Unless one means hedge in the traditional sense
Because CannaVests shares are so illiquid, a possible use for the certificates would be to pile them along a property line, although I guess that would create more of a low wall than a hedge.
Regarding Cannavest, I have to wonder how many shares are actually in the trading float.
I know what the filings say (8.9M or so,) but based on the lack of trading, even on news, I think that there are only a few thousand actually in the market.
Really low volume with MJNA so far today, with less than 600K shares traded as I write this.
