Indonesia Plans to Remove 80 Concentrated Stocks from Main Benchmark

Jakarta, 20 October 2026 – The Indonesia Stock Exchange plans to exclude 80 companies with highly concentrated shareholder structures from the Jakarta Composite Index, according to exchange president director Jeffrey Hendrik. The affected stocks account for about 18% of the benchmark’s weight. They will remain listed and tradable, but their removal is intended to make the index a more accurate measure of market movement.

For Indonesian and regional investors, the change matters because benchmarks guide passive funds, performance comparisons and sentiment. The confirmed proposal concerns index membership, not delisting or a ban on trading. Analysis that it will improve market quality depends on implementation and methodology. Exclusion may reduce benchmark distortion, but it can also trigger mechanical selling and short-term volatility as funds rebalance.
