ILE A research analyst is trying to determine whether a firm's price-earnings (P/E) and price-sales (P/S) ratios can explain the firm's stock performance over the past year. A 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 P/S ratio is calculated by dividing a firm's share price by the firm's revenue per share for the trailing 12 months. In short, investors can use the P/S ratio to determine how much they are paying for a dollar of the firm's sales rather than a dollar of its earnings (P/E ratio). In general, the lower the P/S ratio, the more attractive the investment. The accompanying table shows the year-to-date (YTD) returns and the P/E and P/S ratios for a portion of the 30 firms included in the Dow Jones Industrial Average. The complete data set can be found on the text website, labeled Dow 2010.
