JAKARTA — MSCI Inc. officially unveiled its May 2026 index review for the MSCI Equity Indexes on Tuesday, May 12, 2026. The latest announcement signals a significant shift for the Indonesian capital market, with six major domestic issuers removed from the prestigious MSCI Global Standard Index.
According to the official announcement, these index adjustments are scheduled to take effect at the close of trading on May 29, 2026, and will be fully implemented by June 1, 2026.
In this particular review cycle, MSCI did not add any new Indonesian companies to the Global Standard Index. Instead, the index provider opted for a clean sweep of six local stocks, namely AMMN, BREN, TPIA, DSSA, CUAN, and AMRT.
Despite its removal from the Global Standard Index, AMRT has transitioned into the MSCI Small Cap Index. This move reflects ongoing portfolio rebalancing as investors keep a close watch on market volatility, which some analysts view as an opportunity for a “buy on dip” strategy as foreign investors begin to accumulate blue-chip stocks.
The restructuring also extended to the MSCI Small Cap Index, where MSCI delisted 13 Indonesian companies. The firms removed from this index include ANTM, AALI, BANK, BSDE, DSNG, SIDO, MIDI, MIKA, MSIN, TKIM, APIC, SSMS, and TAPG.
On a global scale, MSCI reported the addition of 49 stocks and the removal of 101 companies from the MSCI ACWI Index during the May 2026 review. The most significant additions to the MSCI Emerging Markets Index, ranked by total market capitalization, were Brazil’s Itau Unibanco, along with China’s Yangtze Optical Fibre and Cable Joint Stock Limited Company and Sichuan Biokin Pharmaceutical.
Looking ahead, MSCI has confirmed that the next index review will be announced on August 12, 2026, with changes becoming effective on September 1, 2026.
Summary of MSCI Index Changes for Indonesian Issuers:
| Index | Additions | Deletions |
|---|---|---|
| MSCI Global Standard Indexes | – | AMMN, BREN, TPIA, DSSA, CUAN, AMRT |
| MSCI Small Cap Indexes | AMRT | ANTM, AALI, BANK, BSDE, DSNG, SIDO, MIDI, MIKA, MSIN, TKIM, APIC, SSMS, TAPG |
