I've been very confident and dead wrong before, although I doubt I'm alone in that...
However, I'm confident in this case due to management's long history in graphene R&D. Being 1st to market with graphene-enhanced filaments is a big deal to me- even if the market doesn't agree over the short term.
My shares are not for sale- I'm happy to hold because I believe there is great potential here for a JV with a major player or possibly a buyout.
