I don't know how to answer that question, the Nikkei is still down 70% or so from its peak in the early 90', 15 years later, no reason the Naz, which is over inflated will not take 15 years to get back to those lofty highs. I would wait to see a real secular bear market bottom. I would suggest that would be associated with a serious recession and possibly much higher inflation than we are seeing now. The Dow and SPX are more rationally priced, but even these will have to see "uncommon values" before the secular bear ends.
