When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, you can make far more than 100% on a really good stock. One great example is SG Micro Corp (SZSE:300661) which saw its share price drive 259% higher over five years. It's also good to see the share price up 30% over the last quarter.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving 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).

Over half a decade, SG Micro managed to grow its earnings per share at 24% a year. This EPS growth is reasonably close to the 29% average annual increase in the share price. This indicates that investor sentiment towards the company has not changed a great deal. Indeed, it would appear the share price is reacting to the EPS.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, SG Micro's TSR for the last 5 years was 262%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Although it hurts that SG Micro returned a loss of 11% in the last twelve months, the broader market was actually worse, returning a loss of 17%. Of course, the long term returns are far more important and the good news is that over five years, the stock has returned 29% for each year. It could be that the business is just facing some short term problems, but shareholders should keep a close eye on the fundamentals. 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.
