A couple years ago when Colorado legalized it I made a list of openly traded companies, thinking it'd be a huge investment opportunity. I was too risk-averse to jump in, but I found my list of potential stocks and their prices about a year later. Of the dozen or so stocks, about half were delisted, one or two were at about 80% of what they'd been then, and the rest were on life support. Anecdotally, I took it as a good thing I'd stayed out. Really, each of these companies I had very little information about other than that they were "doing that new thing everyone's excited about". So... if you're going to invest, make sure you know the company you invest in and aren't just following the advice of a puff piece courting your cash.
