Index changes were not uncommon before 2001. S&P announced a change on random Wednesdays at market close in those years.Then how do you justify the fact that the companies on the tail end of the 500 were not replaced very frequently before 2001 ? Surely the difference in capitalization between #500 and #501 is less than the daily volatility.That is only for inclusion. This filter was added after the dot.com bust.
