About IOO

IOO is the iShares Global 100 ETF. It tracks the S&P Global 100 Index, a list of around 100 of the world's largest multinational companies, weighted by size. It is passive and unhedged, and has been on the ASX since 2007.

This is a mega cap fund. Apple, Nvidia, Microsoft, Alphabet and Amazon make up a large share of it, so technology is the dominant sector and the US is the dominant country, with a smaller group of European and Asian giants alongside. There are no small or mid-sized companies at all. Income is modest and unfranked. Concentration in so few, very large companies can mean strong results when they lead, and bigger falls when they stumble. Being unhedged, returns move with the Australian dollar.

IOO is often used as a satellite holding by investors who want a focus on the world's biggest blue chips. Broader alternatives include VGS and BGBL, while NDQ offers a US tech tilt. See VGS vs IOO and NDQ vs IOO.

IOO distributions and dividend dates

IOO pays distributions half-yearly, usually going ex-distribution in July and December, with payment about 11 days after the ex-date.

The latest distribution was $1.8151 per unit (0% franked), ex-distribution on 1 July 2026 and paid on 13 July 2026. To receive it you need to own IOO before the ex-date.

Its distribution yield over the past 12 months is about 1.2%. Distributions vary and past payments are not a guide to future ones.

Base since 26 Oct 2026

IOO is in a base. Here's why that matters.

IOO's moving averages are tangled and the price is moving sideways. The trend hasn't picked a direction yet. Its price is 4.5% below its 12-month high.

Why it matters: Bases are where the next big move starts. A breakout can begin a new uptrend, while a breakdown can start a long fall. Buying a satellite before the breakout often means waiting months for nothing to happen.

At ETF Adviser the core of a portfolio stays invested through every stage, and satellite ETFs are only bought in an uptrend. Members get a weekly update on which ETFs are breaking out of a base and which trends have broken.
