Sector Breakdown
How This Works
Membership source: Downloaded daily from the BlackRock iShares IOZ ETF holdings. Any stock held by IOZ is treated as an ASX 200 member.
Buffer zone (updated Sep 2025): S&P uses a 20-position buffer. A non-member must reach rank ≤ 179 to be added; a member must fall to rank ≥ 221 before removal. This prevents excessive turnover.
Addition candidates: Non-members ranked ≤ 190 globally by market cap — within or approaching the 179 addition threshold. Rank shown in green when inside the zone.
Removal candidates: Current members ranked ≥ 185 globally — drifting toward the 221 removal threshold. Rank shown in red when approaching the danger zone.
Lookback period: S&P uses the 3-month average float-adjusted market cap (since Sep 2025), so short-term price moves matter less than sustained rank changes.
Short data: From ASIC's daily short position reports. Percentage = shares sold short as a proportion of issued capital.
Estimates use total market cap, not float-adjusted. Liquidity screens also apply. Treat as directional, not definitive.

What Is the S&P/ASX 200?
The S&P/ASX 200 (ticker: XJO) is Australia's primary benchmark index, maintained by S&P Dow Jones Indices. It tracks the 200 largest ASX-listed companies by float-adjusted market capitalisation, representing approximately 80% of the total market value of the Australian Securities Exchange.
The index includes companies across all GICS sectors — from the big four banks (CBA, NAB, WBC, ANZ) and mining giants (BHP, RIO) to healthcare, technology, and real estate. Membership is not simply the 200 largest stocks; S&P applies liquidity screens requiring a minimum average daily turnover relative to market cap.
How Often Does the ASX 200 Change?
The S&P/ASX 200 rebalances quarterly, with effective dates on the third Friday of March, June, September, and December each year. S&P Dow Jones Indices announces the changes approximately four weeks before the effective date, giving investors time to prepare.
Between announcements and effective dates, stocks slated for removal often see increased short selling as traders anticipate passive fund outflows. Stocks being added typically attract buying interest. This creates predictable short-selling patterns around rebalance events.
How Are Addition & Removal Candidates Identified?
S&P Dow Jones Indices uses a buffer zone to minimise unnecessary turnover. A stock outside the index must rank in the top 179 by float-adjusted market cap to be added. A current member must fall to rank 221 or lower before it is removed. This 20-position buffer (updated September 2025) means a brief dip below rank 200 does not trigger removal.
Our addition candidates show non-members ranked in the top 190 — within or approaching the 179 addition zone. Our removal candidates show current members ranked 185th or lower globally, approaching the 221 removal threshold. Rankings use total market cap; S&P uses the 3-month average float-adjusted figure, so these estimates are directional only.
Short Selling & the ASX 200
Short sellers target ASX 200 stocks for various reasons: index rebalancing (shorting stocks likely to be removed before passive fund selling hits), sector rotation, and hedging long positions in index funds. Short interest data on this page comes from ASIC's daily short position reports, which reflect the total number of shares sold short as a percentage of issued capital.
Large ASX 200 stocks typically have lower short interest percentages (1–4%) due to their size and liquidity. Elevated short interest (above 5%) in an index member often signals either a structural short thesis or index rebalancing activity.
