Jakarta. Jakarta Composite Index (JCI) closed in positive territory on Wednesday, rising 97 points, or 1.19%, to 8,310 after trading within a range of 8,227–8,310.

Trading activity remained solid, with volume reaching 51.77 billion shares and turnover totaling Rp 23.54 trillion ($1.39 billion) across more than 3.18 million transactions. Advancers outnumbered decliners, with 454 stocks rising, 216 falling, and 145 unchanged.

On the gainers board, Astrindo Nusantara Infrastruktur (BIPI) jumped 34.52%, Cipta Perdana Lancar (PART) surged 34.33%, while Trimitra Prawara Goldland (ATAP) and Multi Garam Utama (FOLK) each climbed 25%.

Pilarmas Investindo Sekuritas said the JCI moved in line with stronger Asian equities during the Lunar New Year holiday period, supported by easing tensions between the United States and Iran as well as progress in Russia–Ukraine peace negotiations.

According to Pilarmas, signs of understanding between Washington and Tehran could reduce geopolitical risk premiums. Iran’s Foreign Minister Abbas Araqchi indicated both sides had reached preliminary common ground, with further talks expected in Geneva within two weeks under a new proposal.

“The market is also monitoring US-mediated Ukraine–Russia negotiations in Geneva, where President Donald Trump is urging Kyiv to reach an agreement to end the four-year conflict,” Pilarmas wrote in its Wednesday research note.

From Japan, Pilarmas highlighted strong export growth, with shipments rising 16.8% year on year in January — the fastest expansion in nearly four years — driven by demand from Asia and Western Europe.

Domestically, investors are awaiting the outcome of a key bilateral meeting between Indonesia and the United States, where both presidents are scheduled to discuss relations and strategic economic cooperation, including potential trade agreements. Pilarmas said the talks are expected to help ease tariff tensions and strengthen Indonesia’s position in the U.S. market.

Across the region, Asian shares were broadly higher on Wednesday. Japan’s Nikkei 225 gained 1.2% to 57,249.43 by midday, led by technology stocks such as Tokyo Electron, which rose 3.5%, while several regional markets remained closed for Lunar New Year holidays.
