JCI Strengthens by 1.11%, Energy Stocks Act as Main Drivers of Trading
The Indonesia Composite Index (JCI) on the Indonesia Stock Exchange (IDX) successfully closed in the green during Tuesday afternoon trading. The index’s strengthening was primarily supported by the positive performance of stocks in the energy sector, which led the market gains.
The JCI ended the trading session with an increase of 68.04 points, or 1.11%, to the level of 6,195.42. Meanwhile, the LQ45 index, which comprises 45 blue-chip stocks, also strengthened by 8.10 points, or 1.33%, to 619.27.
“The JCI strengthened as market participants digested economic data,” stated Maximilianus Nico Demus, Associate Director of Research and Investment at Pilarmas Investindo Sekuritas, in his analysis in Jakarta on Tuesday.
In the global market, investors continue to closely monitor the progress of negotiations between the United States and Iran, which remains shrouded in uncertainty. This condition has also triggered fluctuations in global crude oil prices. Geopolitical instability remains a key concern following reports that Tehran has temporarily suspended talks with Washington in response to Israeli attacks in Lebanon. Conversely, US President Donald Trump has asserted that the negotiation process is still ongoing. Market attention is also focused on the conflicting statements from US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu regarding recent discussions on the conflict in Lebanon.
Domestically, positive sentiment was driven by the latest economic data. S&P Global reported that Indonesia’s Purchasing Managers’ Index (PMI) increased from 49.1 in April 2026 to 50.0 in May 2026, reflecting the resilience of the domestic sector amidst global pressures affecting export activities. Furthermore, the Central Bureau of Statistics (BPS) recorded May 2026 inflation at 0.28% month-on-month and 3.08% year-on-year, figures that remain within Bank Indonesia’s target range of 2.5% plus/minus 1%.
BPS also reported that Indonesia’s trade balance maintained a surplus of US$90 million, driven by export values of US$25.30 billion against imports of US$25.31 billion. Based on the IDX-IC Sectoral Index, five sectors recorded gains, with the energy sector leading with a 1.78% increase, followed by infrastructure at 0.64% and basic materials at 0.58%. Conversely, six sectors weakened, with the transportation and logistics sector recording the deepest decline of 3.20%, followed by healthcare at 2.65% and property at 1.13%.
