Demian, are you sure the selling had to be done by last Friday? This link says QQQQ has until the 24th to sell off and reconstitute: http://www.indexuniverse.com/section...rebalance.html.
So is that just QQQQ, or does every fund that follows the index have the same amount of time?
While the index always has 100 stocks, the trust running QQQQ has to add and delete names through a bidding process with market participants. These so-called rebalancing trades are due to take place in a five-business-day period, starting Dec. 18 and lasting through Dec. 24.
