Seems like Harvey, this week, strongly hinted at very positive ASCO data, and also (if I heard him correctly) that there would be at least some positive news in the abstracts themselves.
Guessing that we probably do fill this gap at 17.23, but that we don't fall much below that, and may in fact turn around right there.
Hang on, it's a bumpy ride back up, but I'm wagering that up is where we're going.
