Teleflex Incorporated's (NYSE:TFX) price-to-earnings (or "P/E") ratio of 43.6x 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.

With earnings that are retreating more than the market's of late, Teleflex has been very sluggish. It might be that many expect the dismal 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?

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

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 28%. As a result, earnings from three years ago have also fallen 25% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 32% per annum over the next three years. Meanwhile, the rest of the market is forecast to only expand by 10% per year, which is noticeably less attractive.

With this information, we can see why Teleflex is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

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.

As we suspected, our examination of Teleflex's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
