When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 19x, you may consider THOR Industries, Inc. (NYSE:THO) as a stock to potentially avoid with its 27x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

THOR Industries could be doing better as its earnings have been going backwards lately while most other companies have been seeing positive earnings growth. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

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

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 28%. As a result, earnings from three years ago have also fallen 72% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 30% per annum during the coming three years according to the analysts following the company. That's shaping up to be materially higher than the 11% per annum growth forecast for the broader market.

With this information, we can see why THOR Industries is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.
