U.S. stocks are rising Monday morning following a series of corporate deals. The largest by far is AT&T's plan to buy Time Warner for $85.4 billion, but investors aren't sure if the combination will happen. Aerospace company Rockwell Collins agreed to buy B/E Aerospace. Technology and industrial companies are making some of the largest gains while phone companies are lagging the rest of the market.
Online brokerage TD Ameritrade is buying Scottrade in a $4 billion cash-and-stock deal that would significantly expand its branch network at a time when many financial firms are expanding automated adviser programs.
