Teva Pharmaceutical Industries issued a weak quarterly report yesterday, and now the bears want to savage the Israeli drug maker.
optionMONSTER’s Depth Charge monitoring system detected the purchase of almost 2,500 August 42.50 puts for $3.80 and $3.85. Volume was almost quadruple open interest at the strike.
