While not a mind-blowing move, it is good to see that the Shenzhen Hepalink Pharmaceutical Group Co., Ltd. (SZSE:002399) share price has gained 14% in the last three months. But that can't change the reality that over the longer term (five years), the returns have been really quite dismal. Indeed, the share price is down 52% in the period. So we're not so sure if the recent bounce should be celebrated. However, in the best case scenario (far from fait accompli), this improved performance might be sustained.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over five years Shenzhen Hepalink Pharmaceutical Group's earnings per share dropped significantly, falling to a loss, with the share price also lower. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. But we would generally expect a lower price, given the situation.

A Different Perspective

While the broader market lost about 12% in the twelve months, Shenzhen Hepalink Pharmaceutical Group shareholders did even worse, losing 15%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 9% per year over five years. 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.
