With a price-to-earnings (or "P/E") ratio of 5.9x Weifu High-Technology Group Co., Ltd. (SZSE:200581) may be sending very bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 32x and even P/E's higher than 59x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at Weifu High-Technology Group over the last year, which is not ideal at all. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Does Growth Match The Low P/E?

In order to justify its P/E ratio, Weifu High-Technology Group would need to produce anemic growth that's substantially trailing the market.

Retrospectively, the last year delivered a frustrating 31% decrease to the company's bottom line. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.

In light of this, it's understandable that Weifu High-Technology Group's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

The Key Takeaway

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

As we suspected, our examination of Weifu High-Technology Group revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.

Plus, you should also learn about these 2 warning signs we've spotted with Weifu High-Technology Group (including 1 which makes us a bit uncomfortable).
