MSCI World vs S&P 500 ETF 2026 — Which Index is Better?
MSCI World or S&P 500 — the definitive 2026 comparison: performance, diversification, costs and which ETF is right for you.
The Short Answer
The S&P 500 has clearly outperformed the MSCI World over the last 10–15 years — mainly due to US tech dominance (Apple, Microsoft, Nvidia, Amazon, Alphabet). The MSCI World offers broader geographic diversification with ~30% outside the US. If you believe US exceptionalism continues, take the S&P 500. If you prefer not to bet everything on one country, the MSCI World is your answer.
Note: the MSCI World is already ~70% US stocks — the practical difference is smaller than most people assume.

BMInsider Verdict: Which Should You Choose?
You want genuine geographic diversification and don't want to bet 100% on the US. Europe, Japan, Canada and Switzerland all included. Psychologically easier when US markets drop.
You believe in the long-term strength of the US economy and want the cheapest TER available (0.07%). Historically the stronger performer over the last 15 years.

FAQ — MSCI World vs S&P 500
Has the S&P 500 beaten the MSCI World long term?
Yes — over the last 10–15 years the S&P 500 has significantly outperformed the MSCI World (approximately 13% vs 10% p.a. in EUR). This was driven mainly by US tech mega-caps. Whether this continues is uncertain.
How much of the MSCI World is US stocks?
As of 2026, the MSCI World is approximately 70–72% US stocks. European stocks account for ~15%, Japan ~5%. The index is far more US-heavy than many investors realise.
Which is cheaper — MSCI World or S&P 500 ETF?
S&P 500 ETFs are significantly cheaper. The iShares Core S&P 500 (SXR8) costs just 0.07% TER, while the cheapest MSCI World ETF (XDWD) charges 0.12%. On €100,000 over 30 years this makes a meaningful difference.
Can I hold both MSCI World and S&P 500?
Technically yes, but it rarely makes sense. Since the MSCI World is already ~70% US stocks, holding both gives you ~80–85% US — similar to a pure S&P 500 but with higher combined TER. Better alternatives: MSCI World + ex-USA ETF, or simply VWCE.
What is the best S&P 500 ETF in Europe?
The iShares Core S&P 500 UCITS ETF (SXR8) with TER 0.07% and €80bn+ AUM is the top pick. The Vanguard S&P 500 UCITS ETF (VUSD) is equally good. Both are physically replicated and available across all major European brokers.
