After a strong open on an upward GDP surprise, U.S. stocks scaled back and dipped in and out of the red in midday trading Tuesday. Investors are tempering their earlier excitement on the economy after the latest reading on consumer confidence declined to 88.7 in November from 94.1. Tech stocks are making moves in the session including BlackBerry (BBRY). Shares are up more than 1% as the company goes directly after Apple's iPhone. BlackBerry is offering up to $550 dollars to iPhone 6 users, who trade-in their devices for a Passport. Apple's (AAPL) market cap broke $700 billion, doubling under CEO Tim Cook. But another tech executive is under fire for misfiring a tweet and blasting it for all to see. Twitter's (TWTR) CFO Anthony Noto tweeted, 'I still think we should buy them. He is on your schedule for Dec 15 or 16 -- we still need to sell him. I have a plan.' He quickly deleted the tweet. No word on who the message was meant for and what deal they are hoping to seal.
