It's understandable if you feel frustrated when a stock you own sees a lower share price. But sometimes broader market conditions have more of an impact on prices than the actual business performance. The Jiangyin Zhongnan Heavy Industries Co.,Ltd (SZSE:002445) share price is down 23% in the last year. But that actually beats the market decline of 26%. Longer term investors have fared much better, since the share price is up 5.4% in three years. The falls have accelerated recently, with the share price down 15% in the last three months. However, one could argue that the price has been influenced by the general market, which is down 19% in the same timeframe.

If the past week is anything to go by, investor sentiment for Jiangyin Zhongnan Heavy IndustriesLtd isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 Jiangyin Zhongnan Heavy IndustriesLtd grew its earnings per share, moving from a loss to a profit.

When a company has just transitioned to profitability, earnings per share growth is not always the best way to look at the share price action. So it makes sense to check out some other factors.

Jiangyin Zhongnan Heavy IndustriesLtd managed to grow revenue over the last year, which is usually a real positive. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

A Different Perspective

Although it hurts that Jiangyin Zhongnan Heavy IndustriesLtd returned a loss of 23% in the last twelve months, the broader market was actually worse, returning a loss of 26%. Of course, the long term returns are far more important and the good news is that over five years, the stock has returned 4% for each year. It could be that the business is just facing some short term problems, but shareholders should keep a close eye on the fundamentals. 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.
