In addition to all the already highlighted factors (margin hikes, Cramer buy recommendations, Chinese slowdown concerns, etc.) another possible reason why silver holders (at least of the recent variety, those who have been long since ~$10 could not care less) recently have had a difficult time with estabilishing positions in a suddenly very volatile silver market, is that according to a recently released 13-D by Sprott Asset Management, the head of the world's first silver physical ETF has taken profits on over 1.6 million shares of PSLV, across various funds, for total proceeds of just over $35 million, including up to $6.4 million for personal gain by Sprott.
