maing, it's pretty tough to buy on the rumor about now! The next buys/sells will be on the news itself.
My guess, the "leak" (totally an assumption on my part that a leak is part of this story) was strongly suspected on Friday, and possibly confirmed that day; management decided to see what would happen Monday morning, they saw, they halted.
It would be fantastic if the halt had something to do with FB or Fruit's pending releases, but I'm still thinking it's a deal that isn't quite done, a few t's to cross and i's to dot.
Hal, nice bit on irony!
