January 1980, the All Ordinaries (colloquially, the "All Ords"; also known as the All Ordinaries Index, AOI) is the oldest index of shares in Australia, so called because it contains nearly all ordinary (or common) shares listed on the Australian Securities Exchange (ASX). The market capitalization of the companies included in the All Ords index amounts to over 95% of the value of all shares listed on the ASX. The 3-letter exchange ticker in Australia for the All Ordinaries is "XAO".

When established, the All Ords had a base index of 500; this means that if the index is currently at 5000 points, the value of stocks in the All Ords has increased tenfold since January 1980, not factoring in inflation.

On 3 April 2000, the All Ords was restructured to consist of the 500 largest companies by market capitalisation.^[1] This coincided with the introduction of new benchmark indices such as the S&P/ASX 200. The importance of the All Ords has been significantly lessened by the introduction of these new indices.

• On 1 November 2007, the index was at 6873.20, its highest value.
• As of 22 January 2008, it had fallen to 5,222.0 points due to turmoil related to the US 2007 subprime mortgage financial crisis, a 24 percent fall.
• On 6 March 2009, it was at a low of 3,111.7 points, in the wake of a worldwide drop in stock values, 54% less than the 1 November 2007 high.
• As of 14 September 2009, the index has rebounded to 4,568.5 points, representing a 46.8 percent increase from the 6 March 2009 low.
• On 5 August 2011, the index fell to 4159 points, with a 4.6% fall in one day, the biggest fall since the subprime mortgage crisis.
