Do you prefer stocks that pay dividends you can rely on? We ran a screen with this idea in mind.

We began by screening the S&P 500 for dividend stocks: those paying dividend yields above 2% and sustainable payout ratios below 50%.

Then we screened that universe for those that 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.
