Implied volatility is calculated by taking the market price of the option, entering it into the Black-Scholes formula, and back-solving for the value of the volatility.
How do you find the historical implied volatility of a stock?
Calculating Volatility
- Collect the historical prices for the asset.
- Compute the expected price (mean) of the historical prices.
- Work out the difference between the average price and each price in the series.
- Square the differences from the previous step.
- Determine the sum of the squared differences.

What is implied volatility and how is it calculated?
Typically implied volatility is calculated by taking the price of an option (usually the mid-price) and entering it into a pricing model, such as Black-Scholes. Implied volatility is less a calculation and more the result of observations of option volatility, or a volatility index, such as the Cboe Global Markets Volatility Index (VIX).
What does the Vix tell us about volatility?
The VIX intends to reflect the current estimate of expected volatility and typically closes at a price that is higher than the subsequent 30-calendar-day (21-trading-day) realized volatility. Since 1990, the average spread between the VIX and the realized volatility of the S&P 500 Index was positive with one exception—2008.
What is the CBOE Volatility Index?
The CBOE Volatility Index (VIX) is an important measure for market volatility. The VIX shows 30-day implied volatility based on S&P 500 index option prices.

How can I gain exposure to the volatility of the underlying?
Other things being equal, options struck on an equity index with higher expected volatility will be more valuable than options struck on an index expected to be less volatile. Options, therefore, are a simple way to gain exposure to the volatility of the underlying.
