SkyWest, Inc.'s (NASDAQ:SKYW) price-to-earnings (or "P/E") ratio of 9x might make it look like a strong buy right now compared to the market in the United States, where around half of the companies have P/E ratios above 20x and even P/E's above 35x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

SkyWest certainly has been doing a good job lately as it's been growing earnings more than most other companies. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

There's an inherent assumption that a company should far underperform the market for P/E ratios like SkyWest's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 79% gain to the company's bottom line. Pleasingly, EPS has also lifted 340% in aggregate from three years ago, thanks to the last 12 months of growth. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Turning to the outlook, the next year should generate growth of 1.1% as estimated by the six analysts watching the company. With the market predicted to deliver 16% growth , the company is positioned for a weaker earnings result.

With this information, we can see why SkyWest is trading at a P/E lower than the market. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.

The Final Word

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

As we suspected, our examination of SkyWest's analyst forecasts revealed that its inferior earnings outlook is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.

Of course, you might also be able to find a better stock than SkyWest. So you may wish to see this free collection of other companies that have reasonable P/E ratios and have grown earnings strongly.
