IWDA vs XMME.
IWDA and XMME don't track the same index. Here's what each actually holds, then the fee, domicile and structure side by side. I show you the difference; you decide how much of the world you want to own.
First, the thing that matters most: these follow different indices. IWDA tracks MSCI World (23 developed markets, ~1,400 companies); XMME tracks MSCI Emerging Markets (emerging markets, ~1,200 companies). How much of the world you want to own dwarfs the fee gap below, so start there.
The fee, and what it costs

Each drift is measured against that fund’s own index, from trackingdifferences.com, so they aren’t a head-to-head: negative means the fund beat its index.
Checked July 2026
The structural facts (fee, domicile, structure, size) are each fund’s own, from its factsheet or KID, checked and cited. The returns come from justETF, a reputable ETF data service, so every fund is measured to the same date on the same basis: the only honest way to compare them. The tracking difference (how each fund actually did against its own index) comes from trackingdifferences.com, the standard European source. I don’t compute any of it myself, and there are still no affiliate links.
No affiliate links. No paywall. Nothing on this page is for sale, and no broker pays me to rank one fund above another. The neutrality is the whole point.
Structural facts from the funds’ own reports, returns via justETF, tracking via trackingdifferences.com. Not a recommendation, and I’m not a licensed adviser. Past returns are not a guide to future ones. Which fund suits you depends on your broker, your account and your country’s tax. Not advice.
