iShares Core MSCI International Developed Markets ETF

BlackRock's iShares Core MSCI International Developed Markets ETF (IDEV) is a one-fund way to own about 2,330 large, mid-size and small company stocks from developed countries outside the United States, following the MSCI World ex USA Investable Market Index. Its yearly fee of 0.04% is well below the 0.11% average of similar funds, though two rivals charge 0.03%. Japan, the UK and Canada were its largest country weights as of July 31, 2026.

• Over the year to Nov 2, 2026, IDEV returned +14.6%, 5th of 9 among similar funds.
• Its 5-year annualized return was +8.5%.
• In the 2020 COVID crash it fell 33.8% and regained its old high 7.6 months after the low.
• Its worst full calendar year was 2022 (-15.0%); its best was 2025 (+32.6%).
• The deepest fall in its price history was 34.8% (Jan 17, 2020 to Mar 23, 2020), recovered by Nov 11, 2020.

As of Jul 31, 2026, the fund held 2,330 securities; the ten largest made up 10.75% of assets.

• Over the three months to Jul 31, 2026, investors added a net $1.53B (creations minus redemptions, per the N-PORT report).
• Monthly total returns reported for that quarter: +2.39%, -0.25%, +1.67%.

IDEV tracks the MSCI World ex USA Investable Market Index, a benchmark for developed-market stocks outside the United States. As of July 31, 2025, it covered large, mid-size and small companies in 22 countries or regions, including Japan, the UK, Canada, Switzerland and Australia. The index is weighted by market value and free float-adjusted: bigger companies get bigger weights, counting only shares available to public investors. MSCI, not BlackRock, decides what goes in.

BlackRock Fund Advisors doesn't try to beat the index or retreat to cash when markets fall. It uses representative sampling: it holds a set of stocks chosen to match the index's overall size, industry and yield profile, so it may not own every name. At least 80% of assets go into index stocks or close equivalents. Up to 20% can go into futures, options, swaps, cash and other securities that help it track. As of July 31, 2026, it held about 2,330 stocks plus tiny futures positions on indexes such as the FTSE 100 and TOPIX.

Trading is light: portfolio turnover, the share of holdings replaced in a year, was 3%. The fund may lend up to one-third of its assets for a fee. And since its value is counted in dollars, a stronger dollar can cut returns even when foreign stocks rise.

• IDEV charges 0.04% a year, versus an average of 0.11% for the similar funds below (3rd of 9, cheapest first).
• Using the prospectus's standard example, $10,000 invested would cost about $4 in the first year and $51 over 10 years (assuming a 5% annual return).

With about 2,330 stocks across developed markets outside the US and a 0.04% fee, it can serve as the main international stock holding next to a US stock fund.

IDEV adds companies a US-only portfolio misses; as of July 31, 2026, Japan alone was about 22% of assets. It launched in 2017, so it missed the 2008 crisis. Its deepest drop, 34.8%, came in the 2020 COVID crash, and it regained that peak by November 2020. The 2022 bear market cut it 28.3%, and recovery took about 17 months from the low, until February 2024. Its worst calendar year was 2022, down about 15%. Selling shares for spending in a slump like that locks in losses.

Dividends come twice a year, with a trailing 12-month yield of 3.2% as of October 27, 2026. A stronger dollar can also trim returns. Costs are small: 0.04% a year, or $51 over 10 years on $10,000 in the SEC's standard example. Past results don't predict future ones, and a plan should look at the whole portfolio, not one fund.
