Foolish take
ETF investing can be a great way to gain exposure to broad or specific market trends without the effort and risk involved in picking individual stocks. SPGM is a low-cost broad-market ETF that covers nearly the entire investable universe, across large-, mid-, and small-cap companies in both developed and emerging markets.
NZAC is a much smaller, much more targeted investment in companies that meet an environmental benchmark. The fund is designed to exceed the minimum standards for a "Paris-Aligned Benchmark," holding companies that meet the criteria of the Paris Agreement to limit the increase in the global average temperature to well below 2 degrees Celsius above pre-industrial levels. NZAC is a great example of an ESG (environmental, social, and governance) investment, focusing not only on financial performance, but also societal impact.
Despite the massive size disparity, the funds have performed similarly over the last year, with SPGM returning 16.36% and NZAC returning 13.5%. That's due to the fact that the top holdings of both funds are the same three tech giants, which have been largely driving the market's performance for the past few years. The funds also offer similar dividend yields and low expense ratios.
Large ETFs that track the entire stock market, either in the U.S. or the world, are often good core holdings for the foundation of a portfolio. In this case, because SPGM also covers a range of market caps and market types, it naturally diversifies against risk. Investors interested in ESG principles, or who believe that practices that are good for the climate are also good for business, may want to look further into a more targeted ETF like NZAC.
