The Graham number or Benjamin Graham number is a figure used in securities investing that measures a stock's so-called fair value. Named after Benjamin Graham, the founder of value investing, the Graham number can be calculated as follows: The final number is, theoretically, the maximum price that a defensive investor should pay for the given stock. Put another way, a stock priced below the Graham Number would be considered a good value, if it also meets a number of other criteria. The Number represents the geometric mean of the maximum that one would pay based on earnings and based on book value. Graham writes: Current price should not be more than 11⁄2 times the book value last reported. However a multiplier of earnings below 15 could justify a correspondingly higher multiplier of assets. As a rule of thumb we suggest that the product of the multiplier times the ratio of price to book value should not exceed 22.5. (This figure corresponds to 15 times earnings and 11⁄2 times book value. It would admit an issue selling at only 9 times earnings and 2.5 times asset value, etc.) — Benjamin Graham, The Intelligent Investor, chapter 14 (Wikipedia).
