Mainframes Continue Driving the Bulk of IBM's Growth
IBM posted higher second-quarter revenue growth than analysts expected Wednesday, causing its shares to jump more than 4 percent
• But the 2 percent revenue gain was driven primarily by sales of mainframes, not the company's key strategic businesses around newer tech, such as cloud, AI, and security, Bloomberg reported
• Still, the cloud business did grow 18 percent during the quarter and so did the Watson group within IBM's broader cognitive solutions unit, the company said
