Recapping the day's news and newsmakers through the lens of CNBC.
Twitter shares bolted out of its IPO starting gate, closing up 73 percent from the $26 offer price and just under $45. The social networking service's opening pop lifted the company's value to above $31 billion, about the size of General Mills and bigger than two out of three S&P 500 firms, though Twitter has yet to turn a profit. Twitter co-founders Evan Williams and Jack Dorsey, along with CEO Dick Costolo, saw their combined value in the firm skyrocket to about $4 billion.
