The "Short Sell Report" recorded approx 100 million naked short sell positions attacking Silverado Gold Mines stock for the month of Aug 2012. Multiply that by months & years, the total number could be mind boggling, into the 10s of billions?
I seem to remember, from several years ago, that the squeeze trigger point was @ .01 ??, not 100% sure, maybe someone else might have heard or read of a more recent trigger point?
Whatever the trigger point maybe, the fact remains, when the massive naked short sell position race to cover, we could witness something spetacular, watching the stock price slingshot up the chart @ mach 4 speed 2880 mph!!
I've included a recent chart that shows the trend of naked short sell from Sept 13-19, the average for the six days is running about 45%
