Are you under the impression that because JB puts his holdings in different accounts or other peoples accounts (ex wife) he can freely sell his shares without disclosing to the market as soon as he is aware of any news, good or bad?

I suppose it can work the other both ways also.
If these accounts still hold his shares you can probably guess that he suspects the share price will increase or at least there will be another pump.

A bit hard to keeping track of this as he stated they will only release the top 20 holdings on the website every 2 months.
Plenty of time for people with large holdings to exit or possibly enter before the retailer holders are aware.
