One thing to keep in mind for today's trading: the Model Y removed a major source of uncertainty
for the shorts.
If you think Tesla is a shorting opportunity then the Model Y unveil was a major source of wildcards for 2019: Elon could have announced much earlier Model Y production than expected, or could have made some other surprise announcement with a big effect on valuation and the stock price.
With the Model 3 SR and the Model Y unveil out of the way any shorts sitting on the sidelines might feel strengthened in their short thesis, and the false narratives out today from the usual suspects are egging on that thesis. So I suspect there's a lot of shorts who shorted today with a cry of "the Model Y won't save them from bankwuptcy!!!".
I think as a result today's short volume might be showing a big uptick in short percentage, after relatively low levels in the past couple of days. Short-term longs speculating on a Model Y unveil surprise might be unloading, while there might be increasing institutional buying, although they might be waiting to see how big of a momentum the shorts have.
But if you are bullish about Tesla like
Ron Baron:
and if you agree with him that TSLA is undervalued and you are ready to wait, it's a good moment to take their discount, or wait and see how far they are able to drive down the stock price.
If you think that Q1 is going to be awful, with another round of FUD, then you might want to wait for that event as well, whose magnitude will probably be narrowed down in about 2 weeks when the Q1 production and delivery numbers will be announced on April 1-2.
