It hasn't been the best quarter for Astron Corporation Limited (ASX:ATR) shareholders, since the share price has fallen 22% in that time. But that scarcely detracts from the really solid long term returns generated by the company over five years. It's fair to say most would be happy with 168% the gain in that time. To some, the recent pullback wouldn't be surprising after such a fast rise. Of course, that doesn't necessarily mean it's cheap now.

While the stock has fallen 14% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

Check out our latest analysis for Astron

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. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. 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.

In the last 5 years Astron saw its revenue grow at 9.5% per year. That's a pretty good long term growth rate. Broadly speaking, this solid progress may well be reflected by the healthy share price gain of 22% per year over five years. It's well worth monitoring the growth trend in revenue, because if growth accelerates, that might signal an opportunity. Accelerating growth can be a sign of an inflection point - and could indicate profits lie ahead. Worth watching 100%

A Different Perspective

Astron shareholders are down 15% for the year, but the market itself is up 12%. 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. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
