With a price-to-earnings (or "P/E") ratio of 20.1x Dover Corporation (NYSE:DOV) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 16x and even P/E's lower than 8x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

While the market has experienced earnings growth lately, Dover's earnings have gone into reverse gear, which is not great. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

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

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 9.8%. Still, the latest three year period has seen an excellent 58% overall rise in EPS, in spite of its unsatisfying short-term performance. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 11% during the coming year according to the analysts following the company. That's shaping up to be similar to the 10% growth forecast for the broader market.

With this information, we find it interesting that Dover is trading at a high P/E compared to the market. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

What We Can Learn From Dover's P/E?

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Dover currently trades on a higher than expected P/E since its forecast growth is only in line with the wider market. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
