Investors in Shenzhen Dynanonic (SZSE:300769) from three years ago are still down 80%, even after 7.4% gain this past week

Every investor on earth makes bad calls sometimes. But you want to avoid the really big losses like the plague. So take a moment to sympathize with the long term shareholders of Shenzhen Dynanonic Co., Ltd (SZSE:300769), who have seen the share price tank a massive 80% over a three year period. That'd be enough to cause even the strongest minds some disquiet. The falls have accelerated recently, with the share price down 20% in the last three months. We really feel for shareholders in this scenario. It's a good reminder of the importance of diversification, and it's worth keeping in mind there's more to life than money, anyway.

On a more encouraging note the company has added CN¥660m to its market cap in just the last 7 days, so let's see if we can determine what's driven the three-year loss for shareholders.

Given that Shenzhen Dynanonic 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. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last three years, Shenzhen Dynanonic saw its revenue grow by 20% per year, compound. That's a pretty good rate of top-line growth. So it seems unlikely the 22% share price drop (each year) is entirely about the revenue. It could be that the losses were much larger than expected. If you buy into companies that lose money then you always risk losing money yourself. Just don't lose the lesson.

A Different Perspective

While the broader market gained around 22% in the last year, Shenzhen Dynanonic shareholders lost 7.5%. 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 1.3%, 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. 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.
