You think you know your way around stocks? If you do, here’s your chance to go past talking the talk and start walking the walk. And if you’re really good, you might even walk out with a 2010 Maserati Gran Turismo->ke2326 Convertible.

CNBC is sponsoring the ‘Call the Close Sweepstakes’ to see who can guess the closing number for the Dow Jones Industrical Average and the S&P 500. For every day you play, you get a bigger chance of driving away with that aforementioned Maserati.

Sounds simple, right?

Continued after the jump.

The guidelines are pretty cut-and-dry: Active calling hours are from 4:30pm EST every day until 1pm EST the next day. And if you want to check out how you’re doing compared to your competition, you can check out the website’s Close Callers page from 1-4 pm EST so you can find out the overall standings and your rank relative to everyone else’s.

We normally try and enter just about every car contest we can find, but this one seems pretty like it involves a lot of foresight and astute awareness of the daily economic market, which, unfortunately, isn’t really one of our strong suits.

But if you guys are even remotely aware of how the stocks work, then by all means, give it a shot. And if you win, don’t forget to mention us for letting you know about it in the first place.
