When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. For example, the American Express Company (NYSE:AXP) share price has soared 151% in the last half decade. Most would be very happy with that. It's also good to see the share price up 19% over the last quarter. But this move may well have been assisted by the reasonably buoyant market (up 7.8% in 90 days).

The past week has proven to be lucrative for American Express investors, so let's see if fundamentals drove the company's five-year performance.

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, American Express managed to grow its earnings per share at 11% a year. This EPS growth is lower than the 20% 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.

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. In the case of American Express, it has a TSR of 169% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that American Express shareholders have received a total shareholder return of 85% over one year. That's including the dividend. That's better than the annualised return of 22% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time.
