Investors in Voltronic Power Technology (TWSE:6409) have seen solid returns of 221% over the past five years

When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the Voltronic Power Technology Corp. (TWSE:6409) share price has soared 188% in the last half decade. Most would be very happy with that. Also pleasing for shareholders was the 12% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 16% in 90 days).

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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, Voltronic Power Technology managed to grow its earnings per share at 14% a year. This EPS growth is lower than the 24% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. As it happens, Voltronic Power Technology's TSR for the last 5 years was 221%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 29% in the last year, Voltronic Power Technology shareholders lost 7.3% (even including dividends). 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 26%, 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. It's always interesting to track share price performance over the longer term. But to understand Voltronic Power Technology better, we need to consider many other factors.
