Are you a value investor, always looking for potentially undervalued names? We ran a screen with that idea in mind.

We began by screening the industrial goods sector for stocks that appear undervalued relative to earnings growth, with PEG below 1.

We then screened for those that also appear undervalued relative to the Graham Number. The Graham Number is a measure of maximum fair value created by the "godfather of value investing" Benjamin Graham.

It is based off of 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.
