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

OPEC's big meeting in Austria. We'll watch the oil stocks closely including ExxonMobil and Chevron.

--Plus, Meredith Whitney making new comments about muni-bonds. See if she's softening her dire warnings issued earlier this year.

--We have the CEO of Life Technologies. This company has been instrumental in helping European authorities with a deadly e-coli outbreak.

--Also on the big show, we're making stock pickers tell us what they're picking between now and Labor Day. Will this summer really be a stinker?

--We have another cloud CEO on the show talking about the chances of a hack attack on the server that holds all your stuff. The CEO of 8x8 will be with us.
