When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, you can make far more than 100% on a really good stock. Long term O'Reilly Automotive, Inc. (NASDAQ:ORLY) shareholders would be well aware of this, since the stock is up 157% in five years.

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

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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.

Over half a decade, O'Reilly Automotive managed to grow its earnings per share at 19% a year. So the EPS growth rate is rather close to the annualized share price gain of 21% per year. That suggests that the market sentiment around the company hasn't changed much over that time. In fact, the share price seems to largely reflect the EPS growth.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

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.

A Different Perspective

O'Reilly Automotive shareholders are up 6.1% for the year. But that return falls short of the market. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 21% over five years. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider for instance, the ever-present spectre of investment risk.
