MSCI World vs S&P 500 ETF 2026 — which index is better?
MSCI World or S&P 500 — the ultimate direct comparison 2026: performance, diversification, costs and which ETF is right for whom.
The short answer
The S&P 500 has clearly beaten the MSCI World over the past 10–15 years — mainly thanks to US tech dominance (Apple, Microsoft, Nvidia, Amazon, Alphabet). The MSCI World on the other hand offers more geographical diversification with around 30 % outside the US. Anyone betting on US outperformance picks the S&P 500. Anyone who does not want to bet on a single country chooses the MSCI World.
Note: the MSCI World itself is about 70 % US equities — the difference in practice is smaller than many think.

BMInsider verdict: which one should I pick?
You do not want to bet 100 % on the US and want real geographic diversification across 23 countries. Psychologically easier when US markets fall.
You believe in the long-term strength of the US economy and US tech and want to invest as cheaply as possible (TER 0.07%).
Many investors choose e.g. 70 % S&P 500 + 30 % MSCI World ex-USA or VWCE as all-in-one. This way you participate in US growth and still keep global diversification.
Frequently asked questions — MSCI World vs S&P 500
Has the S&P 500 beaten the MSCI World long term?
Yes — over the past 10–15 years the S&P 500 has clearly outperformed the MSCI World (about 13 % vs 10 % p.a. in EUR). The main reason is the dominant performance of US tech (Magnificent 7). Whether that continues is uncertain.
What percentage of the MSCI World is the US?
As of 2026, the MSCI World is about 70–72 % US stocks. The index is therefore more US-heavy than many think — European stocks make up only ~15 %, Japan ~5 %.
Which ETF is cheaper — MSCI World or S&P 500?
S&P 500 ETFs are cheaper: the iShares Core S&P 500 (SXR8) costs only 0.07 % TER, while the cheapest MSCI World ETF (XDWD) is at 0.12 %. On €100,000 over 30 years that adds up to a noticeable difference.
What is the difference between EUNL and SXR8?
EUNL (iShares Core MSCI World) = ~1,500 stocks, 23 developed markets, TER 0.20 %. SXR8 (iShares Core S&P 500) = 500 US stocks, US only, TER 0.07 %. EUNL is more broadly diversified, SXR8 has historically delivered stronger returns.
Can I combine MSCI World and S&P 500?
In theory yes, but it makes little sense: the MSCI World already contains ~70 % US stocks. Holding both often results in 80–85 % US — similar to a pure S&P 500 but more expensive. Better: MSCI World + a separate ex-USA ETF, or simply VWCE.
