Do you follow value investors such as Warren Buffett? This type of investing involves searching for stocks that appear to be trading at a price below their fair value. Investors that are keen enough to spot these opportunities will benefit as the stock rises to converge with its fair value.

For ideas on how to start your own value investing screen, we screened for stocks that appear undervalued relative to the Graham Number, a measure of a stock's maximum fair value created by the "Godfather of value investing" Benjamin Graham. The number is based on a stock's EPS and book value per share (BVPS).

Graham Number = SQRT(22.5 x TTM EPS x MRQ BVPS)

The equation assumes that P/E should not be higher than 15 and P/BV should not be higher than 1.5. Stocks trading well below their Graham Number may be undervalued.

Finally, we searched among the potentially undervalued stocks for those nearing their 52-week high. This may seem contradictory -- these names seem on their way to closing the gap between market value and "fair value" -- but it's very possible they have more upside to price in.

Trading near a 52-week high indicates the firm has strong upward momentum. The fact that they still appear undervalued despite hitting new highs suggest ample opportunity to continue their rally.
