movie out? i'm joe johns in for jake tapper. we begin with the money lead. we're not sure if an angel got his wings when the closing bell rang on wall street a few moments ago, but there are certainly some stock portfolios out there ready to take flight. the markets enjoyed a huge post-christmas boost, setting the stage for a year end rally. cnn business correspondent zain asher joins us live from the new york stock exchange with more. zain, why does it always seem like investors end up on santa's nice list this time of year? >> i know. december is traditionally a very good month for stocks but yes, this is the 50th record close that we've had so far this year. not necessarily a surprise, especially given the rally that we've seen in the last six trading days. one thing to note, though, is that volume was certainly light today, given that it was the day after christmas. roughly around 230 million shares traded. it does sound like a huge amount but it's actually not that much in trading terms.
