A question I've seen come up a few times over the past few weeks, including here on TMC, is how will the upcoming index funds required holding of TSLA on an ongoing basis impact TSLA's price from a supply and demand perspective.
If we could isolate the increase in TSLA's share price due strictly to index buying in this period we are entering, will the indexes effectively pulling these shares off the market (as long as TSLA is in the S&P) equate to a decrease in supply that supports an underlying boost in the share price that will remain regardless of the other events that will move the stock price over time.
I think the answer to this question is yes and no, because we can theoretically think of, at the extremes, two markets for TSLA shares.
The first theoretical market is the one the indexes are the most extreme example of (along with Elon Musk). In this market, TSLA shares are a one-of-a-kind item for which there is not a substitute. These indexes will have to hold about 1.5% of their assets in TSLA. They can't own "the next Tesla," or an ETF of EV companies instead. For these index fund's, it's got to be TSLA. For Elon, and any theoretical '100% cultists' or '100% TSLA HODL buyers' it's the same. TSLA is strictly a market of TSLA, and 15% of TSLA stock being taken off the market is a 15% reduction in supply for the item they are in the market for.
The second theoretical market for TSLA, at the extreme, is those for whom TSLA is a commodity. For the investment/trading, portion of funds available to them, all their investment/trading options are basically commodity items. Whether using TA exclusively, or a mechanical, financial metric only valuation process, etc, they chose a stock w/out any attention to the people or business behind the ticker symbols. For this group, the S&P pulling 15% of TSLA off the market, is not removing 15% of the supply of the item they are in the market for... it's an infinitesimal reduction in the supply of the far larger commodity of all investment/trading options they have.
Of course, in reality, there's only one market for TSLA shares. Most people are probably a mix of the two theoretical extremes of viewing TSLA's market. There actually are TSLA shareholders who basically are in that first theoretical market, but, they are probably a small minority of TSLA shareholders (even if that's not the case on this thread), though about to grow by the index funds being forced into that group.
So, as I see it, yes, supply/demand is going to impact the TSLA price by the index buying, but, not to anything like the extent it would if the whole universe of potential TSLA buyers saw TSLA exclusively as the entire market of a one-of-a-kind, irreplaceable offering.
