Arthur J. Gallagher & Co.'s (NYSE:AJG) price-to-earnings (or "P/E") ratio of 53.5x might make it look like a strong sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 16x and even P/E's below 10x are quite common. 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, Arthur J. Gallagher has been doing quite well of late. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is Arthur J. Gallagher's Growth Trending?

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

If we review the last year of earnings, the company posted a result that saw barely any deviation from a year ago. Regardless, EPS has managed to lift by a handy 14% in aggregate from three years ago, thanks to the earlier period of growth. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 23% per annum as estimated by the eight analysts watching the company. With the market only predicted to deliver 10% per year, the company is positioned for a stronger earnings result.

In light of this, it's understandable that Arthur J. Gallagher's P/E sits above the majority of other companies. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.
