TopBuild Corp.'s (NYSE:BLD) price-to-earnings (or "P/E") ratio of 22.4x 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 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 elevated P/E.

Recent times have been pleasing for TopBuild as its earnings have risen in spite of the market's earnings going into reverse. 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.

Is There Enough Growth For TopBuild?

The only time you'd be truly comfortable seeing a P/E as high as TopBuild's is when the company's growth is on track to outshine the market.

Retrospectively, the last year delivered a decent 13% gain to the company's bottom line. The latest three year period has also seen an excellent 157% overall rise in EPS, aided somewhat by its short-term performance. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 6.2% over the next year. That's shaping up to be materially lower than the 11% growth forecast for the broader market.

In light of this, it's alarming that TopBuild's P/E sits above the majority of other companies. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.

The Key Takeaway

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.

Our examination of TopBuild's analyst forecasts revealed that its inferior earnings outlook isn't impacting its high P/E anywhere near as much as we would have predicted. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with TopBuild, and understanding should be part of your investment process.
