After hours moves can be dramatic, we'll see where it's at tomorrow w/ full volume. It's good news for sure but you can't tell me Wall Street actually thought they would be broken up or anything drastic.
> but you can't tell me Wall Street actually thought
It's not binary. "Wall Street" is a lot of people independently pricing what they think is the probability and impact.
But so yes, Wall Street was absolutely pricing in a drastic breakup to some degree. If they'd thought it was even more likely, the bump would have been even larger.
