Price-to-Earnings Ratio (P/E), Explained Simply
P/E tells you what you pay per dollar of profit. Here's how to read it in plain English.
The price-to-earnings ratio, or P/E, tells you how much you are paying for every dollar of a company's yearly profit.
You take the price of one share and divide it by the company's earnings per share over the past year. The result is a single number that shows how expensive or cheap a stock is compared to what the company actually earns.
Here is why it matters. A high P/E means investors are paying a premium, often because they expect big growth ahead. A low P/E can mean a bargain, or it can mean folks have doubts about the company's future. The number only means something when you compare it to similar companies or to the same company's own history.
Let's use real dollars. A stock trades at $100 a share and the company earned $5 per share last year. That is a P/E of 20 ($100 divided by $5). In plain terms, you are paying $20 for each $1 of yearly profit. A competitor at a P/E of 10 would be half as pricey per dollar earned.
Bottom line: P/E is a quick gut-check on whether a stock is cheap or expensive relative to its profits, but one number never tells the whole story.
