The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of Axos Financial, Inc. (NYSE:AX) stock is up an impressive 164% over the last five years. Also pleasing for shareholders was the 27% gain in the last three months. The company reported its financial results recently; you can catch up on the latest numbers by reading our company report.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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. 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, Axos Financial achieved compound earnings per share (EPS) growth of 26% per year. This EPS growth is higher than the 21% average annual increase in the share price. So one could conclude that the broader market has become more cautious towards the stock. The reasonably low P/E ratio of 9.24 also suggests market apprehension.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. This free interactive report on Axos Financial's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

A Different Perspective

It's nice to see that Axos Financial shareholders have received a total shareholder return of 61% over the last year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 21% per year), it would seem that the stock's performance has improved in recent times. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for Axos Financial you should know about.
