Prudent risk mngmt for the $100 million plus short
position in PVG just prior to the Aug 11 news would be to hammer the stock leading into the news event ... this gives them the added to cushion to cover in case the news is well received ... if the news svcks, then they don't have to sweat as much ... shorts got a little lucky this time with the US payroll news slightly exceeding expectations - which popped the dollar.
