The Graham Number is considered to be the maximum price an investor should pay for a stock, according to the formula developed by Benjamin Graham.

It is calculated as follows:

- Graham Number = Square Root of (22.5) x (Earnings per Share) x (Book Value per Share).

This equation is predicated on Graham’s 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 included companies that meet both of these criteria. As a result, 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. After taking the square root of both sides, the equation emerges...

We also created a price-weighted index of the stocks mentioned below, and monitored the performance of the list relative to the S&P 500 index over the last month. To access a complete analysis of this list's recent performance, click here.
