The MSCI World ETF’s Heavy Reliance on U.S. Tech Giants

MSCI World ETF US4642863926

While its name implies broad international exposure, investors in this popular exchange-traded fund are making a concentrated bet on the economic strength of the United States. The fund has surged more than 20% since the start of the year, a performance driven overwhelmingly by the boom in American technology stocks. As other global regions act as a drag on returns, a critical question emerges: does this "world" fund still offer sufficient diversification for the period ahead?

The fund's strategy is shaped by two key themes looking toward late 2025: the exceptional position of the U.S. market and expectations for declining interest rates. Although the underlying index captures approximately 85% of the market capitalization across 23 developed countries, the U.S. weighting has now climbed to exceed 70%.

This results in a portfolio that is extremely concentrated at the top, despite containing over 1,300 individual holdings. The ten largest positions account for nearly 28% of the total fund assets, representing a significant concentration risk.

Leading the list is Nvidia (5.34%), which has cemented its top position thanks to sustained infrastructure spending on artificial intelligence. It is followed by Apple (4.98%) and Microsoft (4.11%), which serve as defensive anchors with robust cash flows. The inclusion of more cyclical names like Broadcom and Tesla within the top ten further highlights the fund's high sensitivity to technology sector demand.

Sector and Geographic Imbalance

From a sector perspective, information technology dominates the fund's composition, representing between 25% and 30% of holdings. This places it far ahead of financials and healthcare. Geographically, markets such as Japan (~5.4%) and the United Kingdom (~3.8%) now play only minor supporting roles.

Market observers note a shift in sentiment is currently underway. The indiscriminate "AI-at-any-price" trading that characterized the early part of the year is giving way to a phase where concrete profit growth is demanded. The anticipated interest rate cut from the U.S. Federal Reserve in December is seen as crucial fuel to justify the tech sector's ambitious valuations.

How It Differs from Broader Alternatives

A key distinction from "All World" products is this ETF's deliberate exclusion of emerging markets. It completely avoids markets like China, India, and Brazil. This approach provides a more stable regulatory profile, free from the uncertainties associated with Beijing's policies, but it also means investors forgo potential growth surges from these developing economies.

The immediate focus for the fund rests on the upcoming decision from the U.S. central bank. Should the rate cut currently priced in for December materialize, it is expected to act as a stabilizer for equity valuations, potentially laying a solid foundation for the start of the 2026 trading year.
