Buying shares in the best businesses can build meaningful wealth for you and your family. And we've seen some truly amazing gains over the years. Don't believe it? Then look at the Mueller Industries, Inc. (NYSE:MLI) share price. It's 406% higher than it was five years ago. If that doesn't get you thinking about long term investing, we don't know what will. It's also good to see the share price up 27% over the last quarter.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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 imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During five years of share price growth, Mueller Industries achieved compound earnings per share (EPS) growth of 43% per year. This EPS growth is reasonably close to the 38% average annual increase in the share price. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. In fact, the share price seems to largely reflect the EPS growth.

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. In the case of Mueller Industries, it has a TSR of 444% 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

It's nice to see that Mueller Industries shareholders have received a total shareholder return of 99% over the last year. And that does include the dividend. That's better than the annualised return of 40% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
