If you look at the block trades, you will see that Credit Suisse are doing some major year end house cleaning and have moved out of almost every one of their precious metal stocks including Rubicon, RIO, SBB, SSL, Romarco, Primero, PSS, PG, OCA, BTO, Mag Silver, LSG, KGI, FSV, DPM, CSI, CGG, CGA, BAA, and ARZ. This might explain the recent price volatility.

Not spamming but if anyone is interested, the only gold stock that they seem to have moved into is Argonaut. GLTA
