Generally speaking long term investing is the way to go. But unfortunately, some companies simply don't succeed. To wit, the Huachuang Yunxin Digital Technology Co., Ltd. (SHSE:600155) share price managed to fall 59% over five long years. That's an unpleasant experience for long term holders.

While the stock has risen 3.6% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the five years over which the share price declined, Huachuang Yunxin Digital Technology's earnings per share (EPS) dropped by 15% each year. This change in EPS is reasonably close to the 16% average annual decrease in the share price. This suggests that market participants have not changed their view of the company all that much. Rather, the share price has approximately tracked EPS growth.

The total return of 18% received by Huachuang Yunxin Digital Technology shareholders over the last year isn't far from the market return of -20%. So last year was actually even worse than the last five years, which cost shareholders 10% per year. It will probably take a substantial improvement in the fundamental performance for the company to reverse this trend. It's always interesting to track share price performance over the longer term.
