Could be up 200% or 500% but we still have to trade based on our thesis at the time. lol is the best way to sum it up
By the way, I'm sure you did notice there were heavy volume in last 2 days before this announcement driving the stock down 20% or so, I have no doubt there were insider trading going on, at the same time I also have no doubt ASIC will never investigate it.
Happy hunting
