JAKARTA – A significant development on the Indonesia Stock Exchange (IDX) sees shares of PT Bumi Resources Tbk (BUMI) making a triple entry into key indices following the latest rebalancing exercise. This strategic move highlights BUMI’s growing influence in the Indonesian stock market.
According to the official announcement from the IDX, the issuer, a prominent collaboration between the Bakrie Group and Salim Group, will see its shares integrated into the prestigious LQ45, IDX80, and Bisnis-27 indices. This significant inclusion is set to take effect from November 3, 2025, and will remain until January 30, 2026.
For the highly liquid LQ45 index, BUMI’s shares will command a respectable weight of 0.73% within the index, supported by a free float ratio of 29.19%. Alongside BUMI, other new constituents welcomed into the LQ45 index include DSSA, EMTK, HEAL, and NCKL, signaling a refreshed composition for this key benchmark. Conversely, several prominent stocks are being removed from this premier, most liquid index. These include ARTO, BRIS, JSMR, MAPA, and SMRA, making way for the new additions.
Moving to the IDX80 index, BUMI’s shares will secure a 0.71% weighting, reflecting its growing market presence. The IDX80 also welcomes a broader range of new constituents alongside BUMI, namely DSSA, KIJA, KPIG, PNBN, RATU, and WIFI, further diversifying its composition. However, a number of existing components are being delisted from the IDX80. These include AUTO, BFIN, BNGA, BRIS, MNCN, SRTG, and TKIM, as the index adjusts to market dynamics.
Finally, in the Bisnis-27 index, BUMI’s shares achieve their highest weighting among the three, at 1.14%. This index also sees a substantial influx of new members. Besides BUMI, new additions to the Bisnis-27 index comprise ADMR, ADRO, INCO, INDF, JPFA, MEDC, NCKL, and PGEO, further broadening its sector representation. Consequently, the Bisnis-27 index will bid farewell to several constituents, including AKRA, BRIS, CPIN, CTRA, ICBP, ISAT, PGAS, and SCMA, as the index recalibrates its focus.
Notably, in a contrasting turn of events to BUMI’s strong performance, BRIS shares face a significant setback, being simultaneously removed from all three major indices: LQ45, IDX80, and Bisnis-27. This highlights the dynamic and competitive nature of index rebalancing on the Indonesian stock market.
