I sincerely doubt that what the tweet link purported to be true regarding a
"comment made at dinner"
had any basis in fact. Did the 50K+ followers of @Biohazard3737 (aka "Sheep of Wall Street") believe it or merely think they could daytrade on it to make a profit and that had something to do with the stock movement? Maybe, but I think the tweet was made up BS.
I heard that claim to fame recently on a message board entirely unrelated to biotech. It was met with similar skepticism and zero backup nor follow-up in terms of real news.
Yes, sometimes serendipity leads you to hearing things not meant for your ears, but don’t bet on it, especially if you didn’t hear it yourself.
