Choosing between iShares Core MSCI Total International Stock ETF (IXUS +0.05%) and State Street SPDR MSCI ACWI Climate Paris Aligned ETF (NZAC +0.32%) involves weighing broad international exposure against a climate-conscious, tech-heavy global strategy.
While both funds offer international equity exposure, they serve different roles in a diversified portfolio. The iShares ETF targets non-U.S. stocks across both developed and emerging markets, providing massive geographical diversification. In contrast, the State Street fund is a global vehicle that includes U.S. positions but filters them through an environmental screen to align with the Paris Agreement.
