Over the last month the Aeris Resources Limited (ASX:AIS) has been much stronger than before, rebounding by 42%. But the last three years have seen a terrible decline. Indeed, the share price is down a whopping 83% in the last three years. So it's about time shareholders saw some gains. But the more important question is whether the underlying business can justify a higher price still. We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

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.

Given that Aeris Resources didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Shareholders of unprofitable companies usually desire strong revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

Over three years, Aeris Resources grew revenue at 14% per year. That's a pretty good rate of top-line growth. So it's hard to believe the share price decline of 22% per year is due to the revenue. More likely, the market was spooked by the cost of that revenue. This is exactly why investors need to diversify - even when a loss making company grows revenue, it can fail to deliver for shareholders.

A Different Perspective

Aeris Resources provided a TSR of 7.3% over the last twelve months. But that return falls short of the market. On the bright side, that's still a gain, and it's actually better than the average return of 2% over half a decade It is possible that returns will improve along with the business fundamentals. 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.
