Not only conclusions but the data that was used to arrive at those conclusions. What was the base period used for comparison to the period after the ban went into affect, and why was that paticular base period selected. Surely another base period could be found where just the opposite conclusions could be drawn.
LOL, that sounds like a mutual fund performance report. Boy, fund managers will all be happy when the 2000 crash comes out of their 3 year performance base period.
