Expanded FBM KLCI Set to Reshape Stock-Level Flows Without Broad Disruption

Kuala Lumpur, 21 September 2026 – The expansion of the FBM KLCI from 30 to 50 constituents is expected to reshape liquidity and sector exposure at the individual-stock level without causing a broad market disruption. The change will be phased, with the 20 additional constituents entering at half of their eventual index weights in December 2026 before moving to full weights in June 2027.
