Hefei Meyer Optoelectronic Technology Inc. (SZSE:002690) shareholders should be happy to see the share price up 15% in the last month. But that doesn't help the fact that the three year return is less impressive. After all, the share price is down 34% in the last three years, significantly under-performing the market.

The recent uptick of 4.1% could be a positive sign of things to come, so let's take a look at historical fundamentals.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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).

Although the share price is down over three years, Hefei Meyer Optoelectronic Technology actually managed to grow EPS by 16% per year in that time. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Or else the company was over-hyped in the past, and so its growth has disappointed.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

We note that, in three years, revenue has actually grown at a 13% annual rate, so that doesn't seem to be a reason to sell shares. It's probably worth investigating Hefei Meyer Optoelectronic Technology further; while we may be missing something on this analysis, there might also be an opportunity.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Hefei Meyer Optoelectronic Technology's TSR for the last 3 years was -29%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We regret to report that Hefei Meyer Optoelectronic Technology shareholders are down 29% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 17%. 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. On the bright side, long term shareholders have made money, with a gain of 2% per year over half a decade. 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.
