Jakarta.  Indonesia’s benchmark index ended lower on Tuesday as investors turned cautious ahead of a major Morgan Stanley Capital International free-float adjustment and key global policy meetings, with sentiment also pressured by mixed movements across Asian markets.

The Jakarta Composite Index (JCI) fell 24.52 points, or 0.30 percent, to 8,092 at Tuesday’s close, after moving within the 8,039–8,151 range throughout the day.

Trading volume reached 30.1 million shares, worth Rp 19.7 trillion ($1.2 billion), across 2.3 million transactions. A total of 341 stocks advanced, 309 declined, and 159 remained unchanged.

According to Pilarmas Investindo Sekuritas, today’s decline was driven by a “double blow” from both internal and external factors.

From the domestic side, the JCI was weighed down by investor caution ahead of the upcoming MSCI free-float adjustment, which could alter the weighting of certain corporate group stocks within the index.

“This potential adjustment may limit some corporate groups’ chances of inclusion, or even lead to their removal or reduced weighting,” Pilarmas wrote in its research note on Tuesday.

Externally, investors were awaiting key global events this week, particularly the US Federal Reserve’s policy meeting, which is widely expected to deliver a 25-basis-point rate cut following a softer September inflation report. Markets are also seeking clarity on potential further rate cuts in December and any signal of tapering quantitative tightening.

Adding to the global watchlist, US President Donald Trump is set to meet Chinese President Xi Jinping on the sidelines of a Pacific Rim summit in South Korea, raising hopes of renewed trade talks that could ease long-running tensions between the two economies.

Across Asia, regional markets also turned mixed. Hong Kong’s Hang Seng fell 0.6 percent to 26,276.18, reversing earlier gains, while Shanghai’s Composite Index slipped 0.2 percent to 3,988.68 after briefly breaching the 4,000 level, its highest in a decade. Japan’s Nikkei 225 dropped 0.6 percent to 50,219.18, while South Korea’s Kospi shed 0.8 percent to 4,010.41.

On Wall Street, all three major indices hit new highs on Monday ahead of this week’s events. The S&P 500 rose 1.2 percent to 6,875.16, the Dow Jones Industrial Average climbed 0.7 percent to 47,544.59, and the Nasdaq Composite jumped 1.9 percent to 23,637.46.

Among top gainers in the IDX were Gaya Abadi Sempurna (SLIS), up 33.8 percent; Era Mandiri Cemerlang (IKAN), up 25.7 percent; Sunson Textile Manufacturer (SSTM), up 25 percent; and Soho Global Health (SOHO), up 24.7 percent.

Top decliners included Sarana Mitra Luas (SMIL), which tumbled 14.9 percent; Dwi Guna Laksana (DWGL), down 14.7 percent; Ateliers Mecaniques D’Indonesie (AMIN), down 14.49 percent; and Buana Listya Tama (BULL), which slid 14.4 percent.
