Flooring Guide by Cinvex – , JAKARTA — The Bisnis-27 Index concluded Monday’s early-week trading session on May 25, 2026, firmly in the green zone.

(BBRI), and PT Astra International Tbk. (ASII) were instrumental in propelling the index’s upward trajectory.

Throughout the trading day, the index demonstrated volatility, fluctuating between an intraday low of 437.06 and reaching a high of 449.22.
In terms of market liquidity, the total transaction value for stocks comprising the Bisnis-27 Index reached an impressive IDR 8.02 trillion. This substantial figure was underpinned by a trading volume of approximately 7.63 billion shares, with a total transaction frequency recorded at 481.6 thousand times, indicating active investor participation.
A closer look at the index’s constituents revealed a mixed but predominantly positive performance. A total of 14 constituent stocks advanced, while 12 ended the day in negative territory. The remaining single constituent stock exhibited relative stagnation, holding its ground amidst the market’s movements.
The primary drivers behind the index’s rise included significant gains from several key players. PT Indofood CBP Sukses Makmur Tbk. (ICBP) saw its shares climb 4.03% to IDR 7,100, while PT Bank Rakyat Indonesia (Persero) Tbk. (BBRI) recorded a 3.93% increase, closing at IDR 3,170. Further contributing to the rally was PT Astra International Tbk. (ASII), which strengthened by 3.70% to IDR 5,600.
Following closely, PT Bank Central Asia Tbk. (BBCA) posted a gain of 3.39% to reach IDR 6,100, and PT Perusahaan Gas Negara (Persero) Tbk. (PGAS) rose 3.02% to IDR 1,875. These leading stocks collectively played a crucial role in enhancing overall investor confidence and the index’s performance.
Conversely, several constituent stocks experienced declines, exerting downward pressure on the index. PT Sumber Alfaria Trijaya Tbk. (AMRT) saw a notable drop of 9.12% to IDR 1,295, followed by PT Bumi Resources Tbk. (BUMI), which fell 7.57% to IDR 171. PT Darma Henwa Tbk. (DEWA) also weakened significantly, declining 7.41% to IDR 350.
Further contributing to the downside, PT Triputra Agro Persada Tbk. (TAPG) decreased by 5.86% to IDR 1,525, and PT Medco Energi Internasional Tbk. (MEDC) saw its shares weaken by 5.22% to IDR 1,270. These weaker performances somewhat tempered the broader market’s gains.
The research team at Phintraco Sekuritas attributed the positive market sentiment to indications of progress in peace efforts aimed at resolving the Middle East conflict. This development led to a correction in oil prices, following reports of ongoing negotiations between the US and Iran potentially ending the war, which in turn alleviated concerns regarding US inflation.
On May 23, President Trump had stated that an agreement was being drafted to reopen the Strait of Hormuz. However, Iranian news agencies promptly denied this claim, with Iranian state media reporting that dozens of vessels had already transited the strategic waterway under Iranian supervision. The ongoing developments surrounding a potential US-Iran agreement and its implications for global oil prices are expected to continue shaping global market dynamics.
Domestically, market participants are keenly awaiting the MSCI rebalancing slated for the end of this month, which occurs amidst a truncated trading week. Furthermore, investors are anticipated to maintain a cautious stance due to the prevailing uncertainty surrounding the implementation of various new government policies, adding a layer of prudence to investment decisions.
