The MSCI World ETF Approaches New Peaks Amidst a Shifting Global Landscape

As 2025 draws to a close, the iShares MSCI World ETF (ticker: URTH) is trading near its record high, having delivered investors an approximate 20% return for the year. This performance is being fueled by two concurrent trends: sustained strength in the U.S. technology sector and a notable recovery in non-U.S. markets, the latter amplified by a weakening U.S. dollar. However, a deep dive into the fund’s holdings raises a critical question about its diversification, revealing a portfolio heavily concentrated in a handful of American tech giants.

A Broader Market Participation Emerges

The investment theme for 2025 could be characterized as “Quality Growth.” The primary engine remains the U.S. economy, but currency movements provided a significant secondary boost. A decline in the U.S. dollar’s value, which depreciated by roughly 9% over the year, created a tangible tailwind for European and Japanese equities within the index. For dollar-based investors, this currency shift mechanically increased the value of these international holdings.

Furthermore, market breadth has shown marked improvement. Whereas returns in early 2024 were almost solely driven by U.S. mega-cap stocks, contributions from financial and industrial companies across G7 nations are now bolstering performance by year-end 2025. This suggests a more widespread economic stabilization that extends beyond the initial excitement surrounding artificial intelligence.

Underlying Concentration: A Closer Look at Holdings

Despite its global mandate, the ETF’s composition reveals a significant imbalance. The ten largest positions alone account for about 27% of the entire fund’s assets. With the United States representing approximately 70% of the geographic weighting and the information technology sector constituting nearly a quarter of the portfolio, the product increasingly resembles a diversified U.S. growth fund with an international supplement rather than a purely global allocation.

Should investors sell immediately? Or is it worth buying MSCI World ETF?

A snapshot of the leading holdings includes:
* NVIDIA (5.46%): Continues as the foremost performance driver, powered by unrelenting demand for its AI hardware.
* Apple (4.84%): Serves as a defensive growth anchor, supported by its robust and stable cash flow.
* Microsoft (4.11%): Benefits significantly from its expansive cloud computing and software businesses.

Notably, JPMorgan Chase, with a weighting just above 1%, stands alone in the top ten as the sole constituent not originating from the technology or communication services sectors.

Strong Momentum and Efficient Execution

The fund’s price action underscores its current positive trajectory. Trading at $187.81 in late December, URTH posted a weekly gain of 1.42%. From an operational standpoint, the ETF functions efficiently. Its tracking error against the benchmark MSCI World Index remains negligible, and high liquidity ensures tight bid-ask spreads, allowing investors to trade close to the fund’s net asset value (NAV).

The outlook for URTH remains favorable as long as the investment cycle in AI infrastructure persists and major developed economies continue to stabilize. Nevertheless, performance in 2026 will likely hinge on the ability of the dominant U.S. technology titans to justify their elevated market valuations.
