Volume.. maybe people are anticipating good earning will be released next Monday, Mar. 11.
Whatever it is, ps going up, volume are way higher than avg 3m volume and chart technical indicators are showing up trend, RVM should see $2.20 maybe tomorrow.
Fact is that everyone know that FDA delay could take a few weeks (stated in last released).
What news should there be in the meantime?
ZGNX should continue to go up above $2 and probably settle at $2 until FDA decision.
I based $2 on millions of shares is being held by insiders or institutions. You can see insider info by quote in nasdaq and click insider.
