We think intelligent long term investing is the way to go. But along the way some stocks are going to perform badly. To wit, the Huachangda Intelligent Equipment Group Co.,Ltd. (SZSE:300278) share price managed to fall 61% over five long years. That's an unpleasant experience for long term holders. And some of the more recent buyers are probably worried, too, with the stock falling 28% in the last year. Unfortunately the share price momentum is still quite negative, with prices down 15% in thirty days.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Huachangda Intelligent Equipment GroupLtd became profitable within the last five years. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

In contrast to the share price, revenue has actually increased by 10% a year in the five year period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

A Different Perspective

We regret to report that Huachangda Intelligent Equipment GroupLtd shareholders are down 28% for the year. Unfortunately, that's worse than the broader market decline of 17%. 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 10% 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. 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. Consider risks, for instance. Every company has them, and we've spotted 2 warning signs for Huachangda Intelligent Equipment GroupLtd you should know about.
