With a price-to-earnings (or "P/E") ratio of 30.2x Landstar System, Inc. (NASDAQ:LSTR) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 18x and even P/E's lower than 10x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Landstar System has been struggling lately as its earnings have declined faster than most other companies. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Landstar System's Growth Trending?

In order to justify its P/E ratio, Landstar System would need to produce outstanding growth well in excess of the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 35%. The last three years don't look nice either as the company has shrunk EPS by 20% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Turning to the outlook, the next three years should generate growth of 14% per year as estimated by the analysts watching the company. That's shaping up to be materially higher than the 10% each year growth forecast for the broader market.

With this information, we can see why Landstar System is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Final Word

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

As we suspected, our examination of Landstar System's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. Right now shareholders are comfortable with the P/E as they are quite confident future earnings aren't under threat. It's hard to see the share price falling strongly in the near future under these circumstances.
