Intermediate stages: 1961..22.....1962..15......32% 1964..19.....1966..14......26% 1967..18.....1970..13......28% 1971..19.....1974....7......63%..inflation goes from 3% to 12% 1975..12.....1980....7......42%..inflation goes from 5% to 15% My chart ends in 1998; I don't know the 2000 peak PE. Do you? (It was around 35, I think.) You are right, the last secular Bear had a sawtooth pattern of valuation changes, stretching over 2 decades. During most of those years, the PE was either increasing, or holding steady at a high plateau. The low valuation wasn't hit till 13 years after the peak. And then that low valuation was retested 6 years later, before the secular Bull market started. The market PE is strongly correlated (inversely) to inflation. In the 1961-1980 Secular Bear, the peak PE in 1970 was only slightly lower than the secular peak back in 1961 (19 vs. 22). The massive contraction in PEs (down to 7) was accompanied by a massive increase in inflation in the 1970s. Inflation troughed in the 1-2% range, in 1961,1987, and 1998. I'm about 90% sure that 2002 will see another inflation trough, in that same range. The first two of those troughs correlated with multi-year PE peaks. In 1998, the inflation trough correlated with a return (for the first time in 37 years) to the 1961 valuation levels, before going on to the Bubble Peak. So, I don't expect a secular bear, and I don't expect a return to single-digit market PEs, unless I see signs of resurgent inflation. Based on where the market PE has been when inflation was in the 1-2% area, I'd expect the market PE to be in the 22-15 area in 2002. That's using trailing earnings. Which raises the question of whether Creative Accounting, and the difference between GAAP and Pro Forma, is greater now than in earlier decades. If so, then all the data above is skewed. I don't know the answer to that question. At the earliest, I see inflation as a 2003 problem. IMO, we can forget about it till then (the Fed has, by word and deed). Which means, based on the consistent pattern of the last 40 years, that we shouldn't expect a big decline in market valuations in 2002. Which contradicts my expectation of a PE in the 22-15 area. Which leaves me uncertain. BTW, the other scenario that leads to a single-digit market PE, is the 1930s pattern: deflation, protectionism leading to a collapse of world trade, political instability thru most of the large economies, a collapse in consumer and business spending/confidence lasting 10+ years. I see no chance of those conditions recurring.
