Extreme Overvaluation and the Inventory Problem

Last weekâ??s advance had the earmarks of a short-squeeze, featuring a low-volume advance to marginal new highs on a number of indices including the S&P 500, on hopes that a Greek bailout and a firming in oil prices will put a floor under global economic deterioration. On factors that affect our estimate of the market return/risk profile, credit spreads remain broadly wider than they were a few months ago, and our primary measures of market internals remain unfavorable. Meanwhile, equity valuations â?? on the most historically reliable measures we identify â?? are now fully 117% above their pre-bubble norms, on average. As of Friday, our estimate of prospective 10-year S&P 500 annual nominal total returns has declined to just 1.4%, suggesting that even the dismal 2% yield-to-maturity on 10-year bonds is likely to outperform equities in the decade ahead.
