A Look At AGL Energy's (ASX:AGL) Share Price Returns

Many investors define successful investing as beating the market average over the long term. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term AGL Energy Limited (ASX:AGL) shareholders have had that experience, with the share price dropping 48% in three years, versus a market return of about 23%. And the ride hasn't got any smoother in recent times over the last year, with the price 34% lower in that time. There was little comfort for shareholders in the last week as the price declined a further 1.5%.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the unfortunate three years of share price decline, AGL Energy actually saw its earnings per share (EPS) improve by 25% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

It's quite likely that the declining dividend has caused some investors to sell their shares, pushing the price lower in the process. It doesn't seem like the changes in revenue would have impacted the share price much, but a closer inspection of the data might reveal something.

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?

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. We note that for AGL Energy the TSR over the last 3 years was -38%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 4.3% in the last year, AGL Energy shareholders lost 30% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 0.5% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand AGL Energy better, we need to consider many other factors.
