On the thought that oil may well go to $100, I bought a small position in Marathon Oil (MRO) which has a high beta. I may buy some April calls as well.
After one month, oil is up from $80 to $90. MRO has gone from $18.30 to $21.70 (+18%). I bought the April 18 calls at $1.71 and they are currently trading at $4.04 (+135%).
