JAKARTA – The Indonesian stock market demonstrated a solid performance during the trading week of May 4–8, 2026. While transaction activity surged significantly across the board, the Jakarta Composite Index (JCI) remained just shy of the psychological threshold of 7,000.
Data released by the Indonesia Stock Exchange (IDX) reveals a notable spike in market participation. The average daily trading volume jumped by 23.57 percent, reaching 45.86 billion shares compared to 37.11 billion the previous week. This growth in volume was accompanied by a 26.14 percent rise in the average daily transaction value, which climbed to IDR 23.06 trillion from IDR 18.27 trillion. Additionally, the daily transaction frequency grew by 9 percent, recording 2.55 million trades versus 2.34 million in the prior week.
Despite the heightened activity, the JCI saw a modest gain of 0.18 percent, closing at 6,969.396, up from 6,956.804 the previous week. Correspondingly, the market capitalization of the IDX edged up by 0.19 percent to a total of IDR 12,406 trillion, compared to IDR 12,382 trillion previously.
Investor sentiment presented a nuanced picture. While foreign investors logged a net buy of IDR 11.42 trillion by the end of the week, the cumulative data for 2026 still shows a net foreign sell-off totaling IDR 37.61 trillion.
The Financial Services Authority (OJK) noted that the domestic capital market is showing signs of recovery following a period of pressure earlier in the year. OJK Chair Friderica Widyasari Dewi highlighted that market dynamics have been heavily influenced by rising global uncertainty. Speaking at the Financial System Stability Committee conference in Jakarta on May 7, 2026, she emphasized that the domestic market moved dynamically throughout the first quarter amid these global headwinds.
Reviewing the first quarter of 2026, the JCI stood at 7,048.22 on March 31. While this represented an 18.49 percent correction from previous peaks, it still reflected a year-on-year growth of 8.26 percent. As the market entered May 2026, a clearer upward trend emerged.
Reflecting on this recovery, Dewi noted that the index began showing consistent strength at the start of the month. By May 5, 2026, the JCI reached 7,057.11, marking a month-to-date appreciation of 1.44 percent, signaling a resilient outlook as investors navigate the ongoing global economic landscape.
