A complete withdrawal to influence US legislation carries significant financial risk and uncertain political impact. The US market is vast, and the impact of even a large outflow might be limited. Every international investor should prioritize financial stability over political influence.
There are better ways for investors to approach, like
Engage U.S. policymakers diplomatically and advocate their concerns.
Invest in value-aligned firms to influence corporate policy.
Collaborate with other international investors to amplify voice and concerns.
I guess the more strategic approach will always benefit.
