I just looked up the prospectus. 1 billion shares outstanding. 1 ADS = 1 ordinary share. That means the market cap at today's close is 12 billion USD, with options (diluted) probably even more.
They are just starting to deliver cars, all right, so the revenue will grow. But in H1.Jun18 they had revenues of 7M and cost of sales of 30M. And overhead of 480M. All figures in USD. That overhead figure doesn't seem to be an aberration as for full year 2017 it was 750M.
I confess I haven't looked deeper into the prospectus... but just from those numbers I am scratching my head
American investors who are far removed from the company threw 1b USD at this IPO. (160M ADS at 6 dollars). The smart money over at Robinhood is piling in now.
Guys (and girls), the markets are getting bubbly.
