this will be interesting. I would so like to be a fly on the wall wherever the buying is taking place. or selling for that matter. I think there is a 5% rule ownership, protects the DTA. However, it would not prevent sophisticated arrangements where someone else holds the shares and voting power but the consolidator gets any increase and "rents" the shares. I have seen Ackman do this.
Kinsa like selling covered calls. or buying them for that matter.
