Why own a resource extraction company that has no hope of replacing it's production.   Oil is increasingly the property of the country in which it is found, a paradigm shift of catastrophic proportions to the E&P world, particularly the majors.   Soon they will be reduced to doing contract extraction work, not the past model of exploring and producing for their own account, minus a "royalty".  Even the Canadians are now getting very nationalistic about oil - note today's story about Newfoundland refusing to let XOM and another major (Shell, I think) roll over them and threatening to cancel existing contracts.   Sounded like Venezuela.  And this from our northern neighbor.   I can't imagine wanting to own a major oil company when there are so many more attractive ways to play the future of oil.   By the time oil is over $150, the majors won't have any left to sell.
I agree. Many oil stocks ("growth" investments) will need to be re-priced -- i.e. as bond-like investments ("return on/of capital" investments). Energy production trusts are already priced this way and may be a better "investment" on that basis.
