About Graham-Dodd stock screener

Security Analysis is arguably the most important book on value investing. You might be surprised, but there is no valuation methodology in the book. Benjamin Graham and David Dodd did not provide any indication that they used a formula or a specific algorithm for determining intrinsic value of common stocks.

The book, quite appropriately, is named "Security Analysis", not "Security Valuation". In the sections related to common-stock investment, it contains description of a general approach to selecting stocks. There is also a good treatise on how to adjust the income statement and balance sheet and what factors to look at in a comparison valuation. But you will be looking in vain for a well defined valuation process. Nonetheless, Security Analysis is a great book. It clearly distinguishes investing from speculation, and arms the investor with general guiding principles of investing.

The stock screener presented here is not the one used by the founders of the security analysis, but the one developed by us using the general approach to security valuation they employed. The stock screener compares intrinsic value of a stock with its current market price. The difference between them is called the margin of safety.
