I bought all 3 around the same time VXUS and VXF haven’t really been making much gains for me and I know it’s a strategy to pair these ETFs together but why not just put it all on VOO? VXUS and VXF only grew around 25% over 5 years while VOO grew 75% what’s the rationale behind owning all 3 when VOO has substantially more growth?
