Jakarta. Indonesian stocks kicked off the first trading day of December with mild optimism as the Jakarta Composite Index (JCI) opened higher on Monday.

The benchmark index began the session at 8,541, climbing 33 points (0.39 percent) within minutes and moving in a narrow range of 8,517–8,553.

In the first 10 minutes, early trading showed 4.87 billion shares exchanged with a Rp 2.71 trillion turnover ($162.63 million), spread across more than 315,000 transactions. 260 stocks gained, 266 fell, while 180 were unchanged.

Pilarmas Investindo Sekuritas said sentiment remains cautious as China’s latest PMI readings reinforced concerns about slowing momentum in Asia’s largest economy. China’s manufacturing PMI edged up slightly from 49.0 to 49.2, remaining below the expansion line for the eighth straight month, while its non-manufacturing PMI slipped to 49.5 amid persistent weakness in real estate and services. The composite PMI dipped to 49.7, signaling a return to contraction despite Beijing’s USD 141 billion stimulus since late September.

From the US, markets enter a critical week as a batch of December indicators, including ISM manufacturing and services, PPI, and the Fed’s preferred inflation gauge, PCE, will set the tone ahead of next week’s FOMC meeting. Rising jobless claims are expected to show further cooling in the labor market. European markets are also watching incoming inflation and PPI data ahead of the region’s Q3 GDP release.

Domestically, Pilarmas noted December’s historically strong pattern for the JCI, raising hopes for a move toward its 8,660 target. The broker also flagged ongoing government discussions on 2026 automotive incentives, with policymakers considering reduced EV subsidies as the sector matures. While this could pressure EV-focused issuers in the near term, traditional automakers and companies with strong local manufacturing footprints may benefit as the government pushes for higher domestic content and deeper supply-chain capacity.

On Wall Street, equities closed November on a cautiously positive note.

The S&P 500 rose 0.5 percent, the Dow Jones gained 289 points (0.6 percent), and the Nasdaq added 0.7 percent, though it still ended the month down 1.5 percent. Market sentiment improved as traders priced in an 87 percent probability of another Fed rate cut at the December 10 meeting, balancing concerns over softening labor data and mixed economic readings.

Elsewhere in Asia, Japan’s Nikkei opened up 65 points (0.13 percent) at 50,318 before easing. South Korea’s Kospi gained 41 points (1.03 percent) to 3,967, Hong Kong’s Hang Seng climbed 87 points (0.34 percent) to 25,945, and China’s SSE added 6 points (0.15 percent) to 3,894.

Back in Jakarta, the Indonesia Stock Exchange (IDX) flagged Unusual Market Activity (UMA) in four stocks: Red Planet Indonesia (PSKT), Intraco Penta (INTA), Sawit Sumbermas Sarana (SSMS), and Surya Fajar Capital (SFAN). PSKT surged 94.16 percent over the past month, INTA jumped 76.19 percent, SSMS eased 0.93 percent, and SFAN rose 0.78 percent.

IDX also suspended trading in Intan Baru Prana (IBFN) and Personel Alih Daya (PADA) due to significant cumulative price increases, IBFN skyrocketed 134.69 percent in a month, and PADA doubled.

Meanwhile, suspensions were lifted for Raharja Energi Cepu (RATU) and Mora Telematika Indonesia (MORA), allowing investors to resume trading on both counters starting today’s first session.
