CM Energy Tech Co., Ltd. (HKG:206) shareholders will doubtless be very grateful to see the share price up 33% in the last quarter. But that doesn't change the fact that the returns over the last three years have been less than pleasing. Truth be told the share price declined 27% in three years and that return, Dear Reader, falls short of what you could have got from passive investing with an index fund.

The recent uptick of 11% could be a positive sign of things to come, so let's take a look at historical fundamentals.

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 way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the three years that the share price fell, CM Energy Tech's earnings per share (EPS) dropped by 14% each year. In comparison the 10% compound annual share price decline isn't as bad as the EPS drop-off. So the market may not be too worried about the EPS figure, at the moment -- or it may have previously priced some of the drop in.

What About The Total Shareholder Return (TSR)?

We've already covered CM Energy Tech's share price action, but we should also mention its total shareholder return (TSR). Arguably the TSR is a more complete return calculation because it accounts for the value of dividends (as if they were reinvested), along with the hypothetical value of any discounted capital that have been offered to shareholders. CM Energy Tech's TSR of was a loss of 24% for the 3 years. That wasn't as bad as its share price return, because it has paid dividends.

A Different Perspective

CM Energy Tech shareholders are down 1.3% for the year, but the market itself is up 33%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 0.4%, 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.
