Jakarta. Jakarta Composite Index (JCI) closed higher at 8,131 on Tuesday, rising 99.86 points, or 1.24%, after trading within a range of 8,011 to 8,131.

Market activity showed strong participation, with total volume reaching 45.81 billion shares and turnover recorded at Rp 20.37 trillion ($1.21 billion) across more than 2.45 million transactions. Gainers outnumbered decliners, with 556 stocks advancing, 144 falling, and 116 unchanged.

On the winners’ board, Vastland Indonesia surged 34.65%, while MNC Studio, Lotter Chemical, and Nusantara Almazia each jumped 25%.

Meanwhile, Mega Perintis dropped 10.34%, Grand House slid 9.89%, Trisula Textile slipped 9.85%, and both Prima Globalindo and Soraya Berjaya declined 9.84%.

Pilarmas Investindo Sekuritas said the JCI strengthened as investors continued to monitor developments in Indonesia’s domestic capital market reform process. The firm highlighted a follow-up technical meeting scheduled for Feb. 11, 2026, between officials from the Financial Services Authority (OJK), the Indonesia Stock Exchange (IDX), and MSCI to present an accelerated market integrity action plan targeted for completion before the end of April 2026.

“This provides a clear signal of regulators’ commitment to capital market reform, which should strengthen global institutional investor confidence and be supported by conglomerate-listed companies,” Pilarmas wrote in a research note on Tuesday.

The brokerage added that the JCI also tracked gains across Asian and US equities, although investors remained cautious about geopolitical developments in the Middle East amid hopes for peace involving the United States. Israeli Prime Minister Benjamin Netanyahu is scheduled to meet U.S. President Donald Trump in Washington this week to discuss Iran-related negotiations and broader regional security issues.

“Strategic risks in the Middle East have therefore not fully disappeared,” Pilarmas said.

Asian markets were mostly higher Tuesday, led by Japan after a historic election victory for the country’s first female prime minister, Sanae Takaichi. Japan’s Nikkei 225 jumped 2.3% to 57,650 in afternoon trading, following a 3.9% surge to a record high on Monday after her party’s landslide parliamentary win. Investors expect reforms and stimulus measures that will not overly burden Japan’s public finances.

Elsewhere, South Korea’s Kospi edged up less than 0.1% to 5,301.69, Hong Kong’s Hang Seng rose 0.5% to 27,163, and the Shanghai Composite gained nearly 0.2% to 4,130.

On Wall Street, U.S. stocks were coming off their best session since May at the end of last week, though concerns linger that valuations may have become too stretched after record-setting rallies. The S&P 500 climbed 0.5% to 6,964, the Dow Jones Industrial Average edged up less than 0.1% to 50,135, and the Nasdaq Composite advanced 0.9% to 23,238.

A persistent concern for investors is whether massive spending by Big Tech and other companies on artificial intelligence will generate sufficient profits to justify the scale of those investments.
