A rational valuation would require an earnings per share (EPS) of $.25 at a multiple of 20xEPS to get to $5/share. That would mean they'd have to turn a profit of about $67 million/year. That's about $5 or $6 million/month.
Will worldwide retail get us there with some combination of MCIG, VCIG and Vapolution - perhaps throwing in LiquCig. I think it's possible within a year or two. But then the market isn't always rational and will be looking ahead to profits in the next 6 to 12 months so it could happen sooner than we think.
