If you want to make a lot of money fast then you have to be willing to lose a lot fast.

If you want to play then sign up with a broker that will let you trade options like http://www.optionsexpress.com .

Buy some calls in a great growing company like Google (GOOG) or Apple (AAPL).

If you don't want to be too risky then read up on options and also buy some puts with the calls to protect yourself a little bit.

The market looks strong now and Google and Apple calls have a good chance to double in the next couple months if not triple. But it's RISKY!
