PC Connection, Inc.'s (NASDAQ:CNXN) price-to-earnings (or "P/E") ratio of 22.3x might make it look like a sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 17x and even P/E's below 10x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

PC Connection certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. 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.

What Are Growth Metrics Telling Us About The High P/E?

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

Retrospectively, the last year delivered an exceptional 17% gain to the company's bottom line. The latest three year period has also seen an excellent 45% overall rise in EPS, aided by its short-term performance. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Looking ahead now, EPS is anticipated to climb by 8.6% during the coming year according to the two analysts following the company. Meanwhile, the rest of the market is forecast to expand by 14%, which is noticeably more attractive.

In light of this, it's alarming that PC Connection's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. 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 growth outlook.

The Bottom Line On PC Connection's P/E

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that PC Connection currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
