A Sliding Share Price Has Us Looking At Ducommun Incorporated's (NYSE:DCO) P/E Ratio

Unfortunately for some shareholders, the Ducommun (NYSE:DCO) share price has dived 43% in the last thirty days. That drop has capped off a tough year for shareholders, with the share price down 41% in that time.

Assuming nothing else has changed, a lower share price makes a stock more attractive to potential buyers. In the long term, share prices tend to follow earnings per share, but in the short term prices bounce around in response to short term factors (which are not always obvious). The implication here is that long term investors have an opportunity when expectations of a company are too low. One way to gauge market expectations of a stock is to look at its Price to Earnings Ratio (PE Ratio). A high P/E implies that investors have high expectations of what a company can achieve compared to a company with a low P/E ratio.

Does Ducommun Have A Relatively High Or Low P/E For Its Industry?

We can tell from its P/E ratio of 9.08 that sentiment around Ducommun isn't particularly high. The image below shows that Ducommun has a lower P/E than the average (15.4) P/E for companies in the aerospace & defense industry.

This suggests that market participants think Ducommun will underperform other companies in its industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

In the last year, Ducommun grew EPS like Taylor Swift grew her fan base back in 2010; the 255% gain was both fast and well deserved. Having said that, if we look back three years, EPS growth has averaged a comparatively less impressive 7.6%.

Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

Don't forget that the P/E ratio considers market capitalization. So it won't reflect the advantage of cash, or disadvantage of debt. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

How Does Ducommun's Debt Impact Its P/E Ratio?

Ducommun's net debt is 90% of its market cap. If you want to compare its P/E ratio to other companies, you should absolutely keep in mind it has significant borrowings.

The Bottom Line On Ducommun's P/E Ratio

Ducommun has a P/E of 9.1. That's below the average in the US market, which is 13.4. The company may have significant debt, but EPS growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified. What can be absolutely certain is that the market has become more pessimistic about Ducommun over the last month, with the P/E ratio falling from 15.9 back then to 9.1 today. For those who prefer invest in growth, this stock apparently offers limited promise, but the deep value investors may find the pessimism around this stock enticing.
