The sharemarket in the long term always reflect the value of the company. I bought oregon minerals which were taken over by oilsearch at $1.05 per share a few years ago. I saw them painfully go down to 60c only to enjoy them going up to $3.50.
People hated PNG companies a couple of years ago - but they love OSH.
Only thing I am concerned with is the CGT when I sell them in the future.
