Those holding Asymchem Laboratories (Tianjin) Co., Ltd. (SZSE:002821) shares would be relieved that the share price has rebounded 26% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 23% in the last twelve months.

Even after such a large jump in price, Asymchem Laboratories (Tianjin) may still be sending very bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 14.2x, since almost half of all companies in China have P/E ratios greater than 31x and even P/E's higher than 56x 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.

Recent times haven't been advantageous for Asymchem Laboratories (Tianjin) as its earnings have been falling quicker than most other companies. The P/E is probably low because investors think this poor earnings performance isn't going to improve at all. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. Or at the very least, you'd be hoping the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.

Does Growth Match The Low P/E?

There's an inherent assumption that a company should far underperform the market for P/E ratios like Asymchem Laboratories (Tianjin)'s to be considered reasonable.

Retrospectively, the last year delivered a frustrating 11% decrease to the company's bottom line. Even so, admirably EPS has lifted 255% in aggregate from three years ago, notwithstanding the last 12 months. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Turning to the outlook, the next year should bring diminished returns, with earnings decreasing 19% as estimated by the analysts watching the company. Meanwhile, the broader market is forecast to expand by 42%, which paints a poor picture.

In light of this, it's understandable that Asymchem Laboratories (Tianjin)'s P/E would sit below the majority of other companies. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Key Takeaway

Asymchem Laboratories (Tianjin)'s recent share price jump still sees its P/E sitting firmly flat on the ground. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

As we suspected, our examination of Asymchem Laboratories (Tianjin)'s analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
