So, I was being sarcastic.
...
I’m not expecting quite the same degree of violent reaction with the next split, though, the same conditions exist.
Sarcasm ; sometimes the only rational recourse when thinking of share price fluctuations. Most of the rationalists ignore human emotional reactions, and for them there are all the myriad quantitive approaches which as our esteemed moderator
@AudubonB points out implicitly, they substitute precision for accuracy. In my opinion the best hint of that practice is making a forecast that goes far beyond the last significant digit.
So, to splits. In the world of partial share purchases and sales round numbers for shareholders transactions are just a convention, with a tiny bit of transactional efficiency sometimes. Thus the value of a split is mostly psychological, and the advantage of Never Split is also psychological. Most aficionados of the psychology of markets use multiple share classes to have it both ways. Hence the prototype of it all, BRK. BRK-A $522,900 as I write this. BDR US$=16.86. The latter is the Brazilian Depositary Receipt. Of course there is no doubt that these are not the proverbial apple to apple comparison.
Back to TSLA. Since they quite obviously have zero need for new capital a split or a new class of shares would have no purely rational quantitative function.
As all of us who pay attention probably know Tesla gains huge positive benefit from, mostly, the retail investors. They (we) publicize and promote incessantly, enthusiastically and relentlessly. A split, say, 10:1 will act to broaden our base and encourage positive feedback from the Robinhood crowd as well as the more traditional Schwab and Fidelity smaller investors.
Such a split will mean essentially nothing to those of us who date our first TSLA shares almost anywhere in the previous decade. It will end out yielding a higher net price simply because it will broaden the base of investors. As a not-coincidental consequence quite a few institutional investors understand that 'irrational' effect, so they too will stock up on TSLA to some degree.
Those of us with really long memories will remember that once upon a time US share transaction fees were higher for small numbers of shares ("odd lots") and cheaper with lots of 100 shares. Higher share volumes and discounts of various types and colors, including "soft money" (don't ask, it no longer exists). Thus splits had, back then, the effect of reducing transaction costs for smaller monetary transactions, so had a purely logical rational role. The inverse also was true, 'penny stocks' would sometimes happen when overly aggressive splitters fell on hard times, and transactions cost went up again.
So rather than debating 'logic' just understand that a split for TSLA is a superb example of how Tesla does marketing. They are so very good at it that they have no need for advertising. Nobody is so skilled as are they at marketing in cyberspace.
Understanding how Tesla does marketing also explains why the Twitter affair is relevant to TSLA. Frankly, it matters little whether Elon takes control or does not. His popularity in the prospect base for the next generation of purchasers continues to rise. The split just accelerates the narrative.
The problem, as we all know, is increasing production as rapidly as possible. A split helps retail waiters to keep waiting (im)patiently.
