Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And the truth is, you can make significant gains if you buy good quality businesses at the right price. To wit, the Shenzhen Aisidi share price has climbed 61% in five years, easily topping the market return of 11% (ignoring dividends).

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder 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 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).

During five years of share price growth, Shenzhen Aisidi achieved compound earnings per share (EPS) growth of 16% per year. The EPS growth is more impressive than the yearly share price gain of 10% over the same period. So it seems the market isn't so enthusiastic about the stock these days.

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. We note that for Shenzhen Aisidi the TSR over the last 5 years was 103%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Although it hurts that Shenzhen Aisidi returned a loss of 2.9% in the last twelve months, the broader market was actually worse, returning a loss of 24%. Of course, the long term returns are far more important and the good news is that over five years, the stock has returned 15% 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. 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. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for Shenzhen Aisidi you should know about.
