Do you consider yourself a value investor? If you prefer looking for stocks trading below their fair value, your answer is probably yes.

We ran a screen keeping value investing in mind, beginning with next week's roster of companies reporting their first-quarter earnings.

We then screened these names for those that are technically oversold, with Relative Strength Index readings over the last 14 days below 40. We also screened for those that appear undervalued relative to the Graham Number, 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.
