Synaptics Incorporated's (NASDAQ:SYNA) price-to-earnings (or "P/E") ratio of 22.9x might make it look like a sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 18x 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 as high as it is.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Synaptics has been doing quite well of late. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For Synaptics?

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

Retrospectively, the last year delivered an exceptional 88% gain to the company's bottom line. The latest three year period has also seen an excellent 38% overall rise in EPS, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

Looking ahead now, EPS is anticipated to slump, contracting by 94% per year during the coming three years according to the nine analysts following the company. With the market predicted to deliver 10% growth per annum, that's a disappointing outcome.

With this information, we find it concerning that Synaptics is trading at a P/E higher than the market. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as these declining earnings are likely to weigh heavily on the share price eventually.

The Final Word

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.

We've established that Synaptics currently trades on a much higher than expected P/E for a company whose earnings are forecast to decline. When we see a poor outlook with earnings heading backwards, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
