It's not possible to invest over long periods without making some bad investments. But you want to avoid the really big losses like the plague. So take a moment to sympathize with the long term shareholders of Juewei Food Co., Ltd. (SHSE:603517), who have seen the share price tank a massive 75% over a three year period. That might cause some serious doubts about the merits of the initial decision to buy the stock, to put it mildly. And more recent buyers are having a tough time too, with a drop of 57% in the last year. The falls have accelerated recently, with the share price down 32% in the last three months.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

During the three years that the share price fell, Juewei Food's earnings per share (EPS) dropped by 19% each year. The share price decline of 37% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

A Different Perspective

We regret to report that Juewei Food shareholders are down 57% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 21%. 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 4% per year over five years. 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.
