Price Earning Ratio

The price-to-earnings ratio is the ratio for valuing a company that measures its current share price relative to its earnings per share (EPS). The price-to-earnings ratio is also sometimes known as the price multiple or the earnings multiple.

P/E ratios are used by investors and analysts to determine the relative value of a company's shares in an apples-to-apples comparison to others in the same sector. It can also be used to compare a company against its own historical record or to compare aggregate markets against one another or over time. To determine the P/E value, one must simply divide the current stock price by the earnings per share (EPS). The current stock price (P) can be found simply by plugging a stock’s ticker symbol into any finance website, and although this concrete value reflects what investors must currently pay for a stock, the EPS is a slightly more nebulous figure.
