As I did in 2000 and 2007, I feel obligated to state an expectation that only seems like a bizarre assertion because the financial memory is just as short as the popular understanding of valuation is superficial: I view the stock market as likely to lose more than half of its value from its recent high to its ultimate low in this market cycle.

At present, however, market conditions couple valuations that are more than double pre-bubble norms (on historically reliable measures) with clear deterioration in market internals and our measures of trend uniformity. None of these factors provide support for the market here. In my view, speculators are dancing without a floor.
