Price earnings multiple definition

What is the Price Earnings Multiple?

The price earnings multiple compares the earnings per share reported by a company to the market price of its common stock. This multiple is used by investors to judge how expensive a share of the company's stock is. During a declining market, the overall price earnings multiples tend to decline for the shares of all companies, with the reverse occurring when the economy is expanding.

When the Price Earnings Multiple Increases

Investors tend to bid up share prices, which increases the price earnings multiple, when there is an expectation of greater earnings in the future, even if the issuing entity is not currently reporting increased earnings per share. This can occur when a promising new product or service is released or announced. The multiple may also increase when the reported earnings per share exceed the expectations of analysts.

When the Price Earning Multiple Decreases

The multiple is more likely to decline under any situation where there is an indication that a firm’s future earnings per share will decrease. For example, a business predicts disappointing earnings in its most recent earnings conference call. Or, a competitor releases a product that will directly compete with the company’s products; a future earnings decline is therefore to be expected. As another example, the trade barriers with another country are removed, which increases the risk of price competition. Or, a lawsuit with a potentially large payout is filed against the company. And as a final example, the government approves new regulations that will harm the firm’s operations. In all of these scenarios, investors are likely to conclude that a firm’s earnings will be depressed, and so bid down the price of its stock. The result is a decrease in the company’s price earnings multiple.
