What is included in the Volatility Tool?
The Volatility Tool includes a rich Excel template with software to prevent user error and complete documentation. The Tool uses a mathematical formula to compare stock pricing action over annual periods to find the aggregate change in stock percentage (using a logarithm) and normalizing the changes over the trading days. See Item 4 below for more details. The Tool also includes extensive documentation. There are two versions: the Standard Edition which computes calendar year volatility and the Advanced Edition which computes volatility from user-specified dates. The Advanced Edition can also annualize partial year data (not available on the Standard Edition).
