I feel that's its overseas buyers for whom this type of share appears cheap. $30 on the NZX is a major but its a pretty small fish internationally. Combine that with the perceived potential and I guess it looks attractive.
I believe in the story wholeheartedly but I have plenty at stake without committing more.
I do wonder if the benefit of buying is diminishing however. At $1 with the potential to become $100 it is a compelling story but at $30 with the same potential....not so sure.
