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

In today's installment, housing had its best year since 2006 last year, and retailers such as Home Depot (HD 0.94%) and Lowe's (LOW -0.04%) are showing it in their sales growth.

These stories, plus today's biggest movers, and two stocks we'll be following closely this week.
