The CNBC Investing Club with Jim Cramer discusses the stock market on Friday, with the Dow slightly down and the S & P 500 and Nasdaq both higher. While Cramer expressed a preference for a broader rally, he criticized the heavily weighted tech sector for not investing in other areas. He recommended Corning ahead of next week's earnings, noting that the company's stock has been on a rise year to date and its CEO, Satya Nadella, has begun addressing issues with the company. Cramer also commented on the potential demise of Fed Chairman Jerome Powell, which removes a barrier to his confirmation. Nine other Club names are reporting earnings next week, including Microsoft.
