The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For example, the TopBuild Corp. (NYSE:BLD) share price has soared 202% in the last half decade. Most would be very happy with that. In more good news, the share price has risen 14% in thirty days.

The past week has proven to be lucrative for TopBuild investors, so let's see if fundamentals drove the company's five-year performance.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During five years of share price growth, TopBuild achieved compound earnings per share (EPS) growth of 31% per year. The EPS growth is more impressive than the yearly share price gain of 25% over the same period. So one could conclude that the broader market has become more cautious towards the stock.

A Different Perspective

While the broader market gained around 27% in the last year, TopBuild shareholders lost 2.0%. 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. Longer term investors wouldn't be so upset, since they would have made 25%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
