Stocks World - How far can we drop?

For those who have been following the stocks market, I am sure you are aware of dropping trend current experienced by Dow Jones Industrial and the TSX/S&P composite index.

TSX, cumulatively dropped 142.83 points since the Market open on Monday, October 15th. There were many reasons to this sudden drop, on the list is the BoC (Bank Of Canada) maintaining its interest rates without a cut or a raise, another important drag is the neighbor’s Dow Jones.
The Dow dropped a cummulative of 180.14 points since the Market reopen on Monday. On the list that of reasons, the one that stood out for me was Bernanke stating that the sub-prime problem is having a larger impact that it should and the funds  established by banks to regain the credit lost in the sub-prime problme… So, really, only one problem, Subprime!
