I'm pretty sure people who caused this stock to jump into the 600s after last ER doesn't have reading comprehension problems. It's not a secret or a surprise if Q1 is a loss. It's in the letter and was talked about on the call many times.
Surprise now involves production ramp of Y and Shanghai 3 being SLOWER than the initial Model 3 ramp(what is priced in is faster than the OG Model 3 ramp),a massive loss which makes s&p inclusion for post q2 to be unlikely, massive tank of S/X sales, and delivery under 100k cars. But even if Tesla delievers under 100k cars, they can reinerate their 500k+ car delivery guide again and this time it will have credibility unlike last time.
The rest are already priced in.
