Glenn, I think more noteworthy is the NASDAQ is down huge as is IBB/XBI so NVAX's move is anti-downward momentum so far. There was huge activity which eventually pushed this over $8 so who's buying into this binary event?
Well, they (Mizuho Securities) must have felt "strongly", after the CRL for ZS-9, that RLYP would be bought (or even before ?). She did her part by getting the "sell" out there which helped lower the PPS Anyway, that director that bought 30K in March did OK.
