的时候，愿意出售期权的人增加，使它们的价格，也就是隐含波动性的等级下降。
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.
对处于价外状态的期权而言，投资者已乐意为此支付比那些承保小幅下跌的合约更高的价格（以隐含波动为衡量标准）。
