The five-year returns have been solid for Astron (ASX:ATR) shareholders despite underlying losses increasing

The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Astron Corporation Limited (ASX:ATR) share price has soared 175% in the last half decade. Most would be very happy with that. In more good news, the share price has risen 28% in thirty days.

Since the stock has added AU$15m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

Given that Astron 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. When a company doesn't make profits, we'd generally expect to see good revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

In the last 5 years Astron saw its revenue grow at 28% per year. That's well above most pre-profit companies. So it's not entirely surprising that the share price reflected this performance by increasing at a rate of 22% per year, in that time. This suggests the market has well and truly recognized the progress the business has made. To our minds that makes Astron worth investigating - it may have its best days ahead.

A Different Perspective

Astron shareholders are down 30% for the year, but the market itself is up 6.1%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 22%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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 3 warning signs with Astron (at least 1 which shouldn't be ignored) , and understanding them should be part of your investment process.
