Historical Volatility data, Implied Volatility data, and the Current Implied Volatility Percentile for all stock, index and futures options updated weekly.
One of most important things an option trader watches is volatility. The daily Volatility History report in The Strategy Zone offers you the data you need to be a well-prepared option trader: three historical volatility levels, plus implied volatility, and the percentile of implied volatility. Each Saturday, the weekly data is available for you here at no cost (see below).
Volatility is measured in standard deviations, but that is a term that is foreign to most people, and even a statistician would have trouble putting it into words that everyone could understand. So the volatility figures shown in this report are best used as comparative measures. That is, if we know IBM has a volatility of 20% and Sears Holdings has a volatility 60%, then we know that SHLD is much more volatile than IBM – about three times as volatile.
