$80 a barrel overnight possible.The fighting between Saudi Arabia and Yemen could escalate. Iran could possily get involved with Saudi Arabia as well, which could cause the price of oil jump to $80 a barrel overnight The price of Leg would go up with the price of oil and Iran getting involved would mean the biggest producer in the middle-east (Saudi Arabia) would be directly effected as Iran would try to cut off the exporting of oil through the Persian Golf. This would drive the price of oil up.
Between October and November 2014 oil was at $80 and LEG was at 5.00.
