Oh, a note...
If Tesla has been building Model 3 battery modules for months now, they've been building them with Panasonic's 2170 output. I doubt the Gigafactory Model 3 cell production has been up and running for months. I expect that it won't ramp until July-August and that the first Gigafactory module is making TE product (NMC). Of course, they could make runs of NCA on it, but it would make sense to use Panasonic's production lines first.
We should start to consider what we would think is a success for Model 3 output in the months ahead, as well as what the market will perceive.
Personally I am more interested in the quality of early production models than the quantity although it may be difficult to get useful intel until non-employees start getting their cars. In terms of volume, market expectations still seem to be relatively low compared to Tesla's plans but it is difficult for me to predict market reactions.
Part of the challenge in predicting the market reaction is that while the Model 3 ramp is obviously critical context is important. There are a large number of potential market moving events on the horizon. How these play out could have a significant effect on how impatient/forgiving the market is for the Model 3 rollout.
Here is a list I jotted down recently for my own purposes:
Potential positive events:
June 2 factory VIP event
June 6 SH meeting
July 2/3 Q2 deliveries
M3 launch (July/August 2017)
Initial FSD differentiation (6-9/2017)
Aug. 2017 Q2 results
Semi launch (9/28/2017)
350+kw Supercharger (possibly 9-10/2017)
TE ramp (2H 2017)
4 new GF location announcements and updated long-term plans/goals
M3 initial ramp to 5000/month (12/2017)
FSD demo (12/2017)
M3 initial margins (mid-late 2018)
TE margins (mid-late 2018, possibly later)
FSD functional with human oversight in some real-world settings such as delivery of goods from warehouse to warehouse near freeways (mid-late 2018)
Initial Solar Roof ramp (late 2018 or 2019)
wild cards include analyst upgrades, new "brand name" investors, new products, EV/solar/storage mandates or regulatory changes, etc., solar roof order info/ramp, Semi reservation info/Model 3 updated reservation info
Potential negative bumps:
Problematic M3 launch (timing or quality)
Problematic M3 ramp (ditto)
4 new GF location announcements and updated plans/goals (if cap needs perceived negatively)
FSD demo delays (needs to be major to matter)
FSD competition proven to be tracking ahead of Tesla
AP2/FSD serious injury accidents
Semi is a flop (unlikely)
Excessive cash burn/cap raises
Wild cards include macros, personnel/union issues, macros, tax law and other regulatory changes esp in US or China, macros, unknown product defects, macros, bullish analyst downgrades, macros, more effective FUD.
