It's not a stretch to say that Grand Canyon Education, Inc.'s (NASDAQ:LOPE) price-to-earnings (or "P/E") ratio of 18.9x right now seems quite "middle-of-the-road" compared to the market in the United States, where the median P/E ratio is around 18x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Grand Canyon Education has been doing quite well of late. It might be that many expect the strong earnings performance to deteriorate like the rest, which has kept the P/E from rising. If not, then existing shareholders have reason to be feeling optimistic about the future direction of the share price.

Is There Some Growth For Grand Canyon Education?

There's an inherent assumption that a company should be matching the market for P/E ratios like Grand Canyon Education's to be considered reasonable.

Taking a look back first, we see that the company grew earnings per share by an impressive 20% last year. The latest three year period has also seen an excellent 31% overall rise in EPS, aided by its short-term performance. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Turning to the outlook, the next year should generate growth of 9.7% as estimated by the three analysts watching the company. Meanwhile, the rest of the market is forecast to expand by 15%, which is noticeably more attractive.

In light of this, it's curious that Grand Canyon Education's P/E sits in line with the majority of other companies. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.

What We Can Learn From Grand Canyon Education's P/E?

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.

When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower.
