I don't think a 10b5-1 sales plan filed months in advance can be so picky. More likely, Elon has final say on the 'go/no-go' for each sale, but that likely just means veto'ing planned sale days (if that even happened).
Now, it seems just as likely that Elon is completing his share sales through dark pools, which implies no more sales on the Open Market. Here's Elon's tweet from just a few hours agoL
I think he took Gary Black's advice and did some research on the best way for an Insider/Founder to sell shares in bulk: locate and sell to a few willing large buyers (Scottish Baillie Gifford & Co. or the Norwegian Public Pension fund, to name but two). Any one of which understands where TSLA is going over the next 2 years, it's a literal feast for a whale.
That handles all the 900K share sale days, which were clearly done to pay the taxes incurred by executing his 2012 CEO stock options. I think the 'missing' days of sales are now complete too, just done through dark pools (privately arranged sales).
The one outlier in this is Elon's 2nd day of selling, which was the largest volume day, and not concurrent with the exercising of any stock options. I think now, based on information out in the past 24hrs, it's quite possible Elon was seeking some 'pocket money' just in case he needs to recapitalize SpaceX and the Raptor + Starlink terminal production lines in 2023 (if revenue milestones are not met on time).
If that latter consideration did in fact motivate Elon's extra sales, then I think that also is a further indication that Tesla will NOT be buying either SpaceX or Starlink in the future. Does not rule out an IPO for Starlink, but I recall Elon saying he wanted to wait until their revenue stream was consistent and predictable, which resolves down to (surprise!) Raptors and Starlink terminals
Cheers!
