I stumbled across more evidence that "magesterial inactivity" https://gunnarmiller.substack.com/p/magisterial-inactivity appears to work a lot better than conventional wisdom would assume https://www.ft.com/content/651cc7a4-27e3-4026-9381-76421a0203bb "How many assets do you really need in your long-term portfolio? In principle, you do not really need more than two: a global equity fund and a broad bond fund in your own currency, with the relative amounts a function of your return needs, ability to withstand short-term drawdowns, and need to control long-term risk on your ultimate portfolio. This gives you very good diversification, clarity and simplicity on what you are holding, and high liquidity with minimum costs if held through passive funds, mutual or exchange traded (ETFs). One could argue that your bond fund should be global, but that would add foreign-currency risk that is generally not well compensated. If you then have strong views on what asset types, countries, or sectors to have more of than is in these broad funds — say you fancy Technology — you can simply add a Tech ETF to these two funds. It is harder when there are certain assets you want to have less of, or not have at all — say oil companies. You would need a fund that excludes oil companies, but that may not exist if there are not enough investors like you who do not want to hold oil. If such a fund does not exist, then you will have to build a portfolio bottom up by trying to buy all the other sectors, for which funds will surely not all be available. Hence, it is much easier to execute overweights than underweights in a simple portfolio. In short, you will do quite well with holding only two funds: a global equity one and a local bond one."

This also says something interesting about commodities: "Nearly everyone should just buy a cheap global equities fund for diversification and a locally denominated corporate bond fund to minimise FX volatility, he says. Government bonds are only useful for managing drawdown requirements, so they have no place in your long-term strategy. Commodities don’t generate income so it’s probably not worth bothering with them either, unless you have strong feelings about extreme climate change or have some specific risk to hedge."
