This week we saw the Sichuan Jinshi Technology Co.,Ltd (SZSE:002951) share price climb by 17%. But will that repair the damage for the weary investors who have owned this stock as it declined over half a decade? Probably not. In fact, the share price has tumbled down a mountain to land 81% lower after that period. The recent bounce might mean the long decline is over, but we are not confident. The million dollar question is whether the company can justify a long term recovery. We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

On a more encouraging note the company has added CN¥369m to its market cap in just the last 7 days, so let's see if we can determine what's driven the five-year loss for shareholders.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

Over five years Sichuan Jinshi TechnologyLtd'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. However, we can say we'd expect to see a falling share price in this scenario.

A Different Perspective

While the broader market lost about 11% in the twelve months, Sichuan Jinshi TechnologyLtd shareholders did even worse, losing 44%. 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 13% over the last half decade. 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
