Today, Houthi rebels blew up half of Saudi Arabia's oil production. Oil is up 9% tonight, which means GUSH, ERX, and other oil and gas securities (i.e., GE, RIG) are going to go to the moon tomorrow. I'll be buying at the open of the premarket session.
Gold and other metals should also benefit from the general sense of international insecurity, so NUGT, JNUG, and FCX are also decent buys.
