As I've been saying for a long time: There is zero evidence that markets can make or sustain new highs without some sort of intervention on the side of central banks. None. Zero. Zilch.
And don't think this is hyperbole on my part, I will present the evidence of course.
In March 2009 markets bottomed on the expansion of QE1 which was introduced following the initial QE1 announcement in November 2008. Every major correction since then has been met with major central bank intervention. QE2, Twist, QE3 and so on.
