> been thinking about pulling my money from all of the US funds that I currently have

What’s holding you back? And what alternative investments are you considering?

I recently did homework to decide whether to double down on VOO (S&P 500 index) or to diversify via VXUS (ex-US index), and concluded VOO is better for my risk-adjusted ROI outlook and time horizon.

Same. Though I’m 85%+ VOOG

Momentum, really. I usually just buy more of a given fund and don't really take any out. My small portfolio is split across different funds, so I'd probably just split around the money I'd withdraw from the US-based ones into the other ones.
