Don't be put off by the algebraic formulas that follow. They're included to justify the result. In the end, all you'll have to do is look up implied growth on Table 5-1. Graham and Dodd defined intrinsic value as:
Intrinsic Value = Eps x [8.5 + (2 x forecast annual earnings growth %)]
(where Eps is the TTM earnings per share)
Put into words, Graham said that a company's intrinsic value is its latest annual earnings multiplied by a factor ...
