Stocks added to an advance yesterday triggered by government data showing unexpected growth in durable-good orders and new-home sales. Those reports tempered reaction to Commerce Department data today that said the economy shrank last quarter at a 6.3 percent annual pace, more than previously estimated while less than the average forecast in a Bloomberg survey.
