Tianjin Chase Sun Pharmaceutical Co.,Ltd's (SZSE:300026) price-to-earnings (or "P/E") ratio of 19.4x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 35x and even P/E's above 64x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Earnings have risen firmly for Tianjin Chase Sun PharmaceuticalLtd recently, which is pleasing to see. One possibility is that the P/E is low because investors think this respectable earnings growth might actually underperform 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.

What Are Growth Metrics Telling Us About The Low P/E?

There's an inherent assumption that a company should underperform the market for P/E ratios like Tianjin Chase Sun PharmaceuticalLtd's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 23% gain to the company's bottom line. As a result, it also grew EPS by 29% in total over the last three years. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 44% shows it's noticeably less attractive on an annualised basis.

In light of this, it's understandable that Tianjin Chase Sun PharmaceuticalLtd'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

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 Tianjin Chase Sun PharmaceuticalLtd maintains its low P/E on the weakness of its recent three-year growth being lower than the wider market forecast, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
