why is the price going backwards

I can't understand why the market goes 100pts and this share goes backwards. There appears to be no support whatsoever. The institutions aren't interested and sellers are pulling money out of this stock to put into other better performing stocks (which is 99% of the market today).
Sales must be poor or drugs for approval held up by the TGA - something must be up.
One to hold for 3+ years? Who knows?!
