Tiffany's, Hewlett Packard Prep Earnings, Jim Cramer Likes Unilever

There are still more companies announcing earnings as we countdown to Turkey Day. Getting ready for the open today we're waiting on Campbell Soup and DSW Inc. to announce earnings -- but that's not all. Tiffany & Co. will report its pre-holiday numbers today before the bell as well, and with its gains this year, next the jeweler will look for its upcoming quarter to shine. Plus, after the bell, Hewlett-Packard -- which is set for a split -- will announce earnings, and is looking for a boost. Finally, Jim Cramer is buying into Unilever, after shares took a mid-year dip.
