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 AECOM (NYSE:ACM) stock is up an impressive 174% over the last five years. On top of that, the share price is up 15% in about a quarter. But this move may well have been assisted by the reasonably buoyant market (up 8.2% in 90 days).

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

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, AECOM managed to grow its earnings per share at 23% a year. That makes the EPS growth particularly close to the yearly share price growth of 22%. 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.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, AECOM's TSR for the last 5 years was 181%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

AECOM shareholders have received returns of 33% over twelve months (even including dividends), which isn't far from the general market return. Most would be happy with a gain, and it helps that the year's return is actually better than the average return over five years, which was 23%. It is possible that management foresight will bring growth well into the future, even if the share price slows down. If you would like to research AECOM in more detail then you might want to take a look at whether insiders have been buying or selling shares in the company.
