Graham Number

Benjamin Graham, known as the "Father of Value Investing," invented the Graham number. This value is used to determine the stock's fair value in securities investment. It's calculated by taking the financial figures of Earnings Per Share and Book Value Per Share (BVPS).Theoretically the Graham number represents the highest price a defensive investor should pay for a stock. It is deemed beneficial if the stock price is less than the Graham Number. As per Graham's philosophy, companies can uncover undervalued prospects by thoroughly reviewing their financial statements.

The formula to derive Graham Number

Graham Number

Example: GAIL (India) Ltd. reported EPS as Rs. 21.08 and BVPS (Book Value Per Share) of Rs. 119.99.
The value as per the formula [( √15 x 1.5 x EPS TTM x BVPS) or ( √22.5 x EPS TTM x BVPS)] is calculated as (√15 x 1.5 x 13.82 x 119.99) = 238.56

Gail India Limited is currently trading at a lower price than Graham Number. So as per Graham Number, it indicates that it is undervalued.

If a company's Price to Earnings (PE) ratio is under 15 and its Price to Book (PB) ratio is under 1.5, then the Graham number is effective. And if a company's price to earning ratio is above 15 and its price to book ratio above 1.5 then the graham number may not be that effective. Hence ben graham took pe ratio 15 and pb ratio 1.5 in his graham number formula.

Price to Graham Number

He has led a current wave of value investing in hedge funds, diversified holding companies, mutual funds, and other ventures through his work in management economics and investing. He accomplished it by receiving the title of Salutatorian from Columbia University when he was 20 years old, a distinction given to the second-ranked graduate of all graduates in the United States. Because of his outstanding performance, he was given a position as a faculty member at Columbia University, where he would teach Mathematics, English, and Philosophy. On the other hand, he wanted to work for a Wall Street brokerage company called Newburger, Henderson & Loeb.

Stocks of companies that trade at a higher price than a Graham Number are considered overvalued as per the Graham number.
