We have decommissioned the IOI Tools site and replaced them with two downloadable spreadsheets. The IOI Valuation Model allows you to model the main drivers of value as discussed in The Intelligent Option Investor. The BSM Cone Tool allows you to download stock price data for U.S.-listed companies and input implied volatility and valuation range data to create a BSM Cone.
