Looking at the top 20 shareholders 17 versus 18

It would appear that the 3 biggest shareholder Prof Xiaodong Chen left the building with 28,769,936 shares
Open Platform Systems gone approx 10,000,000
Citicorp Nominess gone approx 10,000,000
Thorney Corp gone approx 10,000,000

Thats nearly 59,000,000 shares

Then from July 18 until now approx 100 million shares have been traded on the way down.
Certainly some shuffling of the deck chairs. Is it a top twenty offloading or retail trading out.
Guess will find out in the next annual report.

Does seem unusual for the 3rd biggest holder to be opting out just as the company is getting underway, or maybe he changed the name of his shareholding.
