LOL your math is off by a factor of 100, they would be a 700 Million not billion dollar company at a dollar which is not all that crazy. Much less crazy for MJNA who currently has a 30 P/E and would have about an 85 P/E if their market cap was 700MM. For 1,100% revenue growth with 60% profit margin that's not too bad.
Hard to say for sure. But once the momentum kicks in, it will move. Look at the chart and notice large spikes in the past. Right now CBIS is a big laggard to MJNA and will probably do some caching up.
I red earlier that CNBC estimates the Marijuana industry is a $40 Billion dollar a year business, which is slightly less than Americans spend on their pets. However some estimates say that it's over $120 Billion a year, making it larger potentially than the Beer market.
Who knows, but recent price movement in these stocks could mean they are just getting noticed.
