Keep in mind that a few hundred global investment groups account for the $Trillions that move through our financial markets each day. When they re-allocate their investment assets they change market trends. We are getting concerned about potential large sales programs for both stocks and bonds. One of the largest groups, Blackstone (in collaboration with Backrock) waited for house prices to crater in 2008-2010 while building companies to buy $Billions and thousands of foreclosed homes.
