If you are new to this, my only bit of advice is to sell in increments on the way up to Nov 2nd. Odds are there will be a very large selloff if Prop 19 is approved. Buy the rumor, sell the news. After the selloff I will be reacquiring shares as I will be long in this company. The pharmaceutical capabilities of this company is huge.
On the other hand, this stock will tank if prop 19 is voted down. I will be holding a very small position going into the vote. Probably a fraction of my profits.
