Listen to the news

Productive Technologies Company Limited (HKG:650) shareholders (or potential shareholders) will be happy to see that the Executive Chairman & CEO, Erzhuang Liu, recently bought a whopping HK$4.4m worth of stock, at a price of HK$0.20. That purchase boosted their holding by 58%, which makes us wonder if the move was inspired by quietly confident deeply-felt optimism.

Productive Technologies Insider Transactions Over The Last Year

In fact, the recent purchase by Erzhuang Liu was the biggest purchase of Productive Technologies shares made by an insider individual in the last twelve months, according to our records. That means that an insider was happy to buy shares at around the current price of HK$0.21. Of course they may have changed their mind. But this suggests they are optimistic. While we always like to see insider buying, it's less meaningful if the purchases were made at much lower prices, as the opportunity they saw may have passed. Happily, the Productive Technologies insider decided to buy shares at close to current prices. The only individual insider to buy over the last year was Erzhuang Liu.

Insider Ownership

Many investors like to check how much of a company is owned by insiders. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Our data indicates that Productive Technologies insiders own about HK$49m worth of shares (which is 3.1% of the company). We do note, however, it is possible insiders have an indirect interest through a private company or other corporate structure. Overall, this level of ownership isn't that impressive, but it's certainly better than nothing!

What Might The Insider Transactions At Productive Technologies Tell Us?

It is good to see the recent insider purchase. And an analysis of the transactions over the last year also gives us confidence. But we don't feel the same about the fact the company is making losses. Insiders likely see value in Productive Technologies shares, given these transactions (along with notable insider ownership of the company). I like to dive deeper into how a company has performed in the past. You can find historic revenue and earnings in this detailed graph.

Of course Productive Technologies may not be the best stock to buy. So you may wish to see this free collection of high quality companies.
