Buying shares in the best businesses can build meaningful wealth for you and your family. While the best companies are hard to find, but they can generate massive returns over long periods. Don't believe it? Then look at the Advance ZincTek Limited (ASX:ANO) share price. It's 693% higher than it was five years ago. If that doesn't get you thinking about long term investing, we don't know what will. It's also good to see the share price up 19% over the last quarter. We love happy stories like this one. The company should be really proud of that performance!

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

We don't think that Advance ZincTek's modest trailing twelve month profit has the market's full attention at the moment. We think revenue is probably a better guide. As a general rule, we think this kind of company is more comparable to loss-making stocks, since the actual profit is so low. For shareholders to have confidence a company will grow profits significantly, it must grow revenue.

In the last 5 years Advance ZincTek saw its revenue grow at 17% per year. Even measured against other revenue-focussed companies, that's a good result. Fortunately, the market has not missed this, and has pushed the share price up by 51% per year in that time. Despite the strong run, top performers like Advance ZincTek have been known to go on winning for decades. On the face of it, this looks lke a good opportunity, although we note sentiment seems very positive already.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

A Different Perspective

We regret to report that Advance ZincTek shareholders are down 35% for the year. Unfortunately, that's worse than the broader market decline of 2.7%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Longer term investors wouldn't be so upset, since they would have made 51%, 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.

Advance ZincTek is not the only stock that insiders are buying. For those who like to find winning investments this freelist of growing companies with recent insider purchasing, could be just the ticket.
