I think more to do with Bernake's comments that Fed will scale back on bon buying. Drop in pps coincided with the timing of overall market pull back. The overall equity bullishness can't last forever. Stocks like INO aren't immune to the overall trends of the market. IMHO though that doesn't warrant liquidating one's equity position at all...quite the opposite. Broad market pullbacks present an opportunity to dollar cost average down. Regardless, I would expect INO to advance in a choppy fashion in anticipation of HIV news. And then? Green, green, green.
