Imagine you're researching Downsizers Diet Centers Inc. (ticker: SLIMM), and you read that "it deserves to trade at 28 times trailing earnings, or about $56 today. If it maintains 18% earnings per share (EPS) growth, it appears to be a bargain right now." You were doing fine until you got this far, but now you're flummoxed. The concepts involved are simple and valuable, though, so let's clear them up.
The word "multiple" usually refers to a company's P/E, or price-to-earnings, ratio, which is its current stock price divided by its earnings per share. If a company has a P/E of 28, people will say that it's trading at "28 times earnings" or at "a multiple of 28." (Learn more about the P/E ratio here.)
Savvy Fools often examine a company's multiple and compare it with what seems to be a fair multiple, given the company's industry and competitive position. Let's say that Downsizers' peers all have multiples in the high 30s and its own multiple is in the low 20s. A low multiple can be promising, since it suggests that the stock is undervalued and that the price will increase as the multiple catches up to those of its peers. (It can also indicate that the company is losing in the marketplace or has other problems, though.)
Briskly growing earnings are also auspicious. Earnings growth drives stock-price growth, and rapid growth can even make up for a relatively high multiple. How fast earnings grow is also a good indicator of how high a company's P/E should be. In other words, a company doubling its earnings every year deserves a higher P/E (or multiple) than does a company growing gradually.
Expected earnings growth coupled with P/E-multiple growth can offer a powerful one-two punch. (Warning: Numbers ahead!) Imagine a stock trading at $10 per share -- 10 times its EPS of $1. As earnings grow, the stock price will likely increase to maintain the multiple. For example, when earnings are $2 per share, the stock price should be near $20. But if the multiple is also growing, the price is likely to increase even more. If a reasonable multiple is perceived to be more like 15 and the earnings are $2 per share, the stock should eventually approach $30 per share. Companies generating above-average earnings growth and trading at below-average P/E ratios can make for great investments.
Here are recent P/E ratios, or multiples, for a few stocks in similar industries:
| Company | P/E |
|---|---|
| Apple (NASDAQ:AAPL) | 39 |
| Dell (NASDAQ:DELL) | 28 |
| Procter & Gamble (NYSE:PG) | 21 |
| Clorox (NYSE:CLX) | 20 |
| Amazon (NASDAQ:AMZN) | 35 |
| eBay (NASDAQ:EBAY) | 58 |
Finally, understand that there are other kinds of multiples. If you read analyses of various companies, you'll see references to price-to-sales multiples, book value multiples, cash flow multiples, and more. It's instructive to compare a company's various multiples with those of its competitors.
