I bought OIH near the open on price action and it's stayed in positive territory, which is good, but I don't like the feeling of not knowing what drives the price of co's like Halliburton, Schlumberger, etc. The price has been swinging around rapidly and I guess I'm asking how closely it's linked to oil prices, interest rates or any other external factors that might be moving this as well? (My timing: ideally, I want out today or tomorrow.) Also, where do you find the price of crude/futures in one of the free sites like Yahoo, CBS, etc. - didn't have much luck?
