with regard to the role of naked shorting going into a stock split, there was a dedicated thread about this as early as 2013:
The Rolling Naked Tesla Short
Thank you for finding this thread from 2013 created by notable TMC contributor
@luvb2b it's an amazing backgrounder to the current discussion, and comes more from a insider's technical understanding of the MMs short selling exemption for Option hedging.
He points the finger at likely a large MM conspiring with a hedge fund for options purchases causing the near instantaneous naked short sales sometimes amounting to up to 2% of TSLA entire outstanding shares (not just the float).
The best part of the thread IMHO is how he explains the mechanism for perpetuating a naked short position thereby avoiding paying carrying charges for share borrowing (
@Boomer19 this explains why TSLA borrow rates are low; this scheme doesn't depend on borrowing shares conventionally thus does not drive up the cost of borrowing shares), all the while never intending to deliver actual shares associated with these outsized naked short sales.
@luvb2b comments that this is likely an illegal scheme.
Paging
@StealthP3D @FrankSG @Hock1 I think we finally have stumbled upon our viable mechanism for naked shorting, and by extention, how this scheme is disrupted by inducing other MMs to call in their short shares in advance of a Share Dividend dispersment.
This scheme depends upon the hedge fund purchasing Options, which then induces the MM immediately to sell large numbers of TSLA shares due to their delta-hedging requirements. The hedge fund thus able to employ naked short selling by MMs to sell massive numbers of shares w/o locating them first, or paying the fees associated with borrowing shares to sell short. The other advantages are speed and the ability to sell arbitary numbers of shares without the normally expected restricts of supply, demand, and cost elastisity of borrowing those shares. Or as
@Unpilot would say, "
bastages".
This is the
ACTUAL MECHANISM by which this scheme is able to crater the SP: They can short sell an arbitary number of shares, indeed however many shares are needed, to burn through the order book and thus force the SP to their desired price, thus making these shorts almost instaltly profitable. That's what we saw with the huge SP plunges on Feb 4, 2020 and again on July 13, 2020.
I believe this is also what we saw on Fri, Aug 21, 2020 from 3:32 to 3:36 pm where dumping 573K shares dropped the SP from $2,079.89 to $2,049.05 in 5 minutes. And magically, Call Writers (mostly MMs) saved about $28M in payouts to holders of those $2,050 Strike Call contracts (just ask for details if ur curious).
And the 2nd best part of the 2013 thread by
@luvb2b ? Almost nobody else has ever read it.
So here's a link which will take you back to the discussion in Apr 2013. Note that
@luvb2b has not been active on TMC for over 29 weeks, according to his profile so we will likely be best served by continuing this discussion here in Main rather than on the old thread:
if my theory is correct, the behavior is illegal. this trader is effectively shorting with no intent of ever delivering shares. the market maker helping him also would be running afoul of sec rules.
