Well, today it was up $0.05.
I think it's going to be hard to say how much of the change tomorrow is going to be due to the announcement. There is so much Disney that other news about other divisions could impact more. Disney also is easily affected by the entire market.
My opinion: I don't think it's going to have much impact on the stock price. It's going to be a huge outflow of money, yet the inflows after opening should help. I see the price +/- $0.10.
