They are not competitors. SLB is a oil and NG drilling service company; SDRL has the most modern off shore drilling fleet in the world.
SLB has an aggressive stock buy back program and is a good investment; SDRL has a load of debt that I feel is manageable.
You should own both, or better yet own XLE
Thank you Sir. The headlines this AM are "Crammer Says Sell SDRL". How can someone make all that money and garner all that fame for shooting his irresponsible mouth off? The market seems to have ignored him.
