The morning of 9/11, before the Markets were offically cut off, the Really Big Players sold off their stocks ahead of others and bought short term T-Bills. As this Treasury Notes matured in the '93 & 94, they were invested back into the market and allowed the market to rebound to present highs.
There was some mention of names, they escape me at this moment. Keep in mind that they were allowed to sell off before anyone else. This was the ultimate sell high, buy low.
