Streetmoney21 says CME raised Silver Margins from 21,600 per contracts to 27,200 per contract on Friday Nov 4, 2011
If this is correct, we are in for a world of hurt or metal on the cheap, depending on how you want to look at it. If you were thinking about selling for any reason today is the day to do it, assuming that what Streetmoney says is correct.
These assholes at the CME are going to piggyback this onto some bad dow news that will likely come out next week. I think we're right on the cusp of a moment.
