Summary
Fuyuko, a money YouTuber with $6 million in assets, compares the S&P 500 and the All Country World Index (ACWI) as core index investments. Both funds offer strong long-term growth and low fees, but differ in focus: S&P 500 concentrates on 500 US companies, while ACWI diversifies across 47 countries with about 3,000 stocks. Although the S&P 500 has slightly higher returns, ACWI provides better risk diversification and automatic portfolio rebalancing. Fuyuko chooses ACWI to hedge against uncertain future growth in any single country, valuing peace of mind and global coverage. Despite ACWI’s lower recent returns and exposure to emerging market risks, its broad diversification aligns with modern portfolio theory. She recommends index investing as a simple, effective strategy, especially for those less interested in active stock picking, and uses ACWI as a stable core while exploring satellite investments. This approach balances growth potential with risk management in a changing global economy.
