I have to assume that wave X bottomed on Oct 4 @ 1,074.
And the final wave Z is in progress.
And since the expected price movement is much less, the ECM turn date of June 6, 2012 looks like a good candidate for wave Z to top.
It forms certain Fibonacci time relationships with the Mar 2000 and Oct 2007 tops.
Oct 2012 remains an alternate choice.
