I'm interested in what this first week of April will show us. I think that the markets will start to decide which direction they are headed for the next couple of months. Looking back at last year, this time was fairly positive, and oil prices headed higher. But all of that set up to a decline in early to mid summer. I do think that oil prices are going to continue higher. I've been positive on refiners mostly rather than oil services. If you're going to look at a driller, concentrate on offshore rather than land drillers.
Here is a nice article about Warren Buffett and his current views on the market.
