The IDX Composite closed higher on Monday, November 2, 2026, as Indonesian equities recovered from an early decline and investors assessed a significant change to the benchmark's composition. The index finished at 5,096.83, up 39.78 points, or 0.79 percent, from the previous session's 5,057.05 close, according to Kontan.
Index reform takes effect
Monday was the first trading session under the Indonesia Stock Exchange's revised treatment of stocks with high shareholding concentration. The exchange removed those securities from the IDX Composite calculation, although the shares remain listed and tradable. The Jakarta Post reported that the weights of the excluded stocks would be redistributed among the remaining constituents.
The change followed concerns about market quality and benchmark representativeness. It is important for investors to distinguish the methodology adjustment from a delisting: the affected companies continue to trade, but their price movements no longer directly influence the benchmark under the revised rules. The exchange had also indicated that the adjustment would not mechanically change the index's reference level.
Early weakness gives way to recovery
The index opened 0.35 percent lower at 5,039.54 before rebounding during the second trading session, according to the Jakarta Post. By the close, the benchmark had recovered beyond its opening level. The move represented a reversal from the previous session, when the index fell 0.80 percent to 5,057.05 after testing levels below 5,000.
Raw materials lead sector gains
Sector performance was mixed but tilted positive. Raw materials rose 2.12 percent, the strongest gain among the sectors reported by Kontan. Energy advanced 1.53 percent, infrastructure gained 1.40 percent and industrials increased 0.76 percent. Financials rose 0.36 percent, while non-primary and primary consumer goods posted smaller gains of 0.30 percent and 0.04 percent, respectively.
Health care was the weakest sector, falling 0.64 percent. Property and real estate declined 0.22 percent, technology slipped 0.16 percent, and transportation and logistics fell 0.12 percent. Market breadth remained positive, with 315 stocks advancing, 285 declining and 118 unchanged. Trading volume reached 35.31 billion shares, with transaction value of IDR 12.38 trillion.
For further coverage of the IDX Composite, investors should continue to separate movements caused by the new index methodology from ordinary changes in constituent prices.
