It's not a dumb question. The question is due to the wording from Tesla: "Each stockholder of record on August 21, 2020 will receive a dividend of four additional shares of common stock for each then-held share, to be distributed after close of trading on August 28, 2020."
Hence, the question is regarding what happens to shares traded from Aug 24-28. Thus far, I haven't seen a very good answer to this other than insisting that nothing happens. If that is the case, why is Aug 21 even mentioned? Why not just have Aug 28 be both the "stockholder of record" date as well as the distribution date?
Exactly this, thank you for stating it clearly.
