In 2011, SLV can lose <50%> in just the month of May. Sell if May usually refers to stocks, but in this case, also SLV.
Anyone knowing the SLV bottom will profit handsomely. This is not normal selling, as some fuel was added to the fire. Must be the margin rising requirment. CME only wanted traders that can pay up in case silver falls. Therefore, credit for silver falls goes to the CME.
