$GameStop(GME)$$BlackBerry(BB)$ Both went down steeply at the same time. Maybe it's computer selling or big holder letting go of their stake.... For what purpose? To push down the price? A chance for others to buy in, maybe.
$Atossa Genetics(ATOS)$ hang in there. Don't sell down. Internet commenter said that come summer time, Atos will release their nasal spray, so price might spike then.As for current fall, it might be cause of their submission for Warrant exercise. Google S-3 form submission.
$BlackBerry(BB)$ yahoo reported bullish sentiments for the stock because of options with strike price 23usd expiring 19th March.So perhaps we can hold and look forward to it.
