If you love investing in stocks you're bound to buy some losers. But the long term shareholders of Kingfa Sci. & Tech. Co., Ltd. (SHSE:600143) have had an unfortunate run in the last three years. So they might be feeling emotional about the 69% share price collapse, in that time. And the ride hasn't got any smoother in recent times over the last year, with the price 27% lower in that time. Furthermore, it's down 14% in about a quarter. That's not much fun for holders.

With the stock having lost 5.7% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the three years that the share price fell, Kingfa Sci. & Tech's earnings per share (EPS) dropped by 33% each year. The 32% average annual share price decline is remarkably close to the EPS decline. So it seems like sentiment towards the stock hasn't changed all that much over time. It seems like the share price is reflecting the declining earnings per share.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Kingfa Sci. & Tech the TSR over the last 3 years was -67%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 13% in the twelve months, Kingfa Sci. & Tech shareholders did even worse, losing 25% (even including dividends). 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. Longer term investors wouldn't be so upset, since they would have made 6%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
