In Aug last year just days before the FY14 results it dropped form $2.70 to an intra day low of $2.11 in 3 days before heading back up again. Volume was 315k, 213k and 905k over those 3 days.
This time they are falling from a much more overvalued price. But just looking at yesterday and today, it has fallen from $3.30 to $2.70 on volume of 192k and 540k so far today. Not out of the ordinary volumes compared with historical sell offs (which didn't last long)
