I think its bit risky to invest in oil and food sectors and its even riskier to invest in financial sector as you can see this ups and downs. Banking sector? you never know when europe is going to collapse. If I were you I would go for mining, technology and hardware or something stable like research and consulting sector likewise Odyssey Marine Exploration. If I have to choose oil I would go for BP because it  is less likely to affect from the middle east crisis.
