The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. Long term O'Reilly Automotive, Inc.

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, O'Reilly Automotive achieved compound earnings per share (EPS) growth of 19% per year. So the EPS growth rate is rather close to the annualized share price gain of 23% per year. This indicates that investor sentiment towards the company has not changed a great deal. Rather, the share price has approximately tracked EPS growth.

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.
