keyser1,
I have personally made millions playing S&P rebalancings. I understand the game better than anyone. It worked great until the last few years (when even the dumber hedge funds finally caught on). Now that everyone is doing it, the risk/reward is not so impressive. But you misunderstood the original question anyhow. The rebalance that takes place this friday is actually a reweighting of existing S&P stocks, and NOT a new addition to the index like YHOO in your example. In this reweighting game, you are gaming ETF's and indexed mutual funds who have access to the very expensive reweighting data (index alert). You have to calculate the reweightings yourself and then place your trades early and sell to these mutual fund guys upon the announcement.
