John Hussman, here, last Tuesday:
'While we can make our case on the basis of fact, theory, data, history, and sometimes just basic arithmetic, what we can’t do – and haven’t done well – is to disabuse perceptions. Beliefs are what they are, and are only as malleable as the minds that hold them. Like the nearly religious belief in the technology bubble, the dot-com boom, the housing bubble, and countless other bubbles across history, people are going to believe what they believe here until reality catches up in the most unpleasant way. The resilience of the market late in a bubble is part of the reason investors keep holding and hoping all the way down. In this market cycle, as in all market cycles, few investors will be able to unload their holdings to the last of the greater fools just after the market’s peak. Instead, most investors will hold all the way down, because even the initial decline will provoke the question “how much lower could it go?” It has always been that way.'
