The Dow's penetration of the Nov low was minor and the S&P is still firmly above its Nov intraday low (at 741, closed at 778). However, the S&P is currently positioned to break below the weekly close low from Nov at 800 which was also the 2002 bear market weekly closing low. If unable to finish back above this level, it would mark the lowest weekly close for the S&P since April 1997 and also generate a signal on a weekly basis.
