Five Global ETFs,
One Clear Picture
A candid look at how ACWI, VT, SPGM, and their peers have performed — and what the numbers actually mean for long-term investors.
Afew years ago, I had a conversation with a colleague who had spent nearly a decade agonizing over which global ETF to pick. He kept delaying — reading comparison tables, watching YouTube breakdowns, refreshing fund fact sheets — while the market quietly ran ahead without him. His experience made one thing clear: the difference between these major global funds is far smaller than the cost of indecision.
That insight holds up when you examine the data. SPGM, ACWI, and VT — three of the most widely held global stock market ETFs — all returned between 73% and 78% on a cumulative total-return basis from 2019 onward. That is roughly a coin toss's worth of difference for what would otherwise feel like a momentous fund selection decision.
What the Numbers Actually Say
The cumulative five-year figures tell a consistent story. SPGM came out marginally ahead at around 77.8%, followed by ACWI at 74.0% and VT at 73.7%. For context, a European-listed equivalent tracking the same MSCI ACWI benchmark posted roughly 56.8% over a similar window — the gap largely attributable to currency effects and slightly different measurement periods rather than any fundamental divergence in strategy.
| ETF | Benchmark Index | Coverage | Holdings | 5-Yr Return |
|---|---|---|---|---|
| SPGM | MSCI Global Stock Market | Global (Dev + EM) | ~1,500+ | 77.78% |
| ACWI | MSCI ACWI | 23 Dev + 24 EM | ~2,757 | 73.97% |
| VT | FTSE Global All Cap | Global (incl. small-cap) | ~9,000+ | 73.73% |
| SPDR MSCI ACWI UCITS | MSCI ACWI | Global (Dev + EM) | ~2,757 | 56.82% |
| Vanguard FTSE All-World UCITS | FTSE All-World | 90–95% global mkt cap | ~4,200+ | Similar to ACWI |
Index Architecture: More Different Than the Returns Suggest
Where these funds do diverge meaningfully is under the hood. The MSCI ACWI covers roughly 85% of global investable market capitalization through about 2,757 large- and mid-cap names. The FTSE All-World, by contrast, stretches further — approximately 4,200 to 4,280 securities, capturing 90 to 95% of the market. VT goes even broader, pulling in small-cap stocks that the other two largely ignore.
In practice, this structural difference has mattered very little to actual returns over the past five years. Both the FTSE All-World and MSCI ACWI indices produced nearly identical outcomes since 2019, with the FTSE version holding a hair-thin advantage. The takeaway is not that index choice is irrelevant, but that at this level of diversification, the bigger variables — timing, contribution consistency, and cost — carry far more weight.
The American Gravity Problem
One honest tension in all five of these products is U.S. concentration. Because they weight by market capitalization, American equities — dominated by a handful of mega-cap technology companies — absorb 60% or more of the portfolio. The S&P 500 climbed over 20% in the first ten months of 2024 alone, and that surge flowed directly into global ETF returns. This is worth naming plainly: owning a "global" ETF has, in recent years, meant owning a lot of America. Whether that continues is not a settled question.
The ETF market itself reflects enormous confidence in the model. Global ETF net inflows reached a record $1.88 trillion in 2024, pushing total industry assets to roughly $15 trillion — a 32% increase within a single calendar year. Active ETFs alone surpassed $1 trillion in assets for the first time. Capital is voting clearly for diversified, low-cost, index-driven exposure.
What to Weigh Before Choosing
For most investors, the decision between these five funds comes down to factors the performance table cannot capture. Total expense ratio matters quietly but compoundingly over decades. Whether the fund is domiciled in Ireland or the United States affects dividend withholding tax, particularly for non-U.S. holders. Currency hedging — or the absence of it — shapes the experience in local terms. And the listing exchange determines trading hours, bid-ask spreads, and liquidity.
None of these funds will make or break a retirement outcome on their own. What matters more is the habit behind the holding: regular contributions, tolerance for drawdowns, and the discipline not to sell during the stretches when the global economy looks its most frightening. The five-year returns above were earned through a pandemic, a rate cycle unlike any in a generation, and two major regional conflicts. The funds absorbed all of it.
