Is IOO a good ETF?
IOO is the iShares Global 100 ETF from iShares. It tracks the S&P Global 100 Index. We classify it under Intl, Large-Cap, and Market-Cap. With about $5.83 billion in assets it is a large, highly liquid fund. Listed on the ASX since 2007-10-29 (almost 19 years ago).
On a total-return basis, IOO has delivered 16.99% a year over 10 years (ranked 3rd of 108 ETFs we track), 16.63% a year over 5 years (ranked 10th of 188 ETFs we track), 21.31% a year over 3 years (ranked 22nd of 226 ETFs we track), and 16.94% a year over 1 year (ranked 68th of 308 ETFs we track). Its strongest showing is over 10 years, where it sits in the top 3% of all ETFs we track.
The management fee of 0.4% is reasonable. That's cheaper than the typical 0.48% for similar ETFs. If cost is your priority, IVV (0.04%) and U100 (0.18%) cover similar ground for less. It pays a low 1.2% yield, so most of its return must come from capital growth.
Over the past 10 years its volatility has been moderate (annualised standard deviation around 11.52%), meaning the kind of swings you'd expect from a diversified equity fund. Its 10-year Sharpe ratio of 1.24 is strong — that's the return it has earned per unit of risk taken (higher is better).
Portfolio turnover is very low at about 4% a year — the portfolio barely changes from year to year, much like a classic buy-and-hold index fund. Very little of its return is lost to trading or to capital gains being realised early, making it highly tax-efficient.
Strengths
- Top-3% returns over 10 years (3rd of 108 ETFs we track).
- Low-cost: a 0.4% management fee keeps more of the return in your pocket.
- Strong risk-adjusted returns (10-year Sharpe ratio 1.24).
Things to watch
- Cheaper alternatives exist: IVV and U100.
Good to know
- Low 1.2% yield — this is a growth-oriented fund, not an income play.
What IOO's categories mean for you
How each category this ETF belongs to tends to behave across market cycles.
Global and international shares from outside Australia — broadening you into thousands of companies and the sectors (tech, healthcare) the local market lacks.
- Market regime
- Essential diversification away from the bank-and-resources-heavy ASX. Unhedged versions carry currency risk; hedged versions remove it at a small cost.
- In a portfolio
- A core holding for almost every long-term Australian portfolio.
The biggest, most established companies. More stable earnings, lower volatility and often steadier dividends than the broad market.
- Market regime
- Holds up comparatively well in downturns and uncertain markets; tends to lag small-caps and growth during the most aggressive bull runs.
- In a portfolio
- A dependable core building block suited to long-term holding.
Holdings are weighted by company size, so the largest companies carry the most weight. These funds are cheap, tax-efficient and self-rebalancing.
- Market regime
- Works in almost any regime as a low-maintenance core. The trade-off is concentration — you automatically own more of whatever has already become expensive at the top of a bull market.
- In a portfolio
- The classic buy-and-hold core of most portfolios. Well suited to long-term, hands-off investing.
