Investors in Southern Copper (NYSE:SCCO) have seen stellar returns of 192% over the past five years

The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the Southern Copper Corporation (NYSE:SCCO) share price has soared 129% in the last half decade. Most would be very happy with that. It's also good to see the share price up 16% over the last quarter. But this move may well have been assisted by the reasonably buoyant market (up 12% in 90 days).

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 Copper achieved compound earnings per share (EPS) growth of 9.5% per year. This EPS growth is slower than the share price growth of 18% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Southern Copper, it has a TSR of 192% for the last 5 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

Southern Copper provided a TSR of 21% over the last twelve months. Unfortunately this falls short of the market return. On the bright side, the longer term returns (running at about 24% a year, over half a decade) look better. Maybe the share price is just taking a breather while the business executes on its growth strategy. 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 Southern Copper is showing 2 warning signs in our investment analysis , and 1 of those can't be ignored...
