The Jakarta Composite Index (IHSG) concluded the trading week of May 4-8, 2026, with a notable gain, signaling a positive shift from the previous period. Data released by the Indonesia Stock Exchange (IDX) confirmed this upward momentum, showing a 0.18 percent increase in the index over the week.
Closing at 6,969.3, the IHSG demonstrated a modest but significant rise from its previous week’s close of 6,956.8. This positive performance of the benchmark index was closely paralleled by an expansion in the overall market capitalization of the Indonesia Stock Exchange, reflecting broader investor confidence.
Indeed, the IDX’s market capitalization saw a 0.19 percent increase, reaching IDR 12,406 trillion from IDR 12,382 trillion recorded in the preceding week, as stated in an official announcement from the IDX on Saturday, May 9, 2026.
Beyond the index’s climb, the week also witnessed a surge across various trading metrics. Average daily transaction frequency, value, and volume all experienced growth compared to the previous week. The most substantial leap was observed in the average daily transaction volume on the IDX, which surged by an impressive 23.57 percent, reaching 45.86 billion shares, up from 37.11 billion shares.
Concurrently, the average daily transaction value escalated significantly by 26.14 percent, climbing to IDR 23.06 trillion from IDR 18.27 trillion. Furthermore, the IHSG’s average daily transaction frequency registered a 9 percent uptick, expanding from 2.34 million transactions to 2.55 million transactions this week.
On the foreign investment front, Friday, May 8, 2026, concluded with foreign investors recording a substantial net buy of IDR 11.42 trillion. However, looking at the broader picture for the year 2026 so far, foreign investors have registered a total net sell, or outflow, amounting to IDR 37.61 trillion, indicating a more cautious stance over the longer term.
Providing a broader economic context, a presentation by the Financial System Stability Committee (KSSK) on May 7, 2026, highlighted the dynamic movements within the domestic capital market during the first quarter of 2026. This dynamism was attributed to increasing global uncertainty. Despite closing at 7,048.2 on March 31, 2026—a correction of 18.49 percent compared to the preceding quarter—the IHSG still demonstrated robust growth of 8.26 percent when measured against the same quarter of the previous year, underscoring its underlying resilience amidst fluctuating conditions.
