iShares Core S&P/ASX 200 ETF (ASX: IOZ) offers a simple way to invest in the Australian share market.
This indices-tracking ASX exchange-traded fund (ETF) seeks to mirror the total returns of the S&P/ASX 200 Index (ASX: XJO).
This means IOZ ETF investors own a piece of each of Australia's top 200 listed companies by market capitalisation.
According to the latest ASX data, Australians have almost $8.69 billion invested in the IOZ ETF.
Today, the IOZ ETF's portfolio has changed because the ASX 200 Index has been updated.
Every quarter, S&P Dow Jones Indices rebalances Australia's leading indexes, including the ASX 200.
Some companies are added, and some are taken out, depending on how their valuation has changed and other criteria.
The June quarter rebalance takes effect today.
When the index changes, BlackRock is compelled to update the IOZ ETF holdings to match the index.
This ensures investors will receive returns that mirror the performance of the index, minus management fees.
