Unpleasant Surprises Could Be In Store For American Water Works Company, Inc.'s (NYSE:AWK) Shares

With a price-to-earnings (or "P/E") ratio of 28.5x American Water Works Company, Inc. (NYSE:AWK) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 18x and even P/E's lower than 10x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

American Water Works Company certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors’ willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

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

There's an inherent assumption that a company should far outperform the market for P/E ratios like American Water Works Company's to be considered reasonable.

Taking a look back first, we see that there was hardly any earnings per share growth to speak of for the company over the past year. Fortunately, a few good years before that means that it was still able to grow EPS by 19% in total over the last three years. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 8.7% per annum as estimated by the eleven analysts watching the company. Meanwhile, the rest of the market is forecast to expand by 11% per year, which is not materially different.

With this information, we find it interesting that American Water Works Company 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 Key Takeaway

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of American Water Works Company's 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.
