Jakarta. After days of pressure linked to MSCI-related concerns, the Jakarta Composite Index finally returned to positive territory on Tuesday, surging 199.87 points, or 2.52%, to close at 8,122 as investors cheered constructive signals from regulators and a calmer policy outlook.

Total transaction value reached Rp 28.71 trillion ($1.71 billion), with market breadth firmly positive. 677 stocks advanced, 121 declined, and 160 were unchanged. Trading volume stood at 57.09 billion shares across 3.19 million transactions.

On the gainers’ board, Langgeng Makmur Industri (LMPI) soared 35%, Humpuss Maritim Internasional (HUMI) jumped 34.08%, Eka Sari Lorena Transport (LRNA) climbed 34.04%, and Logindo Samudramakmur (LEAD) advanced 26.98%.

Meanwhile, Nusantara Sawit Sejahtera (NSSS) slid 14.9%, Mora Telematika Indonesia (MORA) fell 14.86%, MD Entertainment (FILM) dropped 14.81%, and Inter-Delta (INTD) sank 14.74%.

Pilarmas Investindo Sekuritas said the rebound was driven by positive sentiment from regulators, supported by domestic and global macroeconomic data. The index, which opened lower, moved back into the green as markets responded favorably to steps aimed at stabilizing trading.

Confidence improved after a constructive discussion involving the Financial Services Authority (OJK), the Indonesia Stock Exchange (IDX), and MSCI. “MSCI guided index methodology and calculation, and the discussion will continue at the technical stage. This is a positive signal and raises hopes for better management of the domestic capital market,” Pilarmas wrote in its research note.

The JCI’s rally tracked gains across Asian markets. Sentiment was lifted by news of an agreement between the United States and India, under which US President Donald Trump cut import tariffs on Indian goods to 18% from 25%. Pilarmas added that upbeat US economic data also helped support risk appetite.

In the region, Japan’s Nikkei 225 jumped 3.9% to 54,720.66, its highest close on record, led by technology stocks. Disco Corp. rose 7.4%, while Advantest gained 7.1%. Optimism was further supported by expectations that Prime Minister Sanae Takaichi’s Liberal Democratic Party will secure a strong majority in the Feb. 8 election, though some analysts cautioned that increased fiscal spending could weaken the yen.

South Korea’s Kospi surged 6.8% to 5,288, also a record, as confidence returned to AI-linked stocks. Samsung Electronics jumped 11.4%, while SK Hynix rocketed 9.3%.

Elsewhere, Hong Kong’s Hang Seng edged up 0.2% to 26,834, and China’s Shanghai Composite rose 1.3% to 4,067.
