Markets Stop On A Dime And Shoot Upwards – S&P Rallies 25 Points In An Hour
Well, well, I have no idea why but: S&P 1 Day Chart.
UPDATE (Wed 10/24, 8:45pm PST): It seems that the reason for the late day surge was rumors of an emergency rate cut from the Fed (subscription required, free).
Why the Fed would step in in a panic today, when they are scheduled to make a decision next Wednesday, is beyond me.
