The most hostile subset of market conditions we identify couples overvalued, overbought, overbullish extremes with a breakdown in market action: deterioration of breadth, leadership and other market internals, along with a shift toward greater dispersion and weakening price cointegration across individual stocks, sectors and security types (what we sometimes call “trend uniformity”). The outcomes are particularly negative, on average, when that shift is joined by a widening of credit spreads. That’s a shift we observed in October 2000. It’s a shift we observed in July 2007. It’s a shift that we observe today.
I should be clear that market peaks often go through several months of top formation, so the near-term remains uncertain. Still, it has become urgent for investors to carefully examine all risk exposures. When extreme valuations on historically reliable measures, lopsided bullishness, and compressed risk premiums are joined by deteriorating market internals, widening credit spreads, and a breakdown in trend uniformity, it’s advisable to make certain that the long position you have is the long position you want over the remainder of the market cycle. As conditions stand, we currently observe the ingredients of a market crash.
