Dycom Industries, Inc.'s (NYSE:DY) price-to-earnings (or "P/E") ratio of 22.5x might make it look like a sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 17x and even P/E's below 10x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Dycom Industries has been doing quite well of late. 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.

How Is Dycom Industries' Growth Trending?

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

Retrospectively, the last year delivered an exceptional 34% gain to the company's bottom line. Pleasingly, EPS has also lifted 267% in aggregate from three years ago, thanks to the last 12 months of growth. 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 eight analysts covering the company suggest earnings should grow by 11% per year over the next three years. With the market predicted to deliver 10% growth each year, the company is positioned for a comparable earnings result.

With this information, we find it interesting that Dycom Industries is trading at a high P/E compared to the market. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.

What We Can Learn From Dycom Industries' P/E?

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

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