JAKARTA, Investortrust.id — The Indonesia Stock Exchange has reshuffled the LQ45, IDX30, and IDX80 indices on Monday, Jan 26, 2026 in Jakarta to reflect changes in liquidity and market capitalization, a move that brings BREN into both LQ45 and IDX80 and highlights the growing presence of stocks linked to Prajogo Pangestu. The revised index composition is expected to influence portfolio allocation and trading activity.
The exchange said the new index constituents will take effect from Feb 2, 2026 and remain valid until April 30, 2026. The rebalancing was part of the regular review to ensure index representation stays aligned with market conditions.
Under the latest changes, BUMI and EMTK were added to the IDX30 index, while ITMG and SMGR were removed. The update reflects shifts in liquidity and capitalization among large cap stocks.
For the LQ45 index, BREN was included to replace ACES, which was dropped from the list. As a result, two Prajogo Pangestu related stocks, BRPT and BREN, are now constituents of the LQ45 index.
The IDX80 index also saw changes with the addition of BREN, CUAN, and HRTA. Meanwhile, AVIA, LSIP, and PNBN were removed from the index.
LQ45 is an index comprising 45 selected stocks based on high liquidity and large market capitalization. The index also considers strong fundamentals and growth prospects in its selection criteria.
IDX30 measures the price performance of 30 stocks with high liquidity and large market capitalization supported by solid fundamentals. IDX80 tracks the performance of 80 stocks with similar liquidity and capitalization characteristics, offering a broader market representation.
