Assuming Q4 is nearly as good as many of us expect, I think a credit rating upgrade could happen. Rating changes are lagging indicators and subject to momentum. Cash flow should be amazing, even with 3 plants being built. Wall Street is being put on notice with S&P inclusion and Q4 should be the final wake up call. Cash on hand over 15 billion, operating income over 1 billion and on track for 2 billion by Q4 2021. Tesla will probably only project 800,000 car production in 2021, but barring another 2020 cluster of a year, should be closer to 1 million, with over 55 billion in revenue and a path for similar growth in 2022. TSLA may fall after S&P inclusion is done, but Tesla fundamentals will drive the stock again in 2021.
At some point in 2021, they will announce a new compact car, below the Model 3. Normal Elon style would be to do that in Q1, after Shanghai Model Y production is running, but I think they want more time to get the Y production higher, and to possibly update the S&X platform. The addition of a higher volume compact $25,000 or less car, with a late 2022 production target will give Tesla a path to nearly 100% growth in 2021, 2022 and 2023.
Interesting issue with a rating upgrade, many funds won't buy Tesla now, since it is junk status. An upgrade to investment grade, should add demand for TSLA stock again. Pension funds and other long term investors are blocked from the stock today, so an added ~10% of the float could be soaked up next year.
