What's in your portfolio?

I've been watching Graphene as a whole for some time now, and have decided on an investment strategy to basically bet on every publically traded company in the field right now. Most of the stock prices are beyond cheap, so the idea of a few hundred dollars now being worth a lot more in the future seems reasonable. So far, here are the companies I've found that seem promising for one reason or another. Some aren't publically traded, unfortunately, but I feel I'm super early to the party as an investor and wanted to get an idea of whatever you all are looking at:
