Frequently Asked Questions
What is the Graham Number formula?
Graham Number = the square root of (22.5 x EPS x Book Value per Share). Benjamin Graham derived 22.5 from his rule that a stocks P/E ratio should not exceed 15 and its P/B ratio should not exceed 1.5 (15 x 1.5 = 22.5).
What does it mean if a stock trades below its Graham Number?
A stock trading below its Graham Number may be undervalued by Grahams conservative criteria, though this is only one of many valuation signals and should not be used alone.
