Key Fact

IOO has a portfolio turnover rate of just 6% per year — well below the 60% category average. This very low turnover makes it one of the most tax-efficient international ETFs on the ASX for buy-and-hold investors.

Suited for

Investors who want exposure to globally dominant multinational businesses. The S&P Global 100 specifically targets companies with cross-border revenue, not just large domestic businesses.

Risks

Concentrated in the same US mega-caps that dominate VGS and BGBL. The 100-stock limit means less diversification than broader international funds. The 0.40% MER is significantly higher than VGS or BGBL.

Frequently Asked Questions - IOO

Why has IOO outperformed broader global ETFs like VGS and IWLD recently?+
IOO's concentrated portfolio of just 100 of the world's largest companies has benefited enormously from the mega-cap technology rally, with Apple alone exceeding 10% of the fund. Its 19.8% one-year return outpaced VGS (18.2%) and IWLD (17.8%) because mega-caps like Microsoft, NVIDIA, and Amazon have driven disproportionate global market returns. However, this concentration is a double-edged sword - IOO would underperform significantly if mega-cap leadership rotates to smaller or value-oriented stocks.
Is IOO's 0.40% MER justified given cheaper alternatives like BGBL exist?+
IOO's 0.40% MER is five times higher than BGBL's 0.08%, which is a significant cost drag over long holding periods. On a $100,000 investment, that's roughly $320 more per year in fees. IOO's only justification is if you specifically want concentrated mega-cap exposure rather than broad market diversification. Most Australian investors would achieve better risk-adjusted outcomes using BGBL or VGS as a core holding and adding individual mega-cap stocks if desired.
How does IOO's extreme concentration risk compare to holding VGS?+
IOO holds just 100 stocks versus VGS's approximately 1,500, with its top 10 holdings often comprising over 50% of the portfolio. A single stock like Apple can exceed 10% weighting, meaning one company's earnings miss could significantly impact returns. VGS spreads risk far more broadly across sectors and market-cap ranges within developed markets. IOO suits Australian investors who have a deliberate conviction in global mega-cap dominance, not those seeking diversified core international exposure.
Who should consider IOO in an Australian investment portfolio?+
IOO suits Australian investors who want a satellite holding to overweight the world's most dominant multinational companies alongside a broader core fund like VGS or IWLD. Its 1.52% yield is the highest among major global ETFs on the ASX, appealing to income-oriented SMSF portfolios, though distributions carry no franking credits. IOO is not ideal as a sole international holding due to concentration risk, but it can complement a diversified portfolio for investors bullish on global mega-cap quality and pricing power.
