What to look out for
Diversification versus concentration: IWDA spreads across 23 developed countries, CSPX focuses on the 500 largest US companies, at a lower cost (0.07% vs 0.20%). Note that the US already weighs over 65% inside IWDA, so the two overlap substantially.
Historically the S&P 500 has outperformed, but nothing guarantees it will continue; MSCI World spreads the bet across more economies. See our geographic allocation article.
