I think in practice this means that no one will use this exchange...
> Operating principles: In an earlier SEC filing, LTSE said that its corporate governance rules might include: increased voting rights for shareholders who hold company stock for long periods of time, restrictions on offering short-term incentives to executives, disclosure of impact of any stock buybacks, and requiring companies to have a board-level long-term product and strategy committee.
Presumably that could mean requirements on board memberships, dividend levels, types of employment perhaps? I find it a bit hard to see what stipulations they would have that aren't just good governance.
I think most of the approaches you mentioned wouldn't hold up for a large stock exchange because some off-platform trading site would spring up to fill the gaps. For example, you have a minimum holding period, but off-platform you can "sell" your shares at the current market price, then transfer them for free once the holding period ends. Or something.
I think you have to change the way the shares themselves work somehow (or how dividends work, etc). I'm not sure, seems like a hard problem.
