QE doesn't ensure rising stock prices, just higher stock prices than where they would be otherwise. In short, the bottom of the dip is still propped up by QE.
Think of it like this. If another billion barrels of oil start getting purchased every year to go into a stockpile somewhere, that isn't going to ensure that oil prices never dip going forward, but it will mean that they remain higher at all points than they would have been otherwise.
This is where I get left behind.
For me, measuring things that exist is hard enough and pinning down could-have/should-have/would-have is just more trouble than it's worth. Let's all enjoy our own private cherished opinions knowing that no proof exists for or against.
