While it may not be enough for some shareholders, we think it is good to see the The AES Corporation (NYSE:AES) share price up 24% in a single quarter. But that doesn't change the fact that the returns over the last three years have been less than pleasing. In fact, the share price is down 26% in the last three years, falling well short of the market return.

After losing 5.1% this past week, it's worth investigating the company's fundamentals to see what we can infer from past 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).

AES became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. So it's worth looking at other metrics to try to understand the share price move.

We note that, in three years, revenue has actually grown at a 8.0% annual rate, so that doesn't seem to be a reason to sell shares. This analysis is just perfunctory, but it might be worth researching AES more closely, as sometimes stocks fall unfairly. This could present an opportunity.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. So we recommend checking out this free report showing consensus forecasts

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for AES the TSR over the last 3 years was -19%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

AES shareholders are down 5.8% for the year (even including dividends), but the market itself is up 23%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 6%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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. Even so, be aware that AES is showing 4 warning signs in our investment analysis , and 1 of those is potentially serious...
