CenterPoint Energy, Inc.'s (NYSE:CNP) price-to-earnings (or "P/E") ratio of 22.6x 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 18x and even P/E's below 11x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

Recent times have been advantageous for CenterPoint Energy as its earnings have been rising faster than most other companies. The P/E is probably high because investors think this strong earnings performance will continue. If not, then existing shareholders might be a little nervous about the viability of the share price.

Keen to find out how analysts think CenterPoint Energy's future stacks up against the industry? In that case, our free report is a great place to start.

Does Growth Match The High P/E?

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

Retrospectively, the last year delivered an exceptional 19% gain to the company's bottom line. The strong recent performance means it was also able to grow EPS by 33% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Turning to the outlook, the next three years should generate growth of 9.9% each year as estimated by the twelve analysts watching the company. With the market predicted to deliver 11% growth per year, the company is positioned for a comparable earnings result.

With this information, we find it interesting that CenterPoint Energy 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.

The Final Word

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 CenterPoint Energy currently trades on a higher than expected P/E since its forecast growth is only in line with the wider market. 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.
