IWDA Holdings: What Stocks Are in the iShares Core MSCI World ETF?

IWDA is one of the most popular ETFs among European investors, and it shows up in many savings plans under three different names: IWDA, EUNL or SWDA. Many people who hold it couldn’t say what they actually own beyond “the world”. Here is what is inside, with figures from August and October 2026.

IWDA, EUNL, SWDA: one fund, three tickers

All three are the iShares Core MSCI World UCITS ETF (ISIN IE00B4L5Y983). The ticker depends only on where you buy it:

• IWDA: London Stock Exchange in US dollars, and Euronext Amsterdam in euros
• EUNL: Xetra and other German exchanges, in euros
• SWDA: London in pounds, and Borsa Italiana in euros

The holdings, the fee and the performance in the fund’s currency are the same whichever ticker you buy. A few key facts:

• Index: MSCI World, large and mid caps from 23 developed countries
• Holdings: about 1,250 stocks (iShares, 21 October 2026)
• Fee (TER): 0.20% per year
• Dividends: reinvested (accumulating)
• Replication: physical, with optimized sampling
• Size: about USD 150 billion, which makes it one of the largest ETFs in Europe
• Launched: September 2009

The top 10: a quarter of the fund in ten companies

The MSCI World is weighted by market value, so the largest companies carry the most weight. At the end of August 2026 the ten largest positions were:

1. NVIDIA: 5.5%
2. Apple: 5.1%
3. Microsoft: 3.9%
4. Amazon: 2.7%
5. Alphabet (Class A): 2.2%
6. Broadcom: 1.8%
7. Alphabet (Class C): 1.7%
8. Meta Platforms: 1.4%
9. Micron Technology: 1.2%
10. Tesla: 1.2%

Together they make up 26.6% of the fund. Count Alphabet’s two share classes as one company and it moves into fourth place. All ten are American, and five of them are technology or semiconductor companies; the other five are tech-driven platforms like Amazon, Alphabet and Meta. The order shifts as prices move, but this concentration is the most important thing to understand about IWDA: a “world” ETF whose results depend heavily on a handful of US tech giants.

Country allocation: 70% United States

The remaining sixth is spread across countries such as France, Switzerland, Germany, Australia and the Netherlands. The US weight isn’t a choice made by iShares; it simply reflects how large US companies are in global market value. When US stocks outperform, the share grows, and when they lag, it shrinks.

Sectors: a third in technology

According to justETF’s classification at the end of August 2026, technology accounts for about 36% of the fund, financials for about 18%, industrials for just under 10% and health care for about 9%. The rest is spread across consumer goods, communication services, energy, materials, utilities and real estate.

Sector shares differ slightly between data providers, because each classifies some companies differently (Amazon and Alphabet, for example). The overall picture is the same everywhere: IWDA has a clear tech tilt.

What IWDA does not hold

The name says “World”, but the MSCI World leaves out two things:

• Emerging markets. China, India, Taiwan, Brazil, South Africa and other emerging economies are not included. TSMC, for example, isn’t in IWDA, even though it’s one of the largest companies in the world.
• Small caps. Only large and mid-sized companies are included. Thousands of smaller listed companies are missing.

That’s the main difference from the alternatives. The Vanguard FTSE All-World (VWCE) adds emerging markets and holds more than 3,700 stocks. The SPDR MSCI ACWI IMI goes further and adds small caps, for about 4,500 stocks. Almost everything in IWDA is also in those two funds, so holding IWDA and VWCE mostly means owning the same companies twice. How much do two ETFs overlap? shows how to put a real number on that.

Many investors deliberately combine IWDA with a separate emerging-markets ETF, often in a 70/30 or 80/20 split, to control the emerging-markets share themselves. Others prefer a single fund that already includes them. Both approaches are valid; what matters is knowing which one you’ve actually built.

See what you really own

The figures above describe the fund. What matters to you is your whole portfolio: IWDA plus whatever else you hold. If you track your portfolio with Parqet, its X-Ray export breaks every ETF down into the individual companies inside it. Pecuniator reads that export on your Mac or Windows PC, offline, and shows your real exposure by country, region and sector across all your holdings. Its Compare view puts two funds or portfolios side by side, for example IWDA and VWCE, and shows exactly where they overlap.
