Commenter argues VWRP's ~60% US stock weighting makes it a poor diversifier for a portfolio already 67% US, suggesting international or uncorrelated assets instead.
Unpriced research observations (excluded from Calls and Returns):
VWRP — AVOID The author argues VWRP is not a meaningful diversifier for a portfolio already 67% invested in US equities because the fund itself holds over 60% US stocks. Using it would duplicate US exposure rather than add international or uncorrelated assets. The author instead suggests allocating the remaining 33% to international stocks or uncorrelated assets such as bonds or gold. resolved_asset_type_mismatch
An all world fund like VWRP is over 60% US stocks already, so you aren't really getting meaningful diversification your current set up.
