There were mini bull markets that lasted years inbetween there. !929 was way different though.
You have two things that don't correspond -- ( (1) If we get 25% unemployment and bread lines I think the stock market will be the least of most of our worries.
(2) A ragingbull bull market with absolutely ridiculous valuations and no margin requirements in the stock market. Kind of like NASDAQ 5000. Probably take more than 11 years to beat that mark. :) But Dow 14,400? The PEs were never out of control like NASDAQ 5000 or Dow 1929. But true, if there's massive slaughter to the economy 1929 style, then it may be 11 years before the Dow reaches a bottom.
