CAST.ST Fair Value - Formula's Origin

Peter Lynch is one of the most legendary investors/fund managers of all time. His philosophy for stock investing is very simple and straightforward: he invests in stocks that are undervalued, meaning its P/E is less than or equal to its earnings growth rate. He believes that if a stock is trading at its fair value, the PEG ratio, which was also invented by him, should be 1.

Therefore, his formula to determine a company's fair value is:

Peter Lynch Fair Value = Earnings Growth Rate * EPS * PEG

PEG is set to 1 so we can ignore it in the calculation. Based on the formula, if the earnings growth rate of a company is 15%, Peter Lynch is willing to buy its share up to P/E = 15.
