MSCI World ETF Investors Face Pivotal Index Rule Changes

MSCI World ETF US4642863926

Investors in the iShares MSCI World ETF should mark February 10th on their calendars. On this date, index provider MSCI will not only announce its routine quarterly rebalancing but will also implement specific methodological adjustments. These changes come as the fund's portfolio continues to be heavily influenced by a significant concentration in technology stocks.

The upcoming review of the global index will follow a modified set of rules. As MSCI communicated in late January, this particular rebalancing will only account for substantial changes in a company's free float—specifically, those reaching an absolute threshold of 0.15 in the inclusion factor. These adjustments will take effect at the market close on March 2nd.

This limited scope is a preparatory step for a much more comprehensive methodological overhaul scheduled for May 2026.

Crypto-Heavy Companies Face New Limits

A notable update involves "Digital Asset Treasury Companies" (DATs)—firms holding at least 50% of their assets in cryptocurrencies. MSCI confirmed that while these entities will remain in the index, they are now subject to new restrictions. Increases in weighting for these companies are currently prohibited, and new additions or segment changes within this category have been temporarily suspended.

Geographic and Sector Concentration Remains High

A look at the ETF's current composition reveals significant concentration. At the turn of the year, the top ten holdings alone accounted for more than 27% of the fund's assets. The list is led by Nvidia (5.45%), Apple (4.85%), and Microsoft (4.11%). The information technology sector dominates the allocation with approximately 27%, followed by financials at around 17%.

Geographically, the fund maintains a strong U.S. bias: American equities constitute nearly 72% of the portfolio. Japan is a distant second, representing roughly 5.4%.

Valuation Reflects Strong Performance

The focus on technology stocks has recently paid off. Following a gain of over 21% in 2025, the ETF is trading near its record highs. The current year also began positively, with an advance of nearly 3%. This performance, however, is reflected in the fund's valuation. According to BlackRock data, the portfolio's price-to-earnings (P/E) ratio stands at an ambitious 26.10.

The February 10th announcement will provide clarity on the near-term adjustments to the global index. However, investors should already be looking ahead to May 2026, when the more extensive methodological shift takes effect. In the short term, the ETF's price movement will likely continue to depend primarily on the quarterly results and outlooks from its heavily weighted technology giants.
