Apologies, shorting-bans isn't necessarily a long-term view rule, just an example of something they could do around constraints on trading, not necessarily something they should do, just I expected some kind of trading rules to fix the real problem, which in my opinion is investor pressure, not management short-sightedness.

The rules I suggested aren't necessarily good rules, just random examples. That is, to me the most powerful driver for short term thinking isn't managerial in nature, it's investor in nature. That is, it's the short term fluctuations in market value as investor reactions to events or goals that have nothing to do with the company's bottom line or long term goals, etc. But if essentially random forces are affecting the value of your company, there will exist pressure on management to respond to that pressure. So to me the real fix is some set of rules constraining investor behavior with regards to how the stock is traded, not some nebulous honor-code among CEOs. I am not sure what the rules should be, I just picked random rules out of my butt. But I think there should be some trading constraints: if you truly want to incentivize long term vision, you have to remove the short term pressures.

Like your suggestion for a trading window every 5 years. I have no idea how well that would work, but it seems reasonable, and is the sort of thing I expected for the site, but they seem not to have anything like that in mind. Which to me means that have entirely missed the mark.
