What's On: Dupont, 3M and Retail Stocks

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

--The diamonds in the Dow. We're talking about the Dow stocks with best chance for growth in the weeks and months ahead. On our list, General Electric, DuPont, Caterpillar, 3Mand Microsoft, should they be on your list as well?

--Costco out with numbers this morning, we'll break it down with a top analyst. And McDonald's has same store sales, we're on it like grease on a french fry.

--Also this morning, why good marijuana is suddenly so cheap.

--And the retailing stocks you should think about shorting. Talbot is on a lot of lists, we told you about the short calls two months ago, since then it's down 18 percent.

--Listen to Squawk on the Street, we're giving you actionable ways to make money.

--Plus, The Street Poll asks if you think the Dow is going up or down by year's end. Share your opinion and watch the big show at 9am eastern, live from the New York Stock Exchange with Mark Haines and Erin Burnett.
