Watts Water Technologies, Inc.'s (NYSE:WTS) price-to-earnings (or "P/E") ratio of 26.3x might make it look like a strong sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 16x and even P/E's below 9x are quite common. 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 Watts Water Technologies as its earnings have risen in spite of the market's earnings going into reverse. 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.

Is There Enough Growth For Watts Water Technologies?

In order to justify its P/E ratio, Watts Water Technologies would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered a decent 4.5% gain to the company's bottom line. Pleasingly, EPS has also lifted 133% in aggregate from three years ago, partly thanks to the last 12 months of growth. 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 8.7% each year as estimated by the eight analysts watching the company. With the market predicted to deliver 11% growth each year, the company is positioned for a comparable earnings result.

With this information, we find it interesting that Watts Water Technologies is trading at a high P/E compared to the market. Apparently many investors in the company are more bullish than analysts indicate and aren't willing to let go of their stock right now. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

What We Can Learn From Watts Water Technologies' P/E?

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that Watts Water Technologies 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.
