Implied Volatility - Non-constant Implied Volatility

Non-constant Implied Volatility

In general, options based on the same underlying but with different strike values and expiration times will yield different implied volatilities. This is generally viewed as evidence that an underlying's volatility is not constant but instead depends on factors such as the price level of the underlying, the underlying's recent price variance, and the passage of time. See stochastic volatility and volatility smile for more information.

Famous quotes containing the word implied:

    Christianity as an organized religion has not always had a harmonious relationship with the family. Unlike Judaism, it kept almost no rituals that took place in private homes. The esteem that monasticism and priestly celibacy enjoyed implied a denigration of marriage and parenthood.
