For years, the composition of the iShares MSCI World ETF followed a predictable trend: the steady, increasing dominance of US equities. That pattern has now reversed. In March 2026, the fund’s portfolio rebalancing resulted in a net reduction of its American holdings, marking a notable departure from the past. Concurrently, the ETF strategically moved into specific technology niches.
Macroeconomic Headwinds and Technical Indicators
The portfolio, historically comprised of over 70% US assets, is currently facing macroeconomic challenges. The persistent high-interest-rate environment maintained by the US Federal Reserve is applying valuation pressure on dominant mega-cap stocks such as Apple, Microsoft, and Nvidia.
This complex situation is reflected in recent performance figures. Since the start of the year, the ETF has declined by 4.56%, closing Friday’s session at $178.00. The 14-day Relative Strength Index (RSI), now at a level of 20.4, indicates the fund is in technically oversold territory.

Strategic Rebalancing Details
The routine index reweighting triggered significant changes within the fund. There were 18 new additions to the portfolio, set against 27 deletions. The decline in US exposure was driven by a clear asymmetry: while eight American companies were added, fifteen were removed.
Despite this pullback from US names, the ETF is not retreating from growth-oriented investments. Newly included securities like AST SpaceMobile, Coherent Corp, and FTAI Aviation reveal a deliberate strategic focus. The fund is targeting future-oriented sectors, including AI hardware and satellite-based communication technology.
A Prelude to a Major Overhaul
Market observers view the March adjustments as merely a precursor. A comprehensive methodological change to the underlying MSCI World Index is scheduled for May 2026. Analysts anticipate this shift will fundamentally reorganize the allocation for the largest technology corporations. This upcoming rebalancing is expected to generate a significantly higher portfolio turnover rate compared to the recent, relatively moderate adjustments.
