One simple way to benefit from the stock market is to buy an index fund. But if you buy good businesses at attractive prices, your portfolio returns could exceed the average market return. For example, Konka Group Co., Ltd. (SZSE:000016) shareholders have seen the share price rise 46% over three years, well in excess of the market return (34%, not including dividends).

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

Konka Group was able to grow its EPS at 29% per year over three years, sending the share price higher. This EPS growth is higher than the 13% average annual increase in the share price. Therefore, it seems the market has moderated its expectations for growth, somewhat.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Konka Group, it has a TSR of 51% for the last 3 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We regret to report that Konka Group shareholders are down 28% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 8.3%. 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 2%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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. Even so, be aware that Konka Group is showing 4 warning signs in our investment analysis , and 3 of those are a bit unpleasant...
