CNBC Million Dollar Portfolio Challenge

CNBC starting an investment game for real cash prizes.

Beginning on March 5, 2007, CNBC is starting the Million Dollar Portfolio Challenge where you can sign up and create a pretend portfolio. At the end of each week, the winner will win $10 000. After 10 weeks, the 10 weekly winners as well as the top 10 rankers will have another chance to compete at the $1 million grand prize. You can also get extra money to invest with by doing daily trivia and referring friends to play the game too. Sounds interesting for people who love to take risks and have such a large sum of money to invest with!!!
