PEG ratio

The 'PEG ratio' (price/earnings to growth ratio) is a valuation metric for determining the relative trade-off between the price of a stock, the earnings generated per share (EPS), and the company's expected growth. The 'PEG ratio' (price/earnings to growth ratio) is a valuation metric for determining the relative trade-off between the price of a stock, the earnings generated per share (EPS), and the company's expected growth. In general, the P/E ratio is higher for a company with a higher growth rate. Thus, using just the P/E ratio would make high-growth companies appear overvalued relative to others. It is assumed that by dividing the P/E ratio by the earnings growth rate, the resulting ratio is better for comparing companies with different growth rates. The PEG ratio is considered to be a convenient approximation. It was originally developed by Mario Farina who wrote about it in his 1969 Book, A Beginner's Guide To Successful Investing In The Stock Market. It was later popularized by Peter Lynch, who wrote in his 1989 book One Up on Wall Street that 'The P/E ratio of any company that's fairly priced will equal its growth rate', i.e., a fairly valued company will have its PEG equal to 1. PEG Ratio = Price/Earnings Annual EPS Growth {displaystyle {mbox{PEG Ratio}},=,{frac {mbox{Price/Earnings}}{mbox{Annual EPS Growth}}}} The growth rate is expressed as a percent value, and should use real growth only, to correct for inflation. E.g. if a company is growing at 30% a year, in real terms, and has a P/E of 30, it would have a PEG of 1.
