Investors seeking international diversification for their portfolios often consider Exchange Traded Funds (ETFs) for their broad exposure and cost-effectiveness. Among offerings from State Street SPDR Portfolio, two distinct options emerge: the State Street SPDR Portfolio MSCI Global Stock Market ETF (NYSEMKT:SPGM) and the State Street SPDR Portfolio Developed World ex-US ETF (NYSEMKT:SPDW). Each fund provides unique geographic and market capitalization exposure, catering to different investor objectives. Understanding their compositions and historical performance is crucial for making an informed investment decision.
Diversifying beyond domestic markets helps mitigate country-specific risks, such as economic downturns or political instability. Both SPGM and SPDW aim to provide this international exposure, but they do so through different lenses. SPGM offers a comprehensive ‘all-world’ equity solution, encompassing both developed and emerging markets, including a significant allocation to U.S. stocks. In contrast, SPDW is specifically designed for investors seeking pure exposure to developed markets outside the United States, acting as a complementary building block for a U.S.-centric portfolio.
Snapshot: Cost & Size
Comparing the structural aspects of these ETFs reveals important distinctions:
| Metric | SPDW | SPGM |
|---|---|---|
| Issuer | SPDR | SPDR |
| Share price | $49.45 (as of 2026-07-23) | $84.27 (as of 2026-07-23) |
| Expense ratio | 0.03% | 0.09% |
| 1-yr return (as of 2026-07-23) | 22.80% | 20.80% |
| Dividend yield | 3.10% | 1.80% |
| Beta | 0.84 | 0.92 |
| AUM | $40.0B | $1.7B |
Beta measures price volatility relative to the S&P 500; beta is calculated from monthly returns over the available fund history (up to five years). The 1-yr return represents total return over the trailing 12 months. Dividend yield is the trailing-12-month distribution yield.
The expense ratio, a critical factor for long-term investment, clearly favors SPDW at 0.03%, significantly lower than SPGM’s 0.09%. Lower expense ratios mean more of an investor’s money stays invested and compounds over time. Additionally, SPDW offers a higher dividend yield of 3.10% versus SPGM’s 1.80%, which could appeal to income-focused investors. However, SPGM boasts a considerably larger Asset Under Management (AUM) at $40.0 billion compared to SPDW’s $1.7 billion, indicating greater liquidity and institutional interest for SPGM, though both are sufficiently liquid for most retail investors.
Performance & Risk Comparison
Examining risk-adjusted returns and volatility is essential for global ETFs:
| Metric | SPDW | SPGM |
|---|---|---|
| Max drawdown (5 yr) | (30.20%) | (25.90%) |
| Growth of $1,000 over 5 years (total return) | $1,572 | $1,675 |
Over the past five years, SPGM has demonstrated a lower maximum drawdown, indicating less sensitivity to market declines than SPDW. This could be attributed to its broader diversification, including U.S. equities, which often exhibit different performance characteristics than purely ex-U.S. markets. Consequently, SPGM delivered a higher growth of $1,000 over five years ($1,675) compared to SPDW ($1,572), suggesting better long-term performance and potentially lower overall portfolio volatility when combined with other assets. SPGM’s beta of 0.92 signifies it tracks the broader market (S&P 500) closely but with slightly less volatility, whereas SPDW’s beta of 0.84 indicates even lower correlation and volatility relative to the S&P 500, aligning with its role as a diversifier against U.S. market concentration.
What’s Inside
State Street SPDR Portfolio MSCI Global Stock Market ETF (SPGM) aims to replicate the performance of the MSCI ACWI IMI Index. This index is designed to represent the full opportunity set of large, mid, and small-cap segments across 23 developed and 24 emerging markets. SPGM holds a vast portfolio of 2,927 stocks, offering extensive global diversification. Its sector allocation is heavily weighted towards technology at 31.00%, followed by financial services at 16.00% and industrials at 13.00%. The fund’s largest positions reflect this technological tilt, including Nvidia Corp (NASDAQ:NVDA) at 4.33%, Apple Inc (NASDAQ:AAPL) at 4.17%, and Microsoft Corp (NASDAQ:MSFT) at 2.40%. Launched in 2012, SPGM has paid $1.54 per share over the trailing 12 months, resulting in a 1.80% dividend yield at its recent $84.27 share price. It’s important to note that despite its ‘global’ label, 61% of SPGM’s total holdings are in U.S.-based stocks, making it less of a pure international play and more of a total global market solution with a significant domestic lean. Outside the U.S., its primary exposures are Japan (5%), the United Kingdom (3%), and Taiwan (3%).
State Street SPDR Portfolio Developed World ex-US ETF (SPDW), on the other hand, tracks the S&P Developed Ex-U.S. BMI Index. This index specifically covers developed markets excluding the United States, providing a more focused international allocation. SPDW manages 2,439 holdings, concentrating its exposure outside of the U.S. The fund exhibits a significant allocation to cash and equivalents (32.00%), which can impact its overall equity exposure and may reflect tactical decisions or regulatory requirements. Financial services dominate its sector allocation at 18.00%, followed by industrials at 11.00%. Top holdings include Samsung at 2.50%, Sk Hynix Inc (NASDAQ:SKHY) at 2.16%, and Asml Holding Nv (NASDAQ:ASML) at 2.11%. Launched in 2007, SPDW has paid $1.52 per share over the trailing 12 months, yielding 3.10% on its recent $49.45 share price. Geographically, the majority of its holdings are based in Europe (51%), with additional exposure in Asia Pacific (36%) and the Americas (12%). Japan leads its country allocation with 22%, followed by the United Kingdom (11%) and Canada (10%).
Which is the Better Buy?
The choice between SPGM and SPDW hinges on an investor’s existing portfolio and diversification goals. SPGM offers broader global market exposure, including the U.S., which could make it a suitable core holding for those seeking a single, diversified global equity fund. Its lower maximum drawdown over five years suggests a degree of stability, possibly due to its substantial U.S. component. However, investors specifically aiming to increase their *non-U.S.* developed market exposure should consider SPDW. SPDW’s lower expense ratio and higher dividend yield make it an attractive option for cost-conscious and income-seeking investors looking to complement a U.S.-heavy portfolio. While its ten-year performance has lagged SPGM (158% vs. 220% total return), this is largely attributable to the strong performance of the U.S. market relative to other developed markets over that period. For true ex-U.S. diversification, SPDW provides nearly 99% international stock exposure. Ultimately, both ETFs serve valuable purposes; the ‘better buy’ depends on whether an investor prioritizes comprehensive global coverage (SPGM) or dedicated developed international market exposure (SPDW).
Frequently Asked Questions (FAQ)
-
What is an ETF and why invest in global ETFs?
An ETF (Exchange Traded Fund) is an investment fund traded on stock exchanges, much like stocks. Global ETFs offer diversified exposure to multiple countries and regions, reducing reliance on a single economy and potentially enhancing returns while spreading risk.
-
What is the primary difference in exposure between SPGM and SPDW?
SPGM (State Street SPDR Portfolio MSCI Global Stock Market ETF) provides broad global equity exposure, including a significant portion of U.S. stocks (61%). SPDW (State Street SPDR Portfolio Developed World ex-US ETF) focuses exclusively on developed markets outside the U.S., making it ideal for investors seeking pure international diversification.
-
How does an ETF’s expense ratio impact my investment?
The expense ratio is an annual fee charged by the fund. A lower expense ratio, like SPDW’s 0.03%, means more of your investment returns are retained by you over time. Even small differences can significantly impact long-term portfolio growth due to compounding.
