Astec Industries, Inc. (NASDAQ:ASTE) shares have had a horrible month, losing 26% after a relatively good period beforehand. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 23% share price drop.

Although its price has dipped substantially, given close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 17x, you may still consider Astec Industries as a stock to avoid entirely with its 29.7x P/E ratio. 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 have been pleasing for Astec Industries as its earnings have risen in spite of the market's earnings going into reverse. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

Astec Industries' 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.

If we review the last year of earnings growth, the company posted a terrific increase of 214%. Still, incredibly EPS has fallen 29% in total from three years ago, which is quite disappointing. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 29% during the coming year according to the three analysts following the company. That's shaping up to be materially higher than the 12% growth forecast for the broader market.

With this information, we can see why Astec Industries is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Key Takeaway

Astec Industries' shares may have retreated, but its P/E is still flying high. 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.

We've established that Astec Industries maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
