Well here’s a question. Why from 1970 until about 1995, the DJIA more or less increased at about the same rate as the GDP but then from 1995 to 2000 it surged up 3 fold? Does it make sense that the stock market would increase that much faster than the actual the economy?
The answer, of course, is the dot-com boom. It wasn’t just dot coms though. The combination tech stocks quickly rising in value and the sudden availability of online trading basically caused all stocks to to bid higher. There was a partial correction in 2002, but then they shot up again.
Assuming that the DJIA increased at the same rate as the rest of the economy from 1995-2008 (about 3% on average), I would predict (using my crude calculations) that the fair market value of the DJIA would be in the high 6000s.
Of course, irrational pessimism may push it much lower than that, but I say 6000s is the bottom.
