Been holding this stock since mid 2018 so I'm currently in the red but see it as a reasonable chance of long term positive.
However I received an email today from IG Trading, my (soon to be former) online broker, informing me that they will no longer trade in stocks that have any exposure to the recreational cannabis industry. I have till May 24th to sell my shares or they will sell them for me. They will also not transfer them to another broker!! As well as CPH shares I have shares in another company in which I have also taken part in a share offer that currently has more of my money tied up as they've been in suspension since about 6 months ago. They are waiting for relisting and have just issued their 14th prospectus so who knows when they will be trading. Looks like those shares will be dumped as soon as trading recomences.
Pretty pi-sed off!!
