Investing or Money Pyramid
There was a 6500 point drop from the highs of 2007 to the lows of 2009. We had a 50% rebound. It is not uncommon for there to be another drop the same as the first. That would put the dow to 5000.
The dow at 5500 is one of the extreme low numbers I have talked about.
The volume is part of the reason. Less volume means less skimming by the corporations. With out skimming they have to actually pay there directors with real money. This cuts into profits.
The profits would not be there if it were not for investors.
