Given there is going to be serious economic disruption there is a lot be said for diversifying your assets. If most of your assets are currently in the US moving your pension fund into assets held outside it is a strong de-risking move, particularly if you can move it out of the country totally using a foreign prover provider as well as holding non-US assets(not sure if that last is legally possible, don't know much about your pension system).

Note you may get poorer performance - it's really up in the air just yet what the short term impacts will be economically (depends what King Mango ends up deciding, it's mostly speculation right now)

Canadian. I've divested 100% of my meagre savings out of us stocks. USA is not a reliable trading partner, or a leader in anything anymore except deceit.

That does literally nothing though. Buying a share of a company is like buying a used product, none of that money goes to the company. The only benefit to a company is the share price rising, and your contribution to that is effectively zero, and it only matters if the company issues or buys back shares, which is somewhat rare.

It's the same reason that buying "green" shares does nothing.

Invest based on what's most likely to give you a good return, even if you don't agree with their products. And then buy products based on your convictions. If you want to feel like you're "sticking it to the man," use the profits to buy from their competitors.
