BGL - Share Price forecast and results, page-253

Also - Hypothetically of course:
If a cornerstone investor is getting frustrated with board and or management they may short sell the stock against their own long position to - hedge both ways or to deny board / staff SP related performance remuneration / options.
I'd see this as an effective way to spur on lazy / greedy board / management - think knife to throat style - no market notice required as still holds original position and lays out demands. Demands not met - keep shorting till satisfied or hit original holding size in shorts. Further breakdown of relations may see C/Stone reach their holding size in shorts. With an equally long and short position (basically uninvested) I think the CS would have tremendous bargaining power - a ceasing to be a substantial holder notice could be dropped at this point further destabilising the stock and the CS walks away having closed all positions.
As I'm a novice still I would like to be corrected if my understanding (particularly re: disclosure to market) of this is incorrect.
Thanks lanek
