“Forecast Volatility—One of the four basic interpretations of volatility. A prediction, or 'best guess,' regarding the degree of price movement, or volatility, that can be expected for a given security in the future. With respect to derivative securities, such as options, forecast volatility usually relates to the predicted price movements of the underlying asset rather than of the option itself.
“预期波动率—波动率的四种基本理解之一，对给定有价证券未来价格变化幅度（或波动率）的预测，或“最好预测”。对于衍生证券，比如期权，预期波动率通常预测标的资产价格变化而非期权本身。
