Jafron Biomedical Co.,Ltd. (SZSE:300529) shareholders should be happy to see the share price up 14% in the last month. But that is small recompense for the exasperating returns over three years. In that time, the share price dropped 68%. So the improvement may be a real relief to some. After all, could be that the fall was overdone.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Jafron BiomedicalLtd saw its EPS decline at a compound rate of 17% per year, over the last three years. This reduction in EPS is slower than the 31% annual reduction in the share price. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

A Different Perspective

While the broader market lost about 12% in the twelve months, Jafron BiomedicalLtd shareholders did even worse, losing 22% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 3% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
