Like every index it owns nothing: it is a number produced by applying a published weighting formula to a selected list of companies, revised on a schedule the provider sets. ## What this index covers The S&P/ASX All Technology Index covers technology sector companies listed on the Australian Securities Exchange, within the Australia market. S&P Dow Jones Indices/ASX defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number. The index name does not state a fixed company count, so the number of constituents follows the eligibility rules rather than a target. ## How constituents are weighted Weighted by FMC, subject to a single constituent weight cap of 10% of the total index weight. The weighting method is the single biggest driver of how an index behaves. Two indexes covering the same market can diverge for years purely because they weight differently, which is why comparing index levels without knowing the method tells you very little. ## What qualifies for inclusion A three-month average FMC of at least AUD 120 million (AUD 80 million for current members), Relative Liquidity of at least 30%, and a three-month median daily value traded of at least AUD 0.25 million (AUD 0.175 million for members). It must be in the GICS Information Technology sector or selected sub-industries such as payment processing and interactive media. Eligibility rules are the part of an index most readers never look at and the part that decides what it can possibly measure. A screen that excludes a whole sector, or admits only one listing venue, shapes the result far more than any day of trading does. ## How long a listing must exist first A newly public IPO or direct listing with at least AUD 300 million of FMC on its first trading day can be fast tracked in, with five business days of notice, without meeting the liquidity requirement. A seasoning rule is why a large new listing does not appear in an index the week it starts trading. It is a deliberate lag, and it means an index can under-represent a fast-growing part of the market for months at a time. ## When the membership is revised Rebalanced quarterly, effective after the close on the third Friday of March, June, September and December. A spin-off enters at a zero price and is reviewed for ongoing inclusion at the next quarterly rebalancing. Reconstitution is the one date an index changes shape by design rather than by price. Funds tracking it have to trade toward the new membership, which is why the schedule matters to anyone holding the tracker rather than only to the provider. ## The rule that surprises people The index mixes a GICS sector with named sub-industries from other sectors, so it can hold companies, such as payment processors, interactive media and consumer electronics firms, that sit outside Information Technology. ## References - [S&P Dow Jones Indices/ASX: S&P Dow Jones Indices, S&P/ASX Australian Indices Methodology](https://www.spglobal.com/spdji/en/documents/methodologies/methodology-sp-asx-australian-indices.pdf), as published 2025.
