PEG Ratio (Price/Earnings to Growth Ratio)

The PEG ratio (Price/Earnings to Growth ratio) is a valuation metric that compares a stock’s price-to-earnings (P/E) ratio to its expected earnings growth rate. It is calculated by dividing the P/E ratio by the annual earnings growth rate. A PEG ratio of 1 suggests that a stock’s price is fairly valued relative to its growth rate, while a PEG ratio below 1 may indicate an undervalued stock. The PEG ratio provides a more complete picture than the P/E ratio alone, as it considers a company’s growth potential.

Example

A stock with a P/E ratio of 20 and an expected earnings growth rate of 10% has a PEG ratio of 2, indicating it may be overvalued relative to its growth.

Key points

• Measures a stock’s valuation by comparing its P/E ratio to its expected growth rate.

• A PEG ratio of 1 suggests fair valuation; below 1 may indicate undervaluation.

• Offers a more comprehensive view than the P/E ratio by factoring in growth.

Quick Answers to Curious Questions
