20081017 The end of a historic tumultous week for the S&P 500 futures, where options expiration takes effect today. The Dow closes with its best ever positive performing week, while on Wednesday, it saw its biggest ever plunge since 1987. Friday's closing and trade is more governed by this than anything else. What I suspect is that stock indices will be traded in the range set this week.
