I have researched this to no end and a fair, mean historical value for the Dow always seems to come out between 4,000 and 8,000, with 8,000 seeming the least likely because of the huge, long term bubble we have been in for the past 2 decades.
All the valuations I try to apply confirm this. PE ratios are currently a bit over 20 for the S&P 500, not the 10-15 commonly quoted on CNBC. History shows us they should fall to as low as 6 at the bottom of a severe bear market.
Book value is also about twice the mean average and should be expected to fall significantly below the mean average if we are in a severe bear market.
Here's a Valueline DJIA chart that I used. It goes from 1920 to 2006:

http://seekingalpha.com/article/90537-b ... -the-guideTo me, this is the final shoe to fall: all these "experts" on CNBC must be taught that you can't just make things up and ignore all but the last 20 years of history; all of us consumers must learn that we can't have things without working for them. This will take years and along the way our economy will suffer but we will become better for the lessons that will be forced upon us. Those that have always lived within their means and those that accept the lessons quickly will suffer the least.
My bottom line is that a drop to under 2,000 on the DJIA is possible while a drop to under 5,000 is almost certain, based on simple reversion-to-the-mean principles.
One thing about this situation that strikes me is how "it can't get any worse" and then it goes ahead and gets worse. We truly are in "The Great Unwind", my name for our very own great despression.
