Jakarta Stocks Climb as IDX Composite Advances 4.10% on Broad Sector Gains

Indonesia's benchmark IDX Composite rose 4.10% at Wednesday's close in Jakarta, with gains concentrated in the Infrastructure, Financials and Agriculture sectors. A handful of small- and mid-cap names delivered outsized moves to the upside, while select issues posted notable declines. Commodities saw sharp moves: WTI and Brent crude fell, and gold futures rose. FX shifts included a slight depreciation of the US dollar against the rupiah and an uptick in AUD/IDR.

Key Points

  • IDX Composite Index rose 4.10% at Wednesday's close in Jakarta, led by Infrastructure, Financials and Agriculture sectors.
  • Top gainers included Wijaya Cahaya Timber PT (FWCT), Ace Oldfields PT (KUAS) which hit a three-year high, and PT Royaltama Mulia Kontraktorindo Tbk (RMKO); several small- and mid-cap stocks posted large percentage moves.
  • Commodity and FX markets saw notable moves: WTI and Brent crude fell sharply while June gold futures rose; USD/IDR and AUD/IDR experienced modest shifts.

Shares on the Indonesia Stock Exchange ended higher Wednesday, powered by sector-wide advances in Infrastructure, Financials and Agriculture that pushed the IDX Composite Index to a 4.10% gain at the close in Jakarta.

The session featured several pronounced individual stock moves. Among the day's top performers was Wijaya Cahaya Timber PT (JK:FWCT), which climbed 34.18% - a rise of 27.00 points - to finish at 106.00. Ace Oldfields PT (JK:KUAS) added 26.36%, or 29.00 points, closing at 139.00, while PT Royaltama Mulia Kontraktorindo Tbk (JK:RMKO) rose 25.00%, or 107.00 points, to end the day at 535.00.

Not all components saw gains. Equity Development Investment (JK:GSMF) led decliners, sliding 14.58% or 21.00 points to 123.00 at the close. Sinergi Inti Plastindo (JK:ESIP) fell 10.38%, retreating 11.00 points to 95.00, and Lancartama Sejati Tbk (JK:TAMA) lost 9.03% or 13.00 points to finish at 131.00.

Market breadth favored advancers by a wide margin: 608 stocks rose, 139 fell and 111 shares closed unchanged on the Jakarta Stock Exchange.

Notably, Ace Oldfields PT (JK:KUAS) reached a three-year high in the session, gaining 26.36% to close at 139.00.

Commodities trading showed marked movement on the same day. Crude oil for May delivery dropped 14.61%, falling $16.50 to settle at $96.45 a barrel. Brent crude for June delivery declined 12.64%, down $13.81 to $95.46 a barrel. Precious metals moved in the opposite direction: the June Gold Futures contract rose 3.21%, an increase of $150.30, trading at $4,835.00 a troy ounce.

Foreign exchange rates recorded modest shifts. The USD/IDR exchange rate slipped 0.08% to 17,003.20, while AUD/IDR climbed 0.62% to 11,993.75. The US Dollar Index Futures decreased 1.07%, standing at 98.62 at the time referenced.


These developments reflect a session in which broad sector strength lifted the benchmark, even as commodity and currency markets displayed divergence that may influence sentiment in energy-sensitive and export-linked sectors.

Risks

  • Significant single-stock volatility was evident, with several names moving more than 25% in a session - a risk for investors in small- and mid-cap equities and sectors such as Timber and Contractors.
  • Sharp declines in crude oil prices could affect energy-sector valuations and companies exposed to oil-linked costs or revenues.
  • Currency fluctuations, indicated by moves in USD/IDR and AUD/IDR, may create uncertainty for exporters, importers and firms with foreign-currency exposures.
