The price in all markets drive on some sort of speculation. Why else would we see price fluctuations?
This company's value already surpasses the $1 billion dollar mark in my book for being part of an industry that already makes billions per year underground. It also happens to be (what I believe) the only company in the stock market that has real MJ products and multiple subsidiaries with wheels spinning in the MJ industry.
I'd pay $1 per share of MJNA today. Who knows what it'll be valued when this becomes a nationally legalized industry.... PPS will probably surpass $10, especially with expansion.
