IDX Reshuffles LQ45, IDX30, IDX80 Constituents

The Indonesia Stock Exchange (IDX) has reshuffled the constituent lists for several main stock indices, namely the LQ45, IDX30, and IDX80, in a major evaluation that will take effect from 3 August to 30 October 2026. For the LQ45 index, the IDX has included two new stocks: PT Indika Energy Tbk. (INDY) and PT Trimegah Bangun Persada Tbk. (NCKL). Both replace PT Semen Indonesia (Persero) Tbk. (SMGR) and PT Sarana Menara Nusantara Tbk. (TOWR), which have been removed from the index comprising the 45 most liquid stocks. Meanwhile, changes to the IDX30 involved only one constituent swap. PT Darma Henwa Tbk. (DEWA) officially enters the index, replacing PT Bukit Asam Tbk. (PTBA). For the IDX80, the IDX added three new issuers: PT BFI Finance Indonesia Tbk. (BFIN), PT Perkebunan London Sumatra Indonesia Tbk. (LSIP), and PT Trimegah Bangun Persada Tbk. (NCKL). These three replace PT Indocement Tunggal Prakarsa Tbk. (INTP), PT Pantai Indah Kapuk Dua Tbk. (PANI), and PT Industri Jamu dan Farmasi Sido Muncul Tbk. (SIDO), which are exiting the index. In addition to changing constituents, the IDX also adjusted the number of shares used in index calculations and the weighting of each issuer according to the periodic evaluation results. This major evaluation of the indices is carried out regularly to ensure constituents continue to represent stocks with high liquidity, large market capitalisation, and compliance with applicable free float regulations. The new composition will serve as a reference for market participants, including investment managers who manage index mutual fund products and exchange traded funds (ETFs). In terms of performance, all three indices have still recorded a weakening since the start of the year. As of the close of trading on Monday (27/7/2026), the Jakarta Composite Index (IHSG) stood at 6,185.783, down 28.46% year-to-date (YtD). The LQ45 corrected 27.64% to 612.558, the IDX30 weakened 21.12% to 344.884, whilst the IDX80 suffered the deepest decline, falling 30.53% YtD to 92.085.
