ETF X-Ray: What's Actually Inside a Fund

Two ETFs with near-identical names can hold very different things. Sector donuts, holdings flows and fee twins — how to see inside a fund before comparing it to anything.

An ETF’s name is marketing; its holdings are the product. Two funds with near-identical names can differ completely in sector tilt, country exposure and concentration — and the difference only shows up when the composition is laid out: which sectors, which countries, which ten companies actually dominate the basket.

Below, a full x-ray of one of Europe’s most widely held funds — the iShares Core MSCI World ETF — from sector donut to holdings flow, plus a “fee twin”: a fund with nearly the same exposure at a very different yearly cost.

X-ray any ETF before choosing it

Two ETFs with near-identical names can hold very different things. The ETF page on Slowio opens one up before it is chosen: what it actually holds, how it spreads across sectors and regions, what it costs each year. Here is that x-ray for one of the largest world ETFs Slowio follows:

Donut chart: sector allocation of iShares Core MSCI World UCITS ETF USD — Technology is the largest sector at 33.0% of assets
iShares Core MSCI World UCITS ETF USD — allocation by sector, drawn as the app’s composition donut: Technology leads at 33.0% of assets; the 3 smallest sectors are grouped as Other (6.7%).

The same page’s flow view — fund to sector to stock for the 10 largest holdings, together 27.9% of assets; band widths are each holding’s share of the fund, and NVDA is the single largest at 5.9%.

Behind the charts, the page condenses the fund facts that take longest to dig out of a factsheet:

Technology

One number in that band deserves a second look: the fee. SPDR® MSCI World UCITS ETF (SWRD.LSE) tracks the same index (it is in both names), 74% North America to 75% — yet its yearly cost is 0.12% to 0.20%: the larger fund charges 1.7× as much for near-identical exposure. The Score tab of the ETF page puts that in one picture — the largest score gap is Cost, 19 points:

Each score measures the fund as a product against a reference value set for its family of funds: meeting the reference gives 75, and no fund reaches 100. They describe the fund as it is today — not what it will return. See the Score tab →
