S.Q.I.D. is my SPY, QQQ, IWM & DIA average that I created to simplify. Looking at the weekly chart and marking some common, analogous points (on chart) it would appear that this event is 3.33% larger. The 2011 event bottomed on the 150sma. 150sma x 3.33 = 450sma. Should the comparison hold true the markets should bottom at the end of February 2016 at the 450sma some 33% lower from the recent ATHs made this summer 2015.
