A common measure for identifying undervalued and overvalued stock. It uses the relationship between a company’s earnings and share price to value a company’s stock. The P/E ratio is calculated by dividing the current market price per share by the earnings per share. A stock’s P/E ratio gives you a sense of what you are paying for a stock in relation to its earning power (e.g., a stock with a P/E of 20 is trading at 20 times its earnings). If a company’s market price is $40 and the earnings per share is $4, the P/E ratio for the company is 10.
