The S&P 500 <.SPX> weakened further from a technical perspective on Friday after its 50-day moving average broke below its 200-day moving average, indicating an accentuation of downside momentum.

This death cross --a shorter-term average falling below a longer-term average-- last occurred between the 50- and 200-day moving averages in December 2007, shortly after the beginning of the market decline that eventually took the S&P 500 to 12-year lows in March 2009.
