They definitely do. The market always trades ahead of news making the little guys and gals like us have to get in before the news hits to feel it's effect. Friday's increas of MM's is another good sign IMO that some kind of release is right around the corner!
of course they get news before us,otherwise they wouldnt be in business. reminds me of barrons finance magazine years ago.all the people that worked for them used to get all the hot stock tips before the public did and they they would dump all their cheap shares on us.
