Investors in AGL Energy (ASX:AGL) have seen stellar returns of 103% over the past three years

One simple way to benefit from the stock market is to buy an index fund. But many of us dare to dream of bigger returns, and build a portfolio ourselves. Just take a look at AGL Energy Limited (ASX:AGL), which is up 79%, over three years, soundly beating the market return of 5.8% (not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 25% in the last year, including dividends.

So let's assess the underlying fundamentals over the last 3 years and see if they've moved in lock-step with shareholder returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

AGL Energy became profitable within the last three years. That would generally be considered a positive, so we'd expect the share price to be up.

It is of course excellent to see how AGL Energy has grown profits over the years, but the future is more important for shareholders. It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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 AGL Energy, it has a TSR of 103% for the last 3 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 AGL Energy shareholders have received a total shareholder return of 25% over one year. That's including the dividend. That certainly beats the loss of about 5% per year over the last half decade. The long term loss makes us cautious, but the short term TSR gain certainly hints at a brighter future. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
