$5 a share is $5billion dollars.
For me, a stock needs a PE ratio of 10:1 to justify the price, or to be growing towards it. So..over the long-term, we'd need to be headed towards $500m yearly profit to justify that kind of price in my estimation.
I don't think those two things alone get us there. If they work well and we replicate and expand... maybe... but I think $5 is a little much.
That said, I do think we'll take off, and I hope you're right!
