The Canadian cannabis market- past, present and future

The past, present and future of Canadian cannabis companies.

Not all cannabis ETFs perform equally well given their different constituents and below is the performance of each in September ranked from the best (-2.5%) to the worst (-18.5%).

So far in September, the 19 pure play non-penny marijuana stocks are up 10.5% compared to just a 2.3% return for the 313 pot stock universe strongly suggesting that the resurgence came almost exclusively from the larger cap stocks in this sector.
