It's baffling people don't understand the basics of trading volume.
This has traded 3 million shares on a 1.2 billion OS. Its twice the daily volume which is nothing. Today's increased is simply speculators trading another GBM stock on the NVCR news.
NVCR is trading 10% of it's OS on it's news. 10 million traded on a 107 million OS. THAT'S what trading on news or information looks like. Simple concept.
There have been plenty of days where we had large moves day after day with volume that was not so much greater than the daily volume. 10M is not necessary. This stock has frequently had runs and sags in the past based on shockingly little volume. And except for a few occasions the volume has really never moved to the kinds of volume I have seen in other stocks yet still had dramatic moves up and of course down. The volume has always been tight with lots of large holders sitting on large amounts of shares.
