Concrete Pumping Holdings, Inc. (NASDAQ:BBCP) shareholders would be excited to see that the share price has had a great month, posting a 26% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 11% in the last twelve months.

Following the firm bounce in price, given around half the companies in the United States have price-to-earnings ratios (or "P/E's") below 19x, you may consider Concrete Pumping Holdings as a stock to potentially avoid with its 27.2x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

While the market has experienced earnings growth lately, Concrete Pumping Holdings' earnings have gone into reverse gear, which is not great. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

There's an inherent assumption that a company should outperform the market for P/E ratios like Concrete Pumping Holdings' to be considered reasonable.

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 50%. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Shifting to the future, estimates from the four analysts covering the company suggest earnings should grow by 53% over the next year. With the market only predicted to deliver 15%, the company is positioned for a stronger earnings result.

With this information, we can see why Concrete Pumping Holdings is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Key Takeaway

Concrete Pumping Holdings shares have received a push in the right direction, but its P/E is elevated too. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Concrete Pumping Holdings 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.
