JCI Remains Under Pressure, Session II Closes 0.43% Weaker at 6,121
The Indonesia Composite Index (JCI) moved fluctuated during trading on Tuesday, 29 September 2026. At the close of the second session today, the JCI fell by 26.16 points or 0.43% to the level of 6,121.70.
In terms of trading activity, transaction volume was recorded at 383 million lots with a transaction value reaching Rp13.24 trillion. A relatively wide daily movement range of approximately 137 points, from a low of 6,013 to a high of 6,150, reflects high volatility and a cautious stance among market participants.
Throughout today’s trading, the JCI’s decline was weighed down by 373 declining stocks, 118 unchanged stocks, and only 303 gaining stocks.
The non-primary consumer, property, and basic materials sectors experienced the deepest corrections today. Specifically, shares of GOTO, BBCA, and BREN were the primary drags on the JCI’s performance.
Pressure on the JCI coincided with the implementation of a new Indonesia Stock Exchange (IDX) policy, which reduced the minimum share price from Rp50 to Rp1 per share in the regular and cash markets starting Monday (28/09/2026).
This change is accompanied by adjustments to auto-rejection limits. For shares priced between Rp1 and Rp10, the Upper Auto Rejection (ARA) and Lower Auto Rejection (ARB) limits are set at Rp1, while the 15% asymmetric ARB remains applicable for shares priced above Rp10 until the end of 2026.
The IDX stated that the change in minimum price is intended to expand the trading range of stocks, improve the quality of price discovery, boost liquidity, and provide greater flexibility for investors in managing their portfolios.
Simultaneously, external pressures continue to shadow the domestic market. Tighter global monetary policies, the strengthening of the US dollar, rising energy prices, and high global interest rates still have the potential to drive volatility in emerging market financial markets, including Indonesia.
In the currency market, the rupiah weakened again against the US dollar during the start of the trading week.
