IWDA is iShares' Core MSCI World UCITS ETF — the developed-world all-world fund, and at €110B the largest UCITS ETF in Europe. The honest take: it's broader than an S&P 500 tracker, narrower than a true all-world, and its 0.20% TER buys you 23 developed countries and nothing from the emerging world.
What's inside
| Ticker | Name | Weight |
|---|---|---|
| NVDA | NVIDIA Corp | 5.30% |
| AAPL | Apple Inc | 4.67% |
| MSFT | Microsoft Corp | 3.27% |
| AMZN | Amazon.com Inc | 2.51% |
| GOOGL | Alphabet Inc Class A | 2.09% |
The name says World; the basket says America. Every one of the top ten — NVIDIA, Apple, Microsoft, Amazon, the two Alphabet lines, Broadcom, Meta, Tesla, and JPMorgan — is a US company. MSCI World is developed markets weighted by market cap, and the US is the large majority of that by weight, so a "World" fund is in practice a US-heavy fund with Japan, the UK, and Europe filling out the tail. The top five come to 17.8% and the top ten to 25.2% — concentrated, but materially less so than a pure S&P 500 fund, because 1,308 holdings across 23 countries pull each weight down.
Costs and structure
The ongoing charge is 0.20% — €100 a year on a €50k position. Worth noticing: that's a hair more than Vanguard's VWCE at 0.19%, and VWCE throws in emerging markets for the money. On cost-per-coverage alone IWDA loses that comparison; what it offers instead is a deliberately developed-markets-only mandate and a track record stretching back to 2009. Replication is physical with optimized sampling — iShares holds 1,308 of the index's constituents rather than every name in the tail. The fund is Irish-domiciled (ISIN IE00B4L5Y983), which is the load-bearing detail for a Euro investor: the Ireland/US tax treaty trims US withholding on the dividends thrown off by all those American holdings. Dividends accumulate inside the wrapper — no cash to redeploy, no tax event until you sell. Inception was 25 September 2009, and that head start is most of why IWDA sits at €110B today while younger rivals are still catching up. Base currency is USD with no hedge, so on the LSE you buy it in dollars and your real FX exposure follows the basket, which is mostly dollars anyway. The full breakdown is on iShares' factsheet.
Performance in context
Live data temporarily unavailable for this comparison.
IWDA versus VWCE is the only comparison that really matters here, and it comes down to one thing: emerging markets. VWCE holds everything IWDA holds plus an emerging-markets slice that IWDA leaves out entirely; IWDA stops at the developed-world border. Over the past decade developed markets — really, US megacap — outran the emerging world, so IWDA has tended to edge VWCE. Whether that persists is the actual bet. Read the chart, not the last decade's headline.
Who buys it and why
IWDA is the core, not the satellite. The typical holder is a Euro investor on a Trade Republic or Scalable Capital savings plan who wants one broad developed-world position and is comfortable owning no emerging markets. The sharper reason to pick IWDA over VWCE is control: pair IWDA with a dedicated emerging-markets fund like EIMI and you can dial the EM weight yourself instead of accepting VWCE's fixed allocation. That IWDA-plus-EIMI "build your own all-world" is one of the most common two-fund portfolios in European retail for exactly that reason. If you'd rather not think about the EM weight at all, you don't need IWDA — VWCE does the blending for you in a single line.
Alternatives worth knowing
- VWCE — Vanguard's FTSE All-World: IWDA plus emerging markets in one fund, for 0.19%. The direct head-to-head is VWCE vs IWDA.
- VUAA — if you'd rather concentrate on US large-cap and skip the rest of the developed world entirely. Narrower than IWDA, and cheaper at 0.07%.
- EIMI — iShares Core MSCI EM IMI, the emerging-markets complement most IWDA holders pair it with to rebuild a full all-world on their own terms.
