Australian investors rely on the S&P/ASX 200 as their primary market benchmark, but its concentrated sector mix means it behaves very differently from global indices like the S&P 500. It is the go-to yardstick for the local share market, covering 200 of the biggest companies listed on the ASX. Whether you are sizing up a super fund or thinking about your first ETF, this index is probably already influencing your portfolio.

Which country has the ASX 200 index?
What is the S&P/ASX 200?
- The S&P/ASX 200 is the stock market index of Australia. It measures the performance of the 200 largest index-eligible stocks listed on the Australian Securities Exchange by float-adjusted market capitalization (S&P Dow Jones Indices (index provider)).
- It represents about 80% of the market value of the Australian equity market (HSBC Australia (investment guide)).
- The index is maintained by S&P Dow Jones Indices and is reviewed quarterly (Mitrade Australia (trading platform research)).
Who manages the index?
- S&P Dow Jones Indices manages the S&P/ASX 200, using a market-cap weighted methodology so larger companies have greater influence on performance (Mitrade Australia (trading platform research)).
- It replaced the All Ordinaries as Australia’s main benchmark when it was rebranded in 2000 (Mitrade Australia (trading platform research)).
The implication: The ASX 200 is the default benchmark for Australian investors, representing a broad cross-section of the national economy.
Why can’t I buy the ASX 200 directly?
What does ‘buying an index’ mean?
- An index is a measurement tool, not a basket of securities you can purchase directly.
- The ASX 200 tracks the performance of 200 stocks, but you cannot buy a share of the index itself.
What are the alternatives?
- You can buy ETFs that track the index, such as iShares Core S&P/ASX 200 ETF (IOZ) or BetaShares Australia 200 ETF (A200) (The Motley Fool Australia (financial media)).
- Futures and CFDs also allow you to trade the index without owning the underlying stocks (Mitrade Australia (trading platform research)).
Index trackers like IOZ and A200 give you diversified exposure for a low fee, but you will never outperform the market — you are the market.
The catch: You cannot buy the index itself, but ETFs, futures, and CFDs all offer practical workarounds, each with different costs and risks.
How to trade or invest in the ASX 200?
What are ASX 200 ETFs?
- The most popular ASX 200 ETFs include STW (SPDR S&P/ASX 200), IOZ (iShares Core S&P/ASX 200), and A200 (BetaShares Australia 200) (The Motley Fool Australia (financial media)).
- BlackRock describes iShares S&P ETFs as a low-cost way to invest in large, well-established companies (BlackRock Australia (asset manager)).
How to trade ASX 200 CFDs?
- CFDs (contracts for difference) allow leveraged trading on the index price, but they carry high risk and are not suitable for beginners.
- The S&P/ASX 200 is suitable for futures and CFD trading because most of its constituents are highly liquid (Mitrade Australia (trading platform research)).
What are the key risks?
- Market risk: the index can fall sharply during downturns, as seen in 2020 when it dropped from above 7,000 points to around 5,000.
- ETFs carry management fees, though STW charges 0.05% p.a., making it one of the cheapest.
- CFDs introduce leverage risk — you can lose more than your initial deposit.
Six steps to start investing in the ASX 200:
- Open a brokerage account (e.g., with CommSec, SelfWealth, or Stake).
- Fund the account with at least A$500 to cover one ETF unit (e.g., A200 trades around A$100 per unit).
- Decide which ETF suits your goal: IOZ for low fees (0.09%), STW for track record (since 2000).
- Place a market order during ASX trading hours (10:00–16:00 AEST).
- Set up a regular investment plan (some brokers allow fractional shares or automated buys).
- Monitor and rebalance annually – no need to time the market.
The takeaway: Most investors are best served by choosing a low-cost ETF and holding it for the long term.

ASX 200 Pros

ASX 200 Cons
- Concentrated in financials and materials (~50%)

- Smaller universe of companies (200 vs 500)
S&P 500 Pros

- Diversified across 11 sectors
- Exposure to global tech leaders
S&P 500 Cons
- Currency risk for Australian investors

What is the average 30-year return of the ASX 200?
How is the average return calculated?
