For many, the main point of investing is to generate higher returns than the overall market. But every investor is virtually certain to have both over-performing and under-performing stocks. At this point some shareholders may be questioning their investment in Kunshan Kersen Science & Technology Co.,Ltd. (SHSE:603626), since the last five years saw the share price fall 44%. And some of the more recent buyers are probably worried, too, with the stock falling 25% in the last year. The falls have accelerated recently, with the share price down 16% in the last three months. We note that the company has reported results fairly recently; and the market is hardly delighted. You can check out the latest numbers in our company report.

If the past week is anything to go by, investor sentiment for Kunshan Kersen Science & TechnologyLtd isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

Kunshan Kersen Science & TechnologyLtd wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Shareholders of unprofitable companies usually desire strong revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

Over five years, Kunshan Kersen Science & TechnologyLtd grew its revenue at 7.6% per year. That's a fairly respectable growth rate. We doubt many shareholders are ok with the fact the share price has fallen 8% each year for half a decade. Clearly, the expectations from back then have not been satisfied. The lesson is that if you buy shares in a money losing company you could end up losing money.

A Different Perspective

While the broader market lost about 15% in the twelve months, Kunshan Kersen Science & TechnologyLtd shareholders did even worse, losing 25% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 7% 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.
