Make sure you invest in the BRIC (Brazil, Russia, India, China) countries. These emerging markets will net you more that 15% in less than 2 months. Also, look into alt. energy and be ready to short oil. It will go alittle higher, but will eventually fall back to somewhat normal prices, so you can make a killing.

PS- look into diversing your portfolio. The market this day and age raises and falls fast, so being safer and netting less (both postive and negative) is far more effective than being risky and losing alot.
