Good news/bad news re ABT/ABBV when issued shares:
Good news: At E*Trade, I get a free carry on the ABT.WI purchase until the “real” shares of the new ABT begin trading on 1/2/13; i.e. my account has not been debited for this purchase.
Bad news: I can’t short ABBV.WI (effectively selling the ABBV I will receive from the split-up) because there are no shares available for borrowing.
