The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But if you buy shares in a really great company, you can more than double your money. To wit, the IGO Limited (ASX:IGO) share price has flown 141% in the last three years. Most would be happy with that. Also pleasing for shareholders was the 21% gain in the last three months.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace…' One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

IGO became profitable within the last three years. Given the importance of this milestone, it's not overly surprising that the share price has increased strongly.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

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. Dive deeper into the earnings by checking this interactive graph of IGO's earnings, revenue and cash flow.

What about the Total Shareholder Return (TSR)?

We'd be remiss not to mention the difference between IGO's total shareholder return (TSR) and its share price return. Arguably the TSR is a more complete return calculation because it accounts for the value of dividends (as if they were reinvested), along with the hypothetical value of any discounted capital that have been offered to shareholders. IGO's TSR of 159% for the 3 years exceeded its share price return, because it has paid dividends.

A Different Perspective

We're pleased to report that IGO shareholders have received a total shareholder return of 124% over one year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 20% 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 for instance, the ever-present spectre of investment risk. We've identified 4 warning signs with IGO , and understanding them should be part of your investment process.
