Well you have a choice. Either diversified portfolio and that includes international. Or some tilt to it that reflects your values.

Keep in mind if you had a pension or an annuity they would be doing the same thing so both have portfolios. Just one is more direct and you have more control.

It’s too late to sell now. If you want to move your investments elsewhere, you’ll need to wait until they climb back to all-time highs - which could take at least a year or so. That said, not investing in the U.S. at all would be considered a poor financial decision by most informed investors. You’d be leaving a lot of money on the table, and honestly, kidding yourself too if you think non-U.S. mega corporations are somehow more virtuous.
