    World Champion Poker player Chris Moneymaker is in Monte-Carlo for a poker tournament, but that didn't stop him from talking with CNBC's Erin Burnett and Jim Cramer on "Squawk on the Street" about his contest strategy. Chris is in 3rd place as of Monday's trades but he said today that "being in second place, you might as well be in last."

  • Ryan Stackman

    Ryan Stackman is 23 years old, just out of college and never won anything before--but he's now our third weekly winner for the contest and has won $10,000--and qualified for the finals. Quite an accomplishment. I spoke with him by phone today and he says he's happy but surprised he became a weekly winner. His family and girlfriend share in both feelings.  (FYI--see Ryan interviewed today at 1:30 pm EST on "Power Lunch.")

  • Most of our celebs had a slow day Monday, but James Cromwell "has been a machine" as someone said. Not only is he buying stocks, he's putting those bonus bucks to work--something the other celebs--and you non-celebs should be using to your advantage. Willie Garson used them to put Johnny Bench back in last place.

  • Hey folks. Here's the best performing trades by % gain from Friday's close to Monday's close: Biosite--If you bought on Friday at $55.38 and held/sold on Monday with a close of $83.80, the contestant gained 51.32% on the trade (9 out of the 10 current weekly leaders as of Monday's close bought BSTE on Friday).

  • Good morning. Here are the latest names and numbers from Monday's action. Deborah Taft continues in the lead with a portfolio value of $2,216,726.30. Her biggest portfolio gains continue to be in the ever popular Fremont General which she sold out of completely on 3/21. She made $23,062.62 or 1.05% on buying and selling 164,733 shares of Elan Pharma.

  • Hey folks. Here's a belated look at the latest leaderboard standings. Deborah Taft is on top once again after Friday's action. She's followed by Chad Mazeika from Illinois who is back in the second spot--as the former number two, James Meisner is now in the fourth spot. Some new names are on the board, while some old ones remain. You'll find the top 20 listed....

  • Time now for our weekly webcast program (every Monday) to go over what happened last week and what might play out this week. Remember, it's the start of week four--as CNBC's Dylan Ratigan pointed out. Dylan went over the big gainers from Friday (traded on Thursday) as well as the biggest losers and the most actives. So--here's the info...

  • Ryan Stackman

    We have another weekly winner to announce. He's Ryan Stackman from Pennsylvania. Ryan becomes the third weekly winner. His strategy for the week was simple (or not)--buy volatile stocks by looking at earnings and/or unusually high volume. Ryan says he one stock he picked that surprised him was Synnex Corp. He is a stockbroker by trade--

  • We mentioned earlier today that Stephen Collins has moved up to number one in "Trading With The Stars." Here's a breakdown of where each celeb stands as of Friday's action. Remember--the stars are playing for a chance to give their favorite charity a $50,000 donation. Sorry to say that after a brief stay in 9th place, Johnny Bench is back in dead last.

  • Chuck Chow

    Second week contest winner Chuck Chow appeared on Friday night's "How To Win" program and talked about why he picked the stocks he did. Our experts were able to "critique" his approach (not so needless to say--they thought he did just fine!). Chuck nearly doubled his portfolio value in just two weeks. His picks were FMT, FSLR and Gymboree.
