It's not a stretch to say that TriNet Group, Inc.'s (NYSE:TNET) price-to-earnings (or "P/E") ratio of 18x right now seems quite "middle-of-the-road" compared to the market in the United States, where the median P/E ratio is around 19x. 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.

While the market has experienced earnings growth lately, TriNet Group's earnings have gone into reverse gear, which is not great. One possibility is that the P/E is moderate because investors think this poor earnings performance will turn around. You'd really hope so, otherwise you're paying a relatively elevated price for a company with this sort of growth profile.

Does Growth Match The P/E?

The only time you'd be comfortable seeing a P/E like TriNet Group's is when the company's growth is tracking the market closely.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 12%. Regardless, EPS has managed to lift by a handy 19% in aggregate from three years ago, thanks to the earlier period of growth. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been mostly respectable for the company.

Looking ahead now, EPS is anticipated to slump, contracting by 20% during the coming year according to the five analysts following the company. Meanwhile, the broader market is forecast to expand by 15%, which paints a poor picture.

With this information, we find it concerning that TriNet Group is trading at a fairly similar P/E to the market. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. There's a good chance these shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the negative growth outlook.

The Key Takeaway

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.

We've established that TriNet Group currently trades on a higher than expected P/E for a company whose earnings are forecast to decline. When we see a poor outlook with earnings heading backwards, we suspect share price is at risk of declining, sending the moderate P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
