S&P/ASX 200 Index — Level, Chart & Constituents

What the S&P/ASX 200 measures

The S&P/ASX 200 is a market-capitalisation-weighted index that tracks the share prices of the 200 largest companies listed on the Australian Securities Exchange. It is the primary barometer of the Australian equity market and part of the broader global Indices directory. Because it is weighted by market capitalisation, larger companies have a greater influence on the index level than smaller ones.

Key numbers explained

• The current S&P/ASX 200 level is 8,765.3 points, which represents the aggregate market value of the constituent companies relative to a base value.
• Today's trading range was 8,742.7 – 8,791.9, showing the intraday low and high for the session.
• The price change today is +0.09%, indicating a modest positive move over the previous close.
• The 52-week range is 8,262.4 – 9,296.7, showing the lowest and highest levels the index has reached over the past year.
• The index is denominated in AUD, so its movements reflect both local share-price changes and currency effects for international investors.
• The market-capitalisation weighting means that a large company's share-price move has a proportionally larger impact on the index level than a small company's move.

What to watch

The S&P/ASX 200 is sensitive to commodity prices, global trade flows, and regional policy shifts in the Asia-Pacific area. Investor sentiment can be influenced by developments in major trading partners, interest-rate expectations set by the Reserve Bank of Australia, and global risk appetite, which is often reflected in movements in indices such as the KOSPI, Hang Seng Index, Shanghai SSE Composite, Nifty 50, Nikkei 225, BSE Sensex, and Ibovespa.
