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%. For instance, the price of AutoZone, Inc. (NYSE:AZO) stock is up an impressive 205% over the last five years. The last week saw the share price soften some 1.2%.

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

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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, AutoZone managed to grow its earnings per share at 23% a year. This EPS growth is reasonably close to the 25% average annual increase in the share price. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Rather, the share price has approximately tracked EPS growth.

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. Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here..

A Different Perspective

AutoZone shareholders are up 4.3% for the year. Unfortunately this falls short of the market return. If we look back over five years, the returns are even better, coming in at 25% per year for five years. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. 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. Even so, be aware that AutoZone is showing 3 warning signs in our investment analysis , and 2 of those make us uncomfortable...
