With Nymex Crude crossing $120 yesterday, some economist predict $200 is possible before the years out. With the strength of the £ we should use this purchasing power to buy into US oil exploration companies. There many gulf coast oil and gas companies that explore sites that become more and more productive as oil moves up. I've monitored daily price moves of 30-50% as people start buying into this sector. A lot of companies are undervalued based on proven reserves, however there are many companies that should be avoided. Do your Due Diligence and invest what you cn afford to lose!
