With a price-to-earnings (or "P/E") ratio of 56.5x The Clorox Company (NYSE:CLX) 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 11x are not unusual. 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 advantageous for Clorox 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For Clorox?

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

If we review the last year of earnings growth, the company posted a terrific increase of 314%. However, this wasn't enough as the latest three year period has seen a very unpleasant 18% drop in EPS in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 38% per year as estimated by the analysts watching the company. That's shaping up to be materially higher than the 11% each year growth forecast for the broader market.

With this information, we can see why Clorox 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.

The Final Word

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.

As we suspected, our examination of Clorox's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. Right now shareholders are comfortable with the P/E as they are quite confident future earnings aren't under threat. It's hard to see the share price falling strongly in the near future under these circumstances.
