Interesting,.... although actually according to the E-trade chart that I am looking at right now - share prices dropped to their low point of $1.72 on about a 29K share volume, then went back up to $1.74 on a ~150K share volume, then up to $1.80 with ~2.69 million shares to close at $1.80.
Big volume,.... right at the end of the day - but from this chart it appears to have happened 'in hours' - rather than 'after hours' - and ended up taking the share price upward at the end.
Interesting,.... somebody big decided they wanted in,.... or out. We'll see how it plays out.
