The following video is from Monday's edition of Investor Beat, in which host Chris Hill and analysts Jason Moser and Bill Barker dissect the hardest-hitting investing stories of the day.

United Natural Foods (NYSE:UNFI) continues its run after very strong Q4 results. D.R. Horton (NYSE:DHI) is among the homebuilders popping today, potentially connected with the news that Larry Summers will not head the Federal Reserve, which some think could be good news for mortgage rates. FedEx (NYSE:FDX) is up ahead of the company's Q1 earnings report coming up on Wednesday. And Boise (UNKNOWN:BZ.DL) jumps up big on news that Packaging Corp. of America (NYSE:PKG) has agreed to buy the company for just shy of $2 billion. In this segment, Jason and Bill discuss four stocks making big moves today.
