By far, the majority of foreign equities trading in the U.S markets trade in the unlisted or otc market. Although I do not follow this particular security, and don't know whether it trades as an ADR, or ordinaries, my hunch is that its shares are unsponsored. Additionally, before a foreign company may apply for listing on a national market in the U.S., there are a number of certain minimum capitalization criteria which must be met. Finally, not all corporations even desire to be listed to begin with. GLTU.
