The premium in PSLV just went negative today to -.05%.  First time this has happened since the trust was launched in Oct 2010.  This is a physicalsilver trust and unlike SLV ones PLSV units can be redeemed for physical silver (buying physical silver below melt?).  Hard for me to make sense of this given the high premiums on physical silver coins and bars.  Anyone have any idea what's going on?
