I find your analysis fascinating as well. Great post. I think when I combine your analysis with the following article from The Motley Fool I have the best understanding. Maybe what you are saying is typical for stocks like AOL that have been added to the S&P 500. I think this will be a tough few weeks followed by a split announcement... followed by what I hope to be a fantastic earning report. I think January will be a period of establishing some sort of base in this regard followed by news and a fantastic February. (IMHO). Modano : ) AOL Long. Here is the bulk of that Motley Fool article:fnews.yahoo.com "Today's game is "Changing the S&P 500," and the target match features America Online (NYSE:AOL - news) , which is being added after market close today, and Venator (NYSE:Z - news) , which is being dumped. Based on research conducted by economists Anthony W. Lynch of New York University and Richard R. Mendenhall of the University of Notre Dame, for the period 1989 through 1995, stocks going into the index gain an average of 3.2% on the day after the news of the change and an additional 3.8% before the change occurs. These stocks usually spike the day of the change (that is, today) as money managers mimicking the index rush to take positions. The jilted stock drops by 6.3% the day after the announcement and another 12.7% before the actual change. As I've discussed before, the growing importance of the S&P has actually exacerbated these swings. Since December 22, when S&P announced this latest move, AOL has soared 18.1%, from $122 3/4 to $145, while Venator dipped 12.1%, from $6 13/16 to $5 7/8, before recovering to $6 3/4 today. Venator's rebound is interesting because the Lynch-Mendenhall study found that stocks deleted from the index experienced a permanent negative price effect of 14.1% to 15.7%. In other words, with a bunch of fund managers no longer obligated to own these issues, the demand curve shifted, cutting the price. However, the day after the S&P drops a stock, there's typically a recovery of several percentage points as the selling pressure ends. Given that Venator had already plunged from a 52-week high above $27 and much of the tax-loss selling had been done before the S&P news came out, the index-related selling appears to have enticed bargain hunters to bite, figuring all the bad news for the year was out and bounce was on the way. AOL investors should note, though, that the Lynch-Mendenhall study also showed that stocks joining the index typically dropped by about 0.75% the day after being added and another 1.25% over the next week, though these issues still end up trading 5% above the levels seen just prior to the S&P's announcement. Merrill Lynch tracked index newcomers during the 1990-1998 period and found that these stocks underperformed the index for up to a month after being added, with the 30-day underperformance rising to 8.5% this year, in line with greater outperformance in the week leading up to joining the index. That suggests AOL could have a tough month ahead, relatively speaking. One potentially mitigating factor, though, is that since the S&P index is market-cap weighted, and AOL is much larger than Venator, money managers may have to sell down their other index holdings to buy enough AOL. That could push the overall index down. At least, that's the speculation. It will be interesting to see if that's how the game plays out."
