Should be titled, "Waiting for Tesla to make a profit"...Market valuations don't always make sense.
With earnings (OK, really, losses) of -4.78/share, this stock price doesn't make a lot of sense.
Schwab has much higher margin requirements for buying TSLA than any normal stock.
Because this price is mostly speculation.
And the brokers know it.
I remember when the press was full of "3D printing is the future!" Headlines...and SSYS was bid up to $100.
At least Stratasys had earnings.
