Today Morgan Stanley came out a research report where they shared their sum of the part valuation estimates and the assumptions within that.
May be MS is not part of the deal. Also, MS had a high PT all along, so they may be they are trying to set some floor for the deal price. Coincidently, today $AES moved up 2.75%. My own expectation is if $AES is taken out, it will be at least around $15+.
