Someone has.....Look at where the share price closed on Friday. Although considered not an actively traded stock its performance does seem particularly woeful even with the Friday afternoon closing price shenanigans.
Ouch! Very true, higher than normal volume, but not significant either.
It did see a bit of a sell off right after a mum and dad investor newsletter (The Motley Fool) touted Qantas' turnaround and suggesting people buy that.
With a 18% drop over 3 days you'll also find that the shorters would have been all over the stock. The day traders will more than likely be keeping an eye on the shares as well waiting for a bounce which will see an increase in the price and then another sell off while the aforementioned get out of their positions.
I don't day trade anymore so don't have access to IRESS anymore, but could be an interesting one to watch (from a trading point of view). Especially if Virgin can get Tiger to turn a profit within the next 12 months. In the meantime I wouldn't see the share price as much of a concern.
