twelve year distribution dome patter emerges with highly irregular inverted peak

This is the greatest development this week that I have come across.  The week of March 9th 2003 the lows of the tech crisis in the dow were reached.  There then began a major quantitative easing, and rise in the index until 14000 in october 2007.  Then a crash to march 9th 2009, exaclty 6 years later.  now we have retested 13000 on the dow and came way back from that.  On the ten year chart there appears to be a 12 year distribution dome starting march 9th 2003 with an inverted peak march 9 2009 at the 6626 dow low.  what is the significance of a twelve year distribution dome with an inverted peak?  Comments welcome.
