I agree with Rumbled. To my mind its pretty obvious that hes increasing his headroom so that he can convert the loans into shares without crossing the 30% threshold necessitating a bid.
Have faith Poptimist. As Kiwi posted yesterday IQAI which I have held for 18 months similar to ARB sat at about 4p until 2 days ago when people finally woke up to its potential. It gathered traction ( and unwanted day traders ) and is now consolidating around 400 % higher. I am certain that the same pattern will be repeated here.
