Well for every buyer there is a seller. 209MM at the offer is another matter. Shares would be at $60.
In my point of view, that time it was not well organized. If 209M shares were changed hands as simple buy and sell, it could be *100 more powerful if Calls options will be implemented. Anyway if it was a lot of buys, than somebody was selling a lot. Otherwise, stock will jump.
That's what I meant by "at the offer" as obv there was a lot of 2-way action. Simply lifting offers and we're talking a three digit figure on the shares.
It popped up in the 30 minutes before start of RTH session on Tuesday, Some fund prolly said I'm not going to miss this opportunity to get out of this turkey plus the meme'rs and bam sold bigtime from 930am on. Volume since nothing out of the ordinary:-
