RE: Disappointed with this ETFI don't agree with your math. If the price of oil drops from $130 to $100, the % change is 30*100/130=23.08% (not 30% as you say).
Anyway, here's hoping oil continues to decline for the benefit of HOD holders and for the benefit of world economies. I feel $90/Bbl is a fair value for both producers and consumers while still encouraging conservation.
