The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of Broadex Technologies Co., Ltd. (SZSE:300548) stock is up an impressive 108% over the last five years. It's also up 8.6% in about a month.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

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. 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, Broadex Technologies achieved compound earnings per share (EPS) growth of 18% per year. So the EPS growth rate is rather close to the annualized share price gain of 16% per year. That suggests that the market sentiment around the company hasn't changed much over that time. Rather, the share price has approximately tracked EPS growth.

It is of course excellent to see how Broadex Technologies has grown profits over the years, but the future is more important for shareholders. If you are thinking of buying or selling Broadex Technologies stock, you should check out this FREE detailed report on its balance sheet.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. In the case of Broadex Technologies, it has a TSR of 113% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Broadex Technologies shareholders have received a total shareholder return of 35% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 16% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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 for instance, the ever-present spectre of investment risk.
