I generally agree.
July 22: Earnings reported. Confirmation of GAAP profit will increase S&P 500 addition positioning starting in After Hours.
Sept 15: Battery Day. My expectation is that just as Tesla described the details of the FSD chip (HW3) on that day AND announced that it was already in cars produced weeks earlier, Tesla will continue to avoid Osbourning and whatever battery tech they announce will already be in cars produced weeks earlier.
S&P 500 Announcement. I'm expecting this in Sept. The S&P 500 Index Committee does a "reconstitution" typically every quarter, but they skipped March 2020 and then just did one last month (June).
CNBC Quadruple Witching. The next such event is scheduled to take effect after market close on Sept 18, 2020 (
S&P Calendar spreadsheet). I'm
guessing that the Committee might want to combine these two events into one, since both will have a large effect on the weightings of stocks in the index and they wouldn't want to have two such events close to one another.
Looking at
S&P search for "join S&P 500", there are about 5-6 actual (not business) days from official press release announcement until additions take effect. So, that makes a likely S&P announcement for inclusion of Tesla around Sept 12-13. Which is before Shareholder Meeting/Battery Day.
EDIT: Lessmog
pointed out that Shareholder Mtg/Battery Day is actually Sept 22. That changes my stock trading ideas, as S&P 500 inclusion and effect should be already baked in by then. Could be we get the rush on announcement for 5 days, then down after inclusion, and then up again on all the cool tech from Battery Day. Hmm.
