Volatility is a measure for variation of price of a Volatility financial instrument over time. Historical volatility is a direct measure of the volatility movement of the underlying price (realized volatility) over recent history (e. g. a trailing 21 -day period). An implied volatility is derived from the market volatility price of a market traded derivative (in particular an option)
¡ For instance, the IBM call option, struck at $100 and expiring in 6 months, may have an implied volatility of 18%, ¡ While the put option struck at $105 and expiring in 1 month may have an implied volatility of 21%. ¡ At the same time, the historical volatility for IBM for the previous 21 day period might be 17% (all volatilities are expressed in annualized percentage moves).
¡ Implied volatilities often exceed their historic counterparts prior to a major announcement (such as an earnings announcement or a merger), and tend to the mean afterwards. ¡ For example, if the market is enthusiastic about a specific stock (perhaps due to a great earnings report), then a call option will be expensive. Accordingly, a covered call is a good strategy.
Implied volatility as measure of relative value EX: A call option is trading at $1. 50 with the underlying trading at $42. 05. The implied volatility of the option is determined to be 18. 0%. A short time later, the option is trading at $2. 10 with the underlying at $43. 34, yielding an implied volatility of 17. 2%.
