S&P/ASX Indices Rebalance: September 2026

Five New Additions to Flagship S&P/ASX 200

Elsight, Smartgroup Crop, Sunrise Energy Metals, Service Stream and Weebit Nano were added to the S&P/ASX 200 after their three-month average FMC at the rebalance reference date exceeded the 179-rank buffer for selection.  Conversely, security price depreciation resulted in Pantoro Gold and Tuas falling below the 221-rank buffer.  Meanwhile EVT, GrainCorp and GQG Partners were dropped despite not falling below the buffer, as three higher-ranked companies exceeded the 179 rank entry threshold.

All newly added companies also met other eligibility criteria, which are also data points in the S&P/ASX Stock Selection Data Product, such as liquidity and a minimum free float factor, and were not suspended from trading or involved in corporate actions such as an acquisition. 

New Additions to S&P/ASX 50 and S&P/ASX 100  

Mineral Resources and NEXTDC were added to the S&P/ASX 50, while Codan was added to the S&P/ASX 100. Mineral Resources and NEXTDC were added to satisfy the constituent count of the S&P/ASX 50 after Wisetech and Cochlear fell below the 61^st rank buffer.  Meanwhile Codan exceeded the 84^th rank buffer for the S&P/ASX 100, while Atlas Arteria dropped out after falling below the 116^th rank buffer.
