What's On: Wal-Mart, Homebuilders and GM's IPO

Here's what's up on Tuesday's Squawk on the Street:

--Wal-Mart beats estimates and says it's fairly optimistic about the holiday shopping season.

--A key report on housing prices comes out this morning. We're looking at the housing market and homebuilders including Lennar, KB Homes and DR Horton.

--Also coming up, getting ready for the GM IPO. We have the owners of three GM dealerships to show us where they stand. They've all been offered shares in the initial public offering, but they didn't all say yes. See why.

--Also on the GM front, the new man with the message, the executive in charge of marketing. He came up with some great campaigns for Hyundai, now see what he's brewing up at GM.
