On CAPS, 99% of the 1,125 All-Star members who have rated Petrobras believe the stock will outperform the S&P 500 going forward. These bulls include MajorMiner and jamespeer, both of whom are ranked in the top 15% of our community.

Just last month, MajorMiner tapped Petrobras as a Latin way to boost your energy (exposure):

The fundamental causes of high energy in 2008 have not gone away. The lending crisis slowed demand, but the underlying imbalance is still there. I expect the US dollar to drop because of China's dollar dumping and "quantitative easing". This sets up this ADR to be a real winner.

In a pitch from two weeks earlier, jamespeer elaborates on Petrobras as a giant opportunity:

Brazil is HUGE and there are still a lot of oil fields that are yet to be drilled in this vast country. Petrobras is basically the monopoly and I believe it will become an oil colossus to rival the likes of [Royal Dutch Shell] and BP in the future. As these companies and their respective economies regress, Brazil and Petrobras will just keep growing. Big thumbs up on [Petrobras] an oil giant for the future.
