how... did they not sell it for a higher price??? i doubt it
If the purchases he made drove oil to a record, when they sold it by definition they sold it for less than they paid.
The odd think about this story is that the company apparently has such loose controls that an employee without authorization has access to $.5B in company money.
Oil was around 35.00 barrel when Obama became President. Can anyone imagine oil going to 35.00 again.
