Option Volatility

 variable in option pricing formulas showing the extent to which the return of the underlying asset will fluctuate between now and the options expiration. Volatility, as expressed as a percentage coefficient within option-pricing formulas, arises from daily trading activities
One of the most important steps in any option trade is to analyze implied volatility and historical volatility. This is the way option traders can gain edge in their trades. But analyzing implied volatility and historical volatility is an often-overlooked step, thus making some trades losers from the start.
Volatility changes can have a potential impact - good or bad - on any options trade you are preparing to implement. In addition to this so-called Vega risk/reward, this part of the options volatility tutorial will teach you about the relationship between historical volatility (also known as statistical, or SV) and implied volatility (IV),
Implied Volatility and Historical Volatility
Historical volatility (HV) is the volatility experienced by the underlying stock, stated in terms of annualized standard deviation as a percentage of the stock price. Historical volatility is helpful in comparing the volatility of a stock with another stock or to the stock itself over a period of time
In contrast to historical volatility, which looks at actual stock prices in the past, implied volatility (IV) looks forward. Implied volatility is often interpreted as the market’s expectation for the future volatility of a stock. Implied volatility can be derived from the price of an option. Specifically, implied volatility is the expected future volatility of the stock that is implied by the price of the stock’s options.
