Indonesia’s Jakarta Composite closed Oct. 20 up 5.65% at 5,278.89, rebounding from two steep declines as the country’s stock exchange prepared to change which shares count toward the benchmark. The close was about 4 a.m. ET (8 a.m. UTC). The index had fallen 11.57% on Oct. 16 and 3.64% on Oct. 19. The Indonesia Stock Exchange plans to exclude 80 shares with highly concentrated ownership from the index calculation. Together, they account for about 18% of the benchmark’s weight. The shares would remain listed and tradable, and the exchange has not set a date for the change. The plan follows MSCI’s [proposal to change Indonesia’s market classification]() from emerging-market to standalone-market status. MSCI raised concerns about opaque ownership and suspected coordinated trading. It also said announced reforms had yet to produce consistent results across the equity market. The reclassification remains a proposal. Feedback on MSCI’s proposal is due April 30, 2027. MSCI plans to decide by June 30, 2027. ## Links in this article - [proposal to change Indonesia’s market classification](https://www.tokenpost.com/news/investing/33106)
