Do you prefer stocks that offer both dividend income and the real possibility of capital gains? We ran a screen with that idea in mind.

We began by screening for high dividend yield stocks: those paying dividend yields above 4% and sustainable payout ratios below 50%.

We then 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.
