The crux:
"We have not developed any evidence that suggests
that those who had advance knowledge of the attacks
traded on the basis of that information. In every
instance where we noticed unusual trading before the
attack, we were able to determine, either through
speaking directly with those responsible for the
trading, or by reviewing trading records, that the
trading was consistent with a legitimate trading strategy."
