The following is a list of tech stocks that are undervalued when comparing the current price to the fair value price, calculated by the Graham Number equation.

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 (Earnings per Share) x (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.

Do you think these companies could be undervalued? Full details below.
