Below we present nine utilities stocks with dividends between 4%-7%. These stocks are also undervalued by the Graham Number. *Click for expanded images*

Benjamin Graham, the man who developed this equation, was a former mentor of Warren Buffett and is the so-called “Godfather” of value investing.

The Graham Number, or the maximum price an investor should pay for a stock, is derived using only two data points: Current earnings per share and current book value per share.

The Graham Number = Fair Value of a Stock = Square Root of (22.5) x (TTM Earnings per Share) x (MRQ Book Value per Share).

The math of the Graham number is relatively straightforward. It is predicated on the belief that the price-to-earnings (P/EPS) ratio should be no more than 15, and the price-to-book value (P/BVPS) ratio should be no more than 1.5. Therefore we only include companies that meet both of these criteria.

From these criteria, the product of the two should not be more than 22.5. In other words, (P/EPS of 15) x (P/BVPS of 1.5) = 22.5, from which the equation was created.
