LOL.. I can't even multiply 3.8x2 and i fancy myself as a investor :-)
Nevertheless, if one takes the (lower) figure of EPS FY13 at 7.2c... a PE of 5.76 is low by any standards. (at 7.8c it's just above 5.0!!). Buy on dips, hold until 55c and then consider carefully the risk/reward ratio. A couple of decent contract wins can move SP significantly.
