Obviously the institutional money...............doesn't believe the increase in the price of crude is sustainable. They are running up the price of crude futures ahead of the inventory reports and selling oil stocks to unsuspecting retail investors.
When the 'surprise' build in oil inventories or gasoline inventories is reported tonight and tomorrow, oil will drop, stocks will drop assisted by institutional shorters and retail investors will panic and sell.
So why is NBZ dropping while oil is rising? The increase in the price of oil is not believable.
