  • Stephen Collins

    Actor Stephen Collins is almost in 7th Heaven (his starring TV show) again--well, at least he's in 3rd place in the "Trading With The Stars" contest competition. He was in in fifth place on Monday. he needs only $3,000 more value in his portfolio to climb into second place--

  • Judy Gold

    Judy, Judy, Judy--HELLO!. You're in 6th place after Tuesday's "Trading With The Stars" action. That's after you were in 4th place on Monday. Okay, Judy's had two days of falling value--something that did NOT go unnoticed by CNBC's Michelle Caruso-Cabrera on "Morning Call." That's the show Judy's playing for--at least the first hour.

  • moneymaker_chris_150.jpg

    Celeb and champion poker player Chris Moneymaker is in second place in "Trading With The Stars." But that isn't keeping the crew from "Squawk on the Street" from giving him some specific stock pick advice. CNBC's Erin Burnett talked with Bob O'Brien, who had some stock picks based on Chris's criteria (keeping his picks at the contest rule market cap of $500m)

  • We've got some of the latest contest statistics on most active, widely held, etc.  So, without any further introduction, here they are. The numbers are as of Tuesday, March 20, 2007.

  • Here's our current celebrity standings for "Trading With The Stars," and what they've been up to. Not much difference from Monday, as the top three spots remain the same. But Judy Gold is slipping down a bit. She was in 4th place after Monday's action, but is now in 6th from Tuesday. James Cromwell moves up to 5th from 6th.

  • Good morning. There was a flip flop in the top position from Tuesday's results. Domenico Vicario is the new leader with a portfolio value of $1,955,972.11. Domenico reclaims his top position with the investment in Comtech Group up +3.27% from 16.53 to 17.07.

    Who says the CNBC show hosts aren't really into the "Trading With The Stars" part of the Million Dollar Challenge? Okay--I haven't heard anything like that yet, but I'm prepared if I do. But--yes, the show hosts are rooting for their celebs, if Michelle Caruso-Cabrera and Liz Claman are any indication. Remember, each celeb is assigned to a CNBC-TV show to win..
