Zhongjie (Jiangsu) Technology Co.,Ltd. (SZSE:301072) shareholders should be happy to see the share price up 15% in the last quarter. But that doesn't change the fact that the returns over the last year have been less than pleasing. In fact, the price has declined 24% in a year, falling short of the returns you could get by investing in an index fund.

Since Zhongjie (Jiangsu) TechnologyLtd has shed CN¥452m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Unhappily, Zhongjie (Jiangsu) TechnologyLtd had to report a 28% decline in EPS over the last year. This proportional reduction in earnings per share isn't far from the 24% decrease in the share price. Therefore one could posit that the market has not become more concerned about the company, despite the lower EPS. Rather, the share price is remains a similar multiple of the EPS, suggesting the outlook remains the same.

A Different Perspective

We doubt Zhongjie (Jiangsu) TechnologyLtd shareholders are happy with the loss of 24% over twelve months. That falls short of the market, which lost 6.1%. That's disappointing, but it's worth keeping in mind that the market-wide selling wouldn't have helped. It's great to see a nice little 15% rebound in the last three months. Let's just hope this isn't the widely-feared 'dead cat bounce' (which would indicate further declines to come). 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.
