Diodes Incorporated's (NASDAQ:DIOD) Business Is Trailing The Market But Its Shares Aren't

With a median price-to-earnings (or "P/E") ratio of close to 17x in the United States, you could be forgiven for feeling indifferent about Diodes Incorporated's (NASDAQ:DIOD) P/E ratio of 15x. 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.

Recent times haven't been advantageous for Diodes as its earnings have been falling quicker than most other companies. One possibility is that the P/E is moderate because investors think the company's earnings trend will eventually fall in line with most others in the market. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. Or at the very least, you'd be hoping it doesn't keep underperforming if your plan is to pick up some stock while it's not in favour.

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

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

Retrospectively, the last year delivered a frustrating 32% decrease to the company's bottom line. Even so, admirably EPS has lifted 156% in aggregate from three years ago, notwithstanding the last 12 months. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Shifting to the future, estimates from the seven analysts covering the company suggest earnings growth is heading into negative territory, declining 3.0% each year over the next three years. That's not great when the rest of the market is expected to grow by 11% per year.

With this information, we find it concerning that Diodes is trading at a fairly similar P/E to the market. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock right now. 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.
