JCI Plunges 1.14% in Morning Session, Big Cap Shares Become a Burden

JAKARTA, KOMPAS.com - The Composite Stock Price Index (JCI) closed sharply down in the first trading session on Monday (11/5/2026). Selling pressure on large-cap stocks caused the index to correct significantly. Based on data from the Indonesia Stock Exchange (BEI), the JCI closed 1.14% weaker at 6,890.272 at the end of the morning session. The index correction was triggered by selling actions on several blue-chip stocks that have substantial weight in market movements. Shares of PT Bank Mandiri Tbk (BMRI) also fell 8%. Meanwhile, PT Barito Renewables Energy Tbk (BREN) weakened 5.1% and PT Chandra Asri Pacific Tbk (TPIA) corrected 5%. Pressure on blue-chip stocks caused the JCI movement to lag behind the majority of stock indices in the Asian region. By midday, most major Asian exchanges were indeed moving lower. However, the corrections were relatively more limited compared to the domestic stock market. The Shanghai exchange even managed to stay in positive territory with a gain approaching 1%. In terms of sectors, only two sectoral indices held in the green zone. The transportation and energy sectors were the two with the deepest declines and added pressure to the JCI throughout the morning session. The selling pressure then dragged the index to its lowest point in the 6,846.632 area before moving in the 6,880 to 6,890 range until the end of the first session. Trading activity was observed to be brisk. Transaction volume reached 24.178 billion shares with a transaction value of Rp 11.449 trillion. Trading frequency was recorded at 1.69 million transactions. Of all the stocks traded, 439 stocks were in the red zone. That number was far more than the 236 stocks that strengthened. Meanwhile, 138 other stocks moved stagnant.
