Xiangtan Electric Manufacturing Co. Ltd. (SHSE:600416) shareholders might be concerned after seeing the share price drop 18% in the last quarter. But in stark contrast, the returns over the last half decade have impressed. In fact, the share price is 160% higher today. So while it's never fun to see a share price fall, it's important to look at a longer time horizon. Ultimately business performance will determine whether the stock price continues the positive long term trend. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 34% drop, in the last year.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies.

A Different Perspective

While the broader market lost about 0.2% in the twelve months, Xiangtan Electric Manufacturing shareholders did even worse, losing 34%. 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. On the bright side, long term shareholders have made money, with a gain of 21% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
