Anhui Zhongding Sealing Parts Co., Ltd. (SZSE:000887) shareholders should be happy to see the share price up 12% in the last month. But that wasn't enough to see the company deliver market-beating returns over the year. Specifically, the stock returned 23% whereas the market is down , having returned (-23%) over the last year.

While the last year has been tough for Anhui Zhongding Sealing Parts shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the unfortunate twelve months during which the Anhui Zhongding Sealing Parts share price fell, it actually saw its earnings per share (EPS) improve by 20%. Of course, the situation might betray previous over-optimism about growth.

It's surprising to see the share price fall so much, despite the improved EPS. But we might find some different metrics explain the share price movements better.

Given the yield is quite low, at 1.8%, we doubt the dividend can shed much light on the share price. Anhui Zhongding Sealing Parts managed to grow revenue over the last year, which is usually a real positive. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

A Different Perspective

We regret to report that Anhui Zhongding Sealing Parts shareholders are down 23% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 19%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 1.3% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
