In the search for potentially undervalued stocks, one method comes from the “godfather of value investing,” Benjamin Graham. Graham was an author, professor and former mentor of 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.
Using this equation, we screened for potentially undervalued stocks among the universe of stocks trading under $3.
