It's nice to see the Kangda New Materials (Group) Co., Ltd. (SZSE:002669) share price up 15% in a week. But that doesn't change the fact that the returns over the last year have been less than pleasing. The cold reality is that the stock has dropped 34% in one year, under-performing the market.

While the stock has risen 15% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

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 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.

During the last year Kangda New Materials (Group) grew its earnings per share, moving from a loss to a profit.

Earnings per share growth rates aren't particularly useful for comparing with the share price, when a company has moved from loss to profit. But we may find different metrics more enlightening.

Kangda New Materials (Group)'s revenue is actually up 14% over the last year. Since we can't easily explain the share price movement based on these metrics, it might be worth considering how market sentiment has changed towards the stock.

A Different Perspective

We regret to report that Kangda New Materials (Group) shareholders are down 34% for the year. 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 5% 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.
