With a price-to-earnings (or "P/E") ratio of 37.5x ICON Public Limited Company (NASDAQ:ICLR) 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.

With its earnings growth in positive territory compared to the declining earnings of most other companies, ICON has been doing quite well of late. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For ICON?

ICON's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 39%. EPS has also lifted 25% in aggregate from three years ago, mostly thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been respectable for the company.

Turning to the outlook, the next three years should generate growth of 20% per annum as estimated by the analysts watching the company. That's shaping up to be materially higher than the 10% per annum growth forecast for the broader market.

With this information, we can see why ICON is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Key Takeaway

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

As we suspected, our examination of ICON'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.
