A friend and I were trying to find out why this stock price went up. What we learned is that Graphite One and G6 Materails share a very simlair OTC ticker.
Graphite One OTC ticker is GPHOF and G6 Materails is GPHBF. Graphite One also had major news dropped about the company being a "High-Priority Infrastructure Project".
