I’m not sure how this works practically. Let’s say Apple wants to do this, and they list. Do they issue new shares of stock, and that dilutes their other shares?

If there are no restrictions on trading, and Execs get stock on LTSE, Wouldnt market reactions to quarterly reports still move price around, incentivizing short term results?
