HD,

The building of cross trades could mean that someone may be trying to build up the numbers of voters needed to vote in favour of the SOA resolution. It has happened before. And usually, the time allowed for the meeting on voting for the SOA can be set up for one purpose. And that is that the buying party can gauge the feelings of the shareholers and market at large, and work out and prepare it's tactics on how to attack and defeat that attitude.

The huge sale could also have been that someone knew what was going to happen overnight with the DOW in USA.
But, DYOR.
