Not being real clued up on overseas stocks or with the OTC, I was wondering if someone could explain how NMS which is listed on the OTC as NPTMY, is trading at US$9.74 at end of trade. At the beginning of Nov 06 it was US$1.89 and at the end of Nov 07 traded at US$10.04. Do the shares of NPTMY trade at 1 for 10 NMS ? Is there any way to interpret the rise and fall of NPTMY on the US market as against NMS here in Australia ?
