One helpful way to find potentially undervalued firms is from the “godfather of value investing” himself, Benjamin Graham.

Graham created an equation to calculate the maximum fair value for a stock, referred to as the Graham Number. Any stock trading at a significant discount to this number would appear undervalued.

The Graham Number only requires two 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.

We used the Graham equation to screen for potentially undervalued stocks among those rallying above their 20-day, 50-day, and 200-day moving averages. From this universe, we then searched for those seeing significant net insider buying over the last six months.
