The Fujian SBS Zipper Science&Technology Co., Ltd (SZSE:002098) share price has done very well over the last month, posting an excellent gain of 34%. Taking a wider view, although not as strong as the last month, the full year gain of 25% is also fairly reasonable.

In spite of the firm bounce in price, there still wouldn't be many who think Fujian SBS Zipper Science&Technology's price-to-earnings (or "P/E") ratio of 37.1x is worth a mention when the median P/E in China is similar at about 34x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

For instance, Fujian SBS Zipper Science&Technology's receding earnings in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

Does Growth Match The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like Fujian SBS Zipper Science&Technology's to be considered reasonable.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 70%. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 42% shows it's noticeably less attractive on an annualised basis.

With this information, we find it interesting that Fujian SBS Zipper Science&Technology is trading at a fairly similar P/E to the market. Apparently many investors in the company are less bearish than recent times would indicate and aren't willing to let go of their stock right now. They may be setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Key Takeaway

Fujian SBS Zipper Science&Technology's stock has a lot of momentum behind it lately, which has brought its P/E level with the market. 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.

Our examination of Fujian SBS Zipper Science&Technology revealed its three-year earnings trends aren't impacting its P/E as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Fujian SBS Zipper Science&Technology, and understanding should be part of your investment process.
