All are risky as government regulations could change and revenue is basically non-existent for many with taxes and potential capital expenditure eating into any gains over the coming year or two.

My matrix is based on offering price + 75-100% gains in terms of possible low retraces, this is significant for some companies sitting 200% higher than listing but for others such as MMJ has proven to be true.
