The Powell Industries, Inc. (NASDAQ:POWL) share price has softened a substantial 26% over the previous 30 days, handing back much of the gains the stock has made lately. The good news is that in the last year, the stock has shone bright like a diamond, gaining 183%.

In spite of the heavy fall in price, there still wouldn't be many who think Powell Industries' price-to-earnings (or "P/E") ratio of 20.7x is worth a mention when the median P/E in the United States is similar at about 19x. 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 have been advantageous for Powell Industries as its earnings have been rising faster than most other companies. One possibility is that the P/E is moderate because investors think this strong earnings performance might be about to tail off. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

Is There Some Growth For Powell Industries?

In order to justify its P/E ratio, Powell Industries would need to produce growth that's similar to the market.

If we review the last year of earnings growth, the company posted a terrific increase of 172%. The latest three year period has also seen an excellent 23,029% overall rise in EPS, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

Shifting to the future, estimates from the two analysts covering the company suggest earnings should grow by 9.7% over the next year. That's shaping up to be materially lower than the 15% growth forecast for the broader market.

In light of this, it's curious that Powell Industries' P/E sits in line with the majority of other companies. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

Following Powell Industries' share price tumble, its P/E is now hanging on to the median market P/E. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Powell Industries' analyst forecasts revealed that its inferior earnings outlook isn't impacting its P/E as much as we would have predicted. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
