If you want to compound wealth in the stock market, you can do so by buying an index fund. But the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, the Mueller Water Products, Inc. (NYSE:MWA) share price is up 84% in the last five years, slightly above the market return. Zooming in, the stock is up a respectable 19% in the last year.

In light of the stock dropping 3.4% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive five-year return.

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, Mueller Water Products achieved compound earnings per share (EPS) growth of 27% per year. The EPS growth is more impressive than the yearly share price gain of 13% over the same period. Therefore, it seems the market has become relatively pessimistic about the company.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Dive deeper into the earnings by checking this interactive graph of Mueller Water Products' earnings, revenue and cash flow.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Mueller Water Products, it has a TSR of 102% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Mueller Water Products provided a TSR of 21% over the last twelve months. But that return falls short of the market. The silver lining is that the gain was actually better than the average annual return of 15% per year over five year. This could indicate that the company is winning over new investors, as it pursues its strategy. Investors who like to make money usually check up on insider purchases, such as the price paid, and total amount bought.
