What this means for investors
Both funds offer international stock exposure, but IEMG check a few key boxes for investors. It provides a lower expense ratio, higher dividend yield, and better recent returns. This may appeal to investors who want to boost their dividend income.
While IEMG has more than doubled NZAC’s total return (including dividends) over the past year, NZAC has outperformed over the past five years. Since 2021, IEMG has returned 23%, trailing NZAC’s 57% return. That is quite significant and shows that NZAC may perform better across market cycles.
The difference in returns over the past five years highlights IEMG’s main weakness: it is dependent on emerging markets performing well. By comparison, NZAC’s trailing five-year return benefited from more exposure to U.S.-based tech stocks.
IEMG is better if you’re looking for a highly diversified international fund. However, NZAC may be better for an investor who wants to invest in climate-friendly companies while still gaining global exposure and growth.
