ASX Index Shake-Up: Key Changes to the S&P/ASX 200 and Beyond
The Australian Securities Exchange (ASX) is set to see a significant reshuffle of its benchmark indices, with S&P Dow Jones Indices announcing a raft of changes that will take effect prior to the market opening on Monday, March 23rd. These regular quarterly reviews ensure that the indices accurately reflect the prevailing market conditions and the performance of Australian listed companies. This latest update sees several notable companies departing the S&P/ASX 200, while new entrants are poised to join, alongside adjustments to other prominent indices.
S&P/ASX 200: Departures and Newcomers
The most prominent changes involve the S&P/ASX 200 index, the benchmark for the Australian equity market. Three companies will be removed from this influential index, a consequence of their share prices falling below the required thresholds for inclusion.
Catapult Sports Ltd (ASX: CAT): This sports technology firm is one of the companies being delisted from the S&P/ASX 200. Over the past six months, Catapult’s share price has experienced a significant decline, shedding nearly 40%. This downturn has resulted in a market capitalisation of approximately $1.23 billion.
DigiCo Infrastructure REIT (ASX: DGT): The data centre operator is also being ejected from the index. Its share price has suffered a substantial 50% drop over the last year, bringing its market capitalisation down to around $1.12 billion.
EBOS Group Ltd (ASX: EBO): This New Zealand-based pharmacy wholesaler is also making way. While its shares have fallen by almost 44% in the past 12 months, its exit might be more influenced by relative liquidity – the ease with which its shares can be traded – rather than solely its market capitalisation.
These companies are being replaced by three new entrants that have demonstrated strong performance and market presence:
Predictive Discovery Ltd (ASX: PDI): This gold miner is set to join the S&P/ASX 200. Predictive Discovery has seen an impressive surge in its share price, climbing 185% over the last 12 months. This remarkable growth has propelled its market capitalisation to $2.41 billion.
SRG Global Ltd (ASX: SRG): As an engineering and construction services provider, SRG Global has also earned its place in the index. Its shares have risen by a substantial 120%, reflecting a market capitalisation of $1.7 billion.
Vulcan Energy Resources Ltd (ASX: VUL): The lithium developer rounds out the new additions. While its share price has seen a more modest gain of 11% in the past year, it boasts a market capitalisation of $1.73 billion and a significantly strengthened balance sheet compared to a year ago, indicating a robust financial position.
Broader Index Adjustments
Beyond the S&P/ASX 200, other significant Australian indices are also undergoing changes:

These regular index rebalances are a crucial mechanism for maintaining the integrity and representativeness of the ASX indices, providing investors with accurate benchmarks for performance and investment strategies. The changes highlight the dynamic nature of the Australian stock market, with companies’ fortunes fluctuating based on performance, market sentiment, and broader economic factors. Investors will be watching closely to see how these shifts impact index-tracking funds and the broader investment landscape.
