MSCI World ETF Approaches Major Index Reshuffle Amid Record Performance

MSCI World ETF US4642863926

As it nears all-time highs in late January 2026, the iShares MSCI World ETF (URTH) is poised for a significant quarterly index review. Scheduled for February 10, this rebalancing carries added weight due to impending methodological shifts set by the index provider.

The fund, tracking 1,321 individual securities from developed markets, reported assets under management of approximately $6.97 billion as of January 29, 2026. It delivered a solid 21.28% return in 2025 and has continued its strong momentum into the new year, posting a 2.90% gain through January 28.

Key Portfolio Metrics:
- Price-to-Earnings Ratio: 26.44
- Price-to-Book Ratio: 3.94
- 12-Month Dividend Yield: 1.49%
- Total Expense Ratio: 0.24%

A substantial portion of the ETF’s holdings remains in technology. The three largest positions—NVIDIA, Apple, and Microsoft—collectively account for roughly 14% of the portfolio. NVIDIA leads with a weighting of about 5.3%, underscoring the continued investor focus on artificial intelligence infrastructure.

Reflecting its market-cap-weighted methodology and the historical outperformance of U.S. equities, American stocks dominate the fund with a weighting exceeding 70%.

Upcoming Review Introduces New Methodology

On January 27, 2026, MSCI announced a notable adjustment for the forthcoming review. Only significant free-float changes will be implemented, specifically those meeting an absolute threshold of 0.15 for the Foreign or Domestic Inclusion Factor. This limited scope is a preparatory step for a broader methodological overhaul scheduled for full implementation in May 2026.

All changes resulting from the February review will take effect on March 2, 2026.

Digital Asset Companies Retain Inclusion

In a separate decision, MSCI has opted to keep Digital Asset Treasury Companies (DATs) within the index. These are firms whose cryptocurrency holdings constitute at least 50% of their total assets. While the index provider had previously considered their removal, it has reversed course.

However, new restrictions will apply: no further increases in weighting will be applied to DATs, and any new additions or segment changes for such companies will be postponed. This affects entities like Strategy (formerly MicroStrategy), known for its substantial Bitcoin reserves.

Liquidity and Forward Outlook

The ETF maintains robust average daily trading liquidity of over 400,000 shares, solidifying its position as a core vehicle for gaining exposure to global equity markets. The high concentration in the technology sector, however, leaves it particularly sensitive to quarterly earnings reports and forecasts from the semiconductor and AI industries.

The specific additions, deletions, and weighting adjustments MSCI will announce on February 10 are likely to generate notable activity, especially within tech holdings. The coming weeks will reveal how the index provider navigates the balance between methodological consistency and the evolving landscape of digital assets.
