The one thing that would get me to sell some TSLA shares right now would be an opportunity to invest in SpaceX. I've investigated this possibility and I'm not finding any shares available for retail investors (even accredited investors). I'm already monitoring the SpaceX investor threads here on TMC. So, for now, I think we as Tesla investors need to be content with the knowledge that SpaceX and Tesla share technology to the benefit of all. SpaceX's success does spill over to Tesla, even if we can't invest directly.
If you have not invested in SpaceX, are there any practical/operational issues? I gather they have a private stock trading every quarter or at least annually to ensure the employees have a marketplace to sell their employee stock.
