'- How is LTSE different? Seems like: Companies and investors “promise” to have a longer term focus via planning'
I don't think "promise" is the word. The fact the exchange says it's focused on long term, would incline companies that wanted to focus on long term to list themselves there. Likewise, it would incline customers to list themselves there. But what incentive is there for short term traders?
Right now, on the normal exchanges, you have both types. And the loudest voices in the room are the short term types. They're the ones paying the closest attention, attending the shareholder meetings, etc. The long term holders are far less engaged.
What does this have for those short term traders? Nothing. There's no reason to pile into this when all the incentives of the companies listing, and existing holders, are aligned to long term. If you're looking short term, why would you want this, knowing all the other players will be aligned to take hits in the short term, if it pays off long term?
Not saying that this will be successful, but I can see it working because of that. Not because it's more attractive to long term holders, but because it's less attractive to short term.
That said, agreed that some ways to enforce it would be nice. But those have some noticeable downsides too (i.e., if a company makes decisions you don't agree with, but you're locked into a hold position...).
That said, as was mentioned elsewhere, it sounds like voting power is tied to how long you've held, as well as number of shares. So that certainly helps silent the churn and burn voices.
