An analysis by The Motley Fool compares Vanguard FTSE Developed Markets ETF (VEA) and State Street SPDR MSCI ACWI Climate Paris Aligned ETF (NZAC), noting VEA offers broad, low-cost international diversification with a 0.03% expense ratio and no U.S. exposure. In contrast, NZAC provides climate-focused exposure with a 0.12% expense ratio, but its portfolio is heavily tilted towards U.S. megacap technology stocks like Apple and Nvidia, despite being a global fund. The analysis suggests VEA is better for investors seeking broad international diversification at the lowest cost, while NZAC suits those prioritizing climate alignment despite its higher cost and tech concentration.
