Went over the following article. Big Brokers Set for Fourth-Quarter Pinch Sandler O'Neill said lower trading revenue was light even for a December. Trading revenue is one of sources of profit - but not the unique source. The article particularly mentioned MS and GS. They lowered the esitmate for MS for the 4th Q, but not for GS (however no mention why they keep same estimate for GS, but at least they don't want to rise the GS view for 4th Q).
