Question

A price-earnings ratio or P/E ratio is calculated as a firm’s share price compared to the income or profit earned by the firm per share. Generally, a high P/E ratio suggests that investors are expecting higher earnings growth in the future compared to companies with a lower P/E ratio. The accompanying table shows the 26 companies that comprise the Dow Jones Industrial Average and their P/E ratios as of July 23, 2010 (at the time data were retrieved, data on four firms were not available).
