We're gonna creep up to $695 for June 18th expiration, about where we were when blockbuster 1Q deliveries were announced. Now everyone will be doing backflips of joy just to get back there. Amazing work the MM's can do to reset the narrative and expectation. Perhaps that's actually part of their job.
For those who are unaware (or have simply forgotten), $695 was the closing TSLA share price just before the S&P 500 inclusion (Fri, Dec 18, 2020).
There are quarterly rebalancing events for the S&P 500 index, with the largest of those by trading volume on the 3rd Fridays of June and Dec.
Coming up in just two weeks, the 3rd Friday of June is an Options expiry day (also a so-called "triple-witching" Friday) as well as the rebalancing date. Options open interest for Jun 18 expiry is already over 1.16M contracts. This insures a large volume day, but also means that the SP will be strongly affected by the interests of Options stakeholders (both options writers and holders).
Note that during the March 2021 rebalancing period, TSLA had its highest ever single-day share price gain of $110 closing on Tue Mar 9 at $673.
Why the contrast in dates? Well, the way that S&P DJI currently does their quarterly rebalancing, the "investable weight factors" (IWF - basically an individual equity's portion of the entire Index) are frozen at the share price at the close on the Tuesday BEFORE the 2nd Friday of the rebalancing month (whew, what a mouthful).
I think this means that the $110 single-day gain in TSLA restored its rebalanced weight in the S&P 500 to almost exactly what it was initially set at in Dec 2020. The will be only the 2nd rebalancing event that I've followed closely, so still gathering data.
I think this also means that the closing share price on Tue, Jun 8, 2021 may be used to factor in the IWF for next Friday's rebalancing event. This (may or may not) affect the number of shares that large index funds buy or sell over the course of about +/- 5 days from the event (that may have started today).
Also, Dec 2020's event showed us that the large majority of the shares traded by index funds happend at the closing cross on the 3rd Friday (and A/hrs). Tue, Dec 8, 2020 saw a similar bump in TSLA to close at 649.88 (SP went down $45 the following day).
Anyway, wanted to give you all another data point, and I'll continue to report what I see. I do think this is an important factor given how large a component TSLA is in the S&P 500 and how volatile it is. Anything which drives genuine transfer of shares (not HFT by MMs/hedgies) will affect the SP (up or down), as we've seen.
Cheers!
