There will always be conceptual issues with any single
valuation measure, so the best we can do is evaluate
valuations from the standpoint
of multiple historically reliable approaches.
As usual, I don't place too much emphasis on this sort
of forecast, but to the extent that I make any comments at all about the outlook for 2006, the bottom line is this: 1) we can't rule out modest potential for stock appreciation, which would require the maintenance or expansion
of already high price / peak earnings
multiples; 2) we also should recognize an uncomfortably large potential for market losses, particularly given that the current bull market has now outlived the median and average bull, yet at higher
valuations than most bulls have achieved, a flat yield curve with rising interest rate pressures, an extended period
of internal divergence as
measured by breadth and other market action, and complacency at best and excessive bullishness at worst, as
measured by various sentiment indicators; 3) there is a moderate but still not compelling risk
of an oncoming recession, which would become more
of a factor if we observe a substantial widening
of credit spreads and weakness in the ISM Purchasing Managers Index in the months ahead, and; 4) there remains substantial potential for U.S. dollar weakness coupled with «unexpectedly» persistent inflation pressures, particularly if we do observe economic weakness.
Bogle has typically used dividends as a fundamental, but sales and smoothed
measures of earnings can also be used, provided that the corresponding
valuation multiples are used.
