Rather than discuss a bunch economic issues and current monetary policy on reasons this is more likely than not I will just post these numbers and let everyone make there own conclusions:
S&P 2007-2009
Top to 1st major low: 161 days 20.53%
Bounce and rejection of 50 MA: 63 days 14.58%
Top to bottom: 511 days 57.12 %
S&P Current
Top to most recent low: 161 days 24.79%
Bounce to current rejection at 50 MA: 63 days 19.39%
One interesting component is the anchor vwap from 2009 low is tracking to come close to that ~57% range from the current top... Could be nothing or could be something... maybe
