The Indonesia Stock Exchange (IDX) has implemented changes to its Composite Index composition at the start of the new month, with several stocks excluded from the benchmark indicator. The move is part of the exchange's regular review process to ensure the index accurately reflects market performance and maintains appropriate listing standards.

The IDX periodically reassesses stocks included in its primary index based on established criteria including liquidity, market capitalization, and trading activity. Companies that fail to meet these benchmarks may be removed to preserve the integrity and representativeness of the index for investors and market participants.

These periodic adjustments are standard practice among major stock exchanges globally and serve to keep benchmark indices responsive to changing market conditions. The Composite Index remains Indonesia's most widely tracked equity gauge and is closely monitored by domestic and international investors seeking exposure to Indonesian equities.

Market participants are advised to review official IDX announcements for complete details regarding which stocks were affected by the latest index review and the effective dates of any changes.
