Valuation guru Aswath Damodaran revisits Tesla Inc. for his annual update on the company. He reviews recent news on the name, and considers what would need to happen for Tesla to become a viable car manufacturer. Finally, he moves on to valuing the company. One of his scenario's, a "plausible, not probable" scenario, has Tesla at $400 / share. However, Prof Damodaran thinks the more probable value is quite a bit lower than $400, or yesterday's close for that matter.
