With a price-to-earnings (or "P/E") ratio of 28.6x Smith & Nephew plc (LON:SN.) may be sending very bearish signals at the moment, given that almost half of all companies in the United Kingdom have P/E ratios under 16x and even P/E's lower than 10x 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 Smith & Nephew 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. If not, then existing shareholders might be a little nervous about the viability of the share price.

The only time you'd be truly comfortable seeing a P/E as steep as Smith & Nephew's is when the company's growth is on track to outshine the market decidedly.
If we review the last year of earnings growth, the company posted a terrific increase of 61%. Although, its longer-term performance hasn't been as strong with three-year EPS growth being relatively non-existent overall. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.
Turning to the outlook, the next three years should generate growth of 25% each year as estimated by the analysts watching the company. That's shaping up to be materially higher than the 15% per annum growth forecast for the broader market.
In light of this, it's understandable that Smith & Nephew's P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.
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 Smith & Nephew'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. Unless these conditions change, they will continue to provide strong support to the share price.
