Suzhou Maxwell Technologies Co., Ltd. (SZSE:300751) shareholders might understandably be very concerned that the share price has dropped 45% in the last quarter. But that does not change the realty that the stock's performance has been terrific, over five years. In fact, during that period, the share price climbed 566%. Impressive! So we don't think the recent decline in the share price means its story is a sad one. Of course what matters most is whether the business can improve itself sustainably, thus justifying a higher price. Unfortunately not all shareholders will have held it for the long term, so spare a thought for those caught in the 63% decline over the last twelve months. We love happy stories like this one. The company should be really proud of that performance!

Although Suzhou Maxwell Technologies has shed CN¥1.7b from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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 imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over half a decade, Suzhou Maxwell Technologies managed to grow its earnings per share at 28% a year. This EPS growth is lower than the 46% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

We know that Suzhou Maxwell Technologies has improved its bottom line over the last three years, but what does the future have in store? It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Suzhou Maxwell Technologies' TSR for the last 5 years was 579%, 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 Suzhou Maxwell Technologies shareholders are down 63% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 4.6%. 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. Longer term investors wouldn't be so upset, since they would have made 47%, each year, over five years. 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.
