At around 3:20, seeing the lack of shares, the big index accumulator started flooding the TSLA market with sell requests, overwhelming demand & triggering stop losses of retail & other investors.
The sell tick below alone was over 400,000 TSLA shares.
The index accumulator picked up millions of shares from the artificially triggered stop cascade, then started buying aggressively at 3:50, when the lack of index shares became obvious to other market participants too.
In the closing cross, the index accumulator provided just enough shares (69m) to avoid a higher than $700 close: $695.
Then in after-hours ~45m shares were distributed to the index customers, in large block trades, at a $15 discount, to lower the indexing rebalancing cost.
If about 10m shares were accumulated anomalously in the disorderly artificial stop cascade the largest buyer (who had early insider information about the shortfall of indexing shares) caused about 10m shares to be sold at an average price of $635.
If these 10m shares, bought artificially low, were sold to indexers at a weighed average price of $690, then the damage to affected Tesla shareholders was ($690-$635)×10m = $550m.
Anyway, the more important question for next week is that despite the stop-cascade shenanigans, only 69m+45m = 114m TSLA shares were passed to indexers, indicating a potential 10-15m shares shortfall.
If true, then index funds will still have to buy TSLA shares in the next 3 days, to finish the S&P 500 rebalancing. The extra $600m+ in lower-price shares might be the funding for this.
Depending on macro conditions, this might set next week's TSLA price action.

I.e. only about 69m shares worth of shareholders were willing to sell to index funds in the closing cross, and a large short seller sold them ~40m shares after-hours for $695.
This explains the sharp AH "spikes" to $695 visible in charts that many commented on.
Here's a finer grained view of the market anomaly: lots of huge orders with hundreds of thousands of shares slipping up to 695 & filling there.
I presume these were the indexers buying OTC/dark, while the entity 'painting' the price moved liquidity back to $680 quickly.
🟢 Bullish scenario: if there's a significant index buying shortfall as the numbers below suggest, then a post-inclusion rally might begin on Monday.
🔴 Bearish scenario: if that's wrong then @garyblack00's 10-20% pullback is possible too.
Any short term hedge funds driving a 10-20% correction had:
✅ 47m buy liquidity in AH to sell @ ~$680
✅ 69m liquidity to sell @ $695 on the close
Why didn't they sell? 🤔

There's two main explanations:
✅ either hedge funds are confident about higher TSLA prices next week
✅ or the HF-selloff hypothesis was false to begin with, as explained by former large hedge fund quantitative equities and derivatives trader below.
In reality probably quite a few of the buyers on the close were not passive index funds:
❌ shorts covering or getting covered
❌ active funds that didn't want to stay TSLA-short against their benchmark & wanted to track TSLA at exactly the closing price
❌ options writers

So the 13.6m shortfall of indexing shares is likely substantially higher.
Monday TSLA trading will IMO be determined by market participants thinking these through, and by continued index fund accumulation.
But macro might interfere, and so might market shenanigans. 🤠
I expect next Monday to be crazy: passive index funds only managed to buy ~70m out of the ~130m TSLA shares required, despite paying an all-time-high $695 price for 70m shares (!).
They'll still have to accumulate another 50m shares. (!)
Assuming I understood the market mechanics outlined by @TeslaPodcast in yesterday's video correctly, that almost all index funds would buy on the close, the minimize tracking errors.
BTW., @SEC_Enforcement should urgently look into the shameful market manipulation that occurred shortly before the closing cross: when big market participants pushed the price down below $630, to trigger stops and to use delta hedging to provide them shares...
While it's technically true that index funds could have started buying TSLA on Wednesday already, they didn't, due to the big risk of "tracking errors".
Index funds is judged by their tracking accuracy & by their management fees.

TSLA enters the S&P 500 out of the blue, at a huge 150 basis points weight worth $80b, 130m shares.
Yesterday index funds were still 150 bps away from their target allocation.
