I wouldn't get too excited just yet. There were only two after hours trades and the one that pushed the share price up to $7.15 was only worth A$1700.
16:42 $ 7.15 218
16:01 $ 6.89 1,999
I doubt the CDI's will be jumping 7% based on $1700 worth of shares. Not that i will be complaining if they do..
