U.S. stocks opened steady Wednesday as investors take in earnings, especially from the tech sector. Apple (AAPL) amazed again with a record profit report. Apple said it sold 48 million iPhones in the quarter compared to 39 million in the same period a year ago. It also said revenue was $51 billion and it has $206 billion in cash on hand. On the other hand, Twitter (TWTR) investors are getting impatient with a lack of subscriber growth. New CEO Jack Dorsey said the social media network only added 4 million new subscribers in the quarter, falling short of what investors want. Earnings continue after the closing bell with GoPro (GPRO) reporting. Investors will be looking at meaningful innovation from the company that does have a history of beating expectations. Buffalo Wild Wings (BWLD) will update Wall Street on its new technology, price increases and how the football season sales are going. TheStreet's Scott Gamm, Jane King and Rhonda Schaffler have details.
