pot EFT is a good idea but I am not aware of any. But you may build your own buying couple of stocks in a basket. Singe stocks are very dangerous but a basket could be a safer option.
If you build your own basket, buy stocks which are fully SEC reporting.
If you are interested I could post a list of SEC reporting pot stocks.
No particular opinion about NVLX. The technology looks silly, but now they have money to run Ph 2, so a lot of time to have nice stock appreciation.
HZNP is on my watch list since $4. Waiting for a drop which never happened. Congrat for the excellent pick.
I used to have a large position in SYN. Now it is tiny position and it is on autopilot.
Check PGNX - bought some today. They completed a secondary today and may go up from here until the PDUFA in a couple of months.
