It hasn't been the best quarter for Shenzhen Sinexcel Electric Co.,Ltd. (SZSE:300693) shareholders, since the share price has fallen 30% in that time. But that doesn't change the fact that shareholders have received really good returns over the last five years. It's fair to say most would be happy with 238% the gain in that time. Generally speaking the long term returns will give you a better idea of business quality than short periods can. Only time will tell if there is still too much optimism currently reflected in the share price. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 41% drop, in the last year.

Since the long term performance has been good but there's been a recent pullback of 6.8%, let's check if the fundamentals match the share price.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over half a decade, Shenzhen Sinexcel ElectricLtd managed to grow its earnings per share at 71% a year. This EPS growth is higher than the 28% average annual increase in the share price. So one could conclude that the broader market has become more cautious towards the stock.

We know that Shenzhen Sinexcel ElectricLtd has improved its bottom line over the last three years, but what does the future have in store? You can see how its balance sheet has strengthened (or weakened) over time in this free interactive graphic.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Shenzhen Sinexcel ElectricLtd's TSR for the last 5 years was 249%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that Shenzhen Sinexcel ElectricLtd shareholders are down 40% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 16%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 28% per year over half a decade. 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.
