Carpenter Technology Corporation's (NYSE:CRS) price-to-earnings (or "P/E") ratio of 37.9x 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 17x and even P/E's below 10x are quite common. 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.

Recent times have been advantageous for Carpenter Technology as its earnings have been rising faster than most other companies. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For Carpenter Technology?

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

Retrospectively, the last year delivered an exceptional 84% gain to the company's bottom line. Still, EPS has barely risen at all from three years ago in total, which is not ideal. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Turning to the outlook, the next three years should generate growth of 31% per year as estimated by the seven analysts watching the company. Meanwhile, the rest of the market is forecast to only expand by 11% each year, which is noticeably less attractive.

With this information, we can see why Carpenter Technology 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 Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Carpenter Technology'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. Unless these conditions change, they will continue to provide strong support to the share price.
