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. An analyst takes a sample of five firms in the footwear industry and records their P/E ratios as: 26, 13, 21, 16, and 21.(You may find it useful to reference thettable.)
