Large institutions have been moving in this direction for about a year.
I just put together a fairly more stable and diversified portfolio that is effectively only about 15% in the US. It involves some short-term private equity, lots of commodities, European cyclicals and financials, some small Deep value, energy and climate change infrastructure is on solid ground and being well funded around most of the world… they really are plenty of bright spots and lots of good advice out there, even from public letters from places like Van Eck, Piko, GMO funds, and others.
There are a number of very important categories to avoid, like convertibles, but overall it’s quite possible if you have a little bit of acumen with investing.
