Not every year yields positive stock market returns, and at times, an entire year’s return can be reversed in a matter of months. So you’ll generally see variances in implied volatility at different strike prices and expiration months. For example, imagine stock XYZ is trading at $50, and the implied volatility of an option contract is 20%. This implies there’s a consensus in the marketplace that a one standard deviation move over the next 12 months will be plus or minus $10 (since 20% of the $50 stock price equals $10).

Market volatility measures the frequency and magnitude of movements in asset prices – i.e. the size and rate of “swing-like” fluctuations. It is used to predict the future movements of prices based on previous trends. However, it does not provide insights regarding the future trend or direction of the security’s price. Volatility is determined either by using the standard deviation or beta.
