This geographic spread mitigates the risk of overconcentration in any single region, a key consideration as global economic imbalances persist.

The fund's alignment with the MSCI ACWI ex USA Index ensures a market-cap-weighted approach that mirrors the global equity landscape outside the U.S. While specific sector allocations for 2025 are not explicitly detailed in recent reports, the technology sector accounts for approximately 9.80% of the fund's assetsGlobal ex-U.S. ETF List - ETF Database, [https://etfdb.com/etfs/region/global-ex-us/]^[6]. This weighting captures growth in tech-driven economies, including both developed markets (e.g., Germany's industrial tech firms) and emerging markets (e.g., India's software sector).

Alignment with Global Growth Trends

The 2025 investment landscape is defined by two megatrends: the rise of emerging markets and the dominance of technology. IXUS, while not exclusively focused on either, offers indirect exposure to both. Emerging markets constitute a smaller portion of the fund's portfolio compared to dedicated emerging market ETFs like IEMGiShares Core MSCI Emerging Markets ETF | IEMG, [https://www.ishares.com/us/products/244050/ishares-core-msci-emerging-markets-etf]^[7], but their inclusion ensures investors benefit from the long-term growth potential of economies such as India and Indonesia.

Meanwhile, the technology sector's 9.80% weightingGlobal ex-U.S. ETF List - ETF Database, [https://etfdb.com/etfs/region/global-ex-us/]^[6] aligns with the global shift toward innovation-driven economies. As artificial intelligence, semiconductors, and automation reshape industries, IXUS's diversified tech exposure positions it to capture gains from these transformative trends. This is further supported by iShares' 2025 investment outlook, which emphasizes the strategic value of international equities and tech-driven assets in a declining U.S. dollar environment2025 Fall Investment Directions | iShares, [https://www.ishares.com/us/insights/investment-directions-fall-2025]^[8].
