TheStreet's Jim Cramer says Pfizer will pay whatever is necessary to buy AstraZeneca because of the amazing tax advantages. Cramer considers it a done deal and notes it will be finalized very quickly. Whirlpool is an interesting story to Cramer and he believes today's downgrade of the home appliances company is wrong. Cramer doesn't think the housing market is doing well, but he thinks Whirlpool is taking more market share away from Korean competitors. Cramer also likes DirecTV on its possible merger with AT&T and he says the stock is telling investors the deal will be completed. He would be a buyer of the stock below $100.
