I wish I could go into more detail, but cannot for the sake of conciseness. PBR is extremely undervalued. Revenues and FCF have grown significantly since the beginning of operations for the company, yet it is trading as if it's moving into bankruptcy. If they begin to pay down corporate debt, shareholder value will be unlocked.
Market concerns: Brazil has 5-6% inflation and gov't seems to weigh down PBR's potential. Technicals: Volatility suggests that PBR is likely nearing a long term bottom. The largest spikes in volatility were in 2003, 2009, and now in 2014. Also, the falling wedge (bullish formation) may suggest a break-out to the upside.
Each RELATIVE entry point ended up delivering massive returns. With that said, there will be continued volatility, however $10.27 is a VERY good price in my opinion. I will most likely open a (100k) position in PBR tomorrow. LT PT: $20-$30. Questions? Comment below. Thanks.
