Ducommun Incorporated's (NYSE:DCO) price-to-earnings (or "P/E") ratio of 49x 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 9x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Recent times haven't been advantageous for Ducommun as its earnings have been falling quicker than most other companies. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Ducommun's Growth Trending?

Ducommun's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much 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 51%. The last three years don't look nice either as the company has shrunk EPS by 56% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 65% during the coming year according to the five analysts following the company. With the market only predicted to deliver 11%, the company is positioned for a stronger earnings result.

In light of this, it's understandable that Ducommun'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.
