Indonesia's benchmark IDX Composite fell 1.93% at Monday's close, touching a six-month low as losses in Infrastructure, Financials and Agriculture dragged the market lower. Market breadth favored decliners by a wide margin, while a handful of small-cap names posted double-digit gains and losses. Oil and Brent futures rallied and the rupiah weakened against major currencies.

Key Points

  • IDX Composite fell 1.93% to a six-month low, with Infrastructure, Financials and Agriculture leading losses.
  • Market breadth was negative: 593 decliners, 166 advancers, and 103 unchanged.
  • Notable individual moves included large percentage gains for RO C K, TRIN and INTD, and sharp declines for POLA, NZIA and ALKA; oil futures rose while gold futures fell; the rupiah weakened versus the U.S. dollar and Australian dollar.

Indonesia's stock market closed lower on Monday, with the IDX Composite Index sliding 1.93% to register a new six-month low. The decline was led by sector-level losses in Infrastructure, Financials and Agriculture, which together pushed the market down over the session.

Market breadth on the Jakarta Stock Exchange skewed heavily negative: 593 stocks fell versus 166 that advanced, while 103 issues finished unchanged.

Among individual names, the session's strongest performers were Rockfields Property Indonesia Pt (JK:ROCK), which jumped 24.78% or 560.00 points to finish at 2,820.00; Perintis Triniti Properti PT (JK:TRIN), up 24.39% or 150.00 points to close at 765.00; and Inter-Delta Tbk (JK:INTD), which rose 23.81% or 50.00 points to end the day at 260.00.

Conversely, some stocks posted steep declines. Pool Advista Finance Tbk PT (JK:POLA) tumbled 14.94% or 13.00 points to trade at 74.00 at the close; Nusantara Almazia (JK:NZIA) fell 14.73% or 33.00 points to finish at 191.00; and Alakasa Industrindo Tbk (JK:ALKA) dropped 14.68% or 160.00 points to 930.00 in late trade.

Commodity markets showed notable moves during the session. Crude oil for May delivery advanced 2.04% or 1.98 to $98.82 a barrel. Brent oil for May delivery climbed 2.77% or 2.86 to $106.00 a barrel. By contrast, the April Gold Futures contract retreated 1.28% or 64.66 to trade at $4,997.04 a troy ounce.

Currency markets were also active. The Indonesian rupiah weakened against the U.S. dollar, with USD/IDR up 0.58% to 16,985.00. The Australian dollar likewise strengthened versus the rupiah, as AUD/IDR rose 0.83% to 11,918.49. The US Dollar Index Futures was down 0.07% at 100.04.


Separately, an investment product promotion included with market commentary highlighted model performance figures for AI-driven portfolios, noting year-to-date outperformance metrics and specific strategy returns. The promotional material cited that two out of three global portfolios were beating their benchmark indexes year to date, with 88% of portfolios in positive territory and a flagship Tech Titans strategy reportedly doubling the S&P 500 within 18 months, naming past winners. Readers should treat that content as separate from the market close data above.

Risks

  • Weakness concentrated across Infrastructure, Financials and Agriculture - these sector declines can amplify broader market downside.
  • Volatility in commodities and exchange rates - rising crude and Brent alongside a weaker rupiah may add uncertainty for importers and FX-sensitive companies.
  • Market breadth imbalance - the wide gap between falling and advancing stocks suggests elevated downside pressure that could persist in the short term.
