Over on CAPS, 3,475 of the 3,538 members who have rated Petrobras -- or 98% -- believe the stock will outperform the S&P 500 going forward. These bulls include CAPS All-Star Ayax2006, who is ranked in the top 1% of our community, and djemonk.

Last week, Ayax2006 tapped Petrobras as an ideal turnaround play: "This Brazilian oil company with large reserves and important recent discoveries will easily outperform the market in the coming years, as the oil price and Brazil recover."

In an earlier pitch from December, djemonk expands on that bullish line of thinking:

Great margins, industry leader in offshore drilling and application of technology, growing market, strong government support. Petrobras is inherently ingrained in the psyche of many Brazilians through ever present gas stations, film and TV subsidies, and the fact that this is the company that put Brazil on the global arena, which contributes to its economic moat. The Brazilian Real is also currently [in my opinion] undervalued and should rebound strongly, so investing dollars into PBR should pay off when the exchange rate starts to favor the Real again.
