IHSG Plunges to New Low
Leading into the long holiday weekend, the Jakarta Composite Index (IHSG) closed with a sharp decline on Wednesday, May 13, 2026, signaling investor apprehension.
The IHSG plummeted by 135 points, marking a 1.98% drop to reach 6,723. This significant fall pushed the index to its lowest level in over a year, raising concerns across the market.
The primary pressure on the index stemmed from a substantial sell-off in large-capitalization (big-cap) stocks, following their removal from the prestigious MSCI Global Standard Indexes. This delisting triggered widespread investor reactions.
Among the stocks exerting the most downward pressure on the IHSG were prominent names such as TPIA, DSSA, AMMN, BREN, CUAN, and AMRT.
Furthermore, corrections were also observed in other significant big-cap stocks, including MORA, MLPT, and AALI, broadening the market’s downturn.

Basic Materials and Infrastructure Sectors Under Pressure
On a sectoral level, the most significant pressure was felt by the basic materials sector, which plunged by over 4.43%. Concurrently, the infrastructure sector also experienced a notable decline of 2.72%.
Several other key sectors, including energy, primary consumer goods, technology, non-primary consumer goods, and finance, also closed in the red, indicating a broad-based market correction.
Despite the overall downward pressure on the IHSG, the transportation sector managed to record a significant gain of 4.89%. Additionally, the industrial sector also showed resilience, climbing by 1.26%.
MSCI Sentiment Dominates Market Concerns
This latest weakening of the IHSG vividly underscores the considerable impact that changes in the MSCI index can have on domestic stock market movements.
The exclusion of several stocks from the MSCI index directly triggered an investor sell-off, intensifying pressure on big-cap stocks listed on the Indonesia Stock Exchange.
Foreign investors recorded a significant net sell across the Indonesian market, totaling IDR 1.53 trillion on Wednesday, May 13. The stocks experiencing the highest net sell by foreign investors included:
- PT Bank Rakyat Indonesia Tbk (BBRI): IDR 273.55 billion
- PT Bank Mandiri Tbk (BMRI): IDR 139.76 billion
- PT Amman Mineral Internasional Tbk (AMMN): IDR 134.73 billion
- PT Bank Central Asia Tbk (BBCA): IDR 91.76 billion
- PT Bumi Resources Tbk (BUMI): IDR 85.88 billion

Leading up to this holiday, the Jakarta Composite Index (IHSG) experienced a significant decline, falling 1.98% to 6,723 on May 13, 2026.
