In this segment from Wednesday's Investor Beat, Motley Fool analysts Bill Barker and Jason Moser each look at one stock they'll be watching closely this week. Bill looks at Costco (NASDAQ:COST) and discusses why it will make a good barometer when it reports earnings tomorrow for how this year's exceptionally severe winter weather affected retailers as a whole, while Jason will be watching Craft Brew Alliance (NASDAQ:BREW), a small brewer with a lot of big connections.
