Southern (NYSE:SO) shareholders notch a 15% CAGR over 5 years, yet earnings have been shrinking

If you buy and hold a stock for many years, you'd hope to be making a profit. Furthermore, you'd generally like to see the share price rise faster than the market. Unfortunately for shareholders, while the The Southern Company (NYSE:SO) share price is up 67% in the last five years, that's less than the market return. Some buyers are laughing, though, with an increase of 29% in the last year.

Since the stock has added US$4.5b to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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 five years of share price growth, Southern actually saw its EPS drop 2.4% per year.

By glancing at these numbers, we'd posit that the decline in earnings per share is not representative of how the business has changed over the years. 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.

In contrast revenue growth of 6.3% per year is probably viewed as evidence that Southern is growing, a real positive. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Southern's TSR for the last 5 years was 103%, 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

We're pleased to report that Southern shareholders have received a total shareholder return of 33% over one year. And that does include the dividend. That's better than the annualised return of 15% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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. Like risks, for instance. Every company has them, and we've spotted 3 warning signs for Southern (of which 1 doesn't sit too well with us!) you should know about.
