If you’re looking for ideas on how to search for potentially undervalued stocks, one method comes from the “godfather of value investing” himself, Benjamin Graham. Graham was an author, professor, and former mentor to Warren Buffett.

Graham created an equation that calculates the fair value of stocks based on two fundamental data points: current earnings per share and current book value per share.  The Graham Number = Square Root of (22.5) x (TTM Earnings per Share) x (MRQ Book Value per Share).   This equation assumes that a stock is overvalued if P/E is over 15 or P/BV is over 1.5.

Stocks trading at significant discounts to this number appear undervalued.

We ran a screen on stocks in the clean energy industry for those trading at significant discounts to their Graham numbers, appearing undervalued.
