Jakarta Composite to 5,439.26: the BI-Rate hold case

The Jakarta Composite reaches 5,439.26 by November 18, 2026 in the base case, 5,863.78 in the bull case and 5,185.10 in the bear case, if Bank Indonesia repeats the 5.75% BI-Rate hold when the policy mix is set on the second day of the November 17-18, 2026 Board of Governors Meeting.

CNBC Indonesia, carried by jawawa, put the Wednesday, October 28, 2026 close at 5,282.31, up 16.18 points, or 0.31%, and GuruFocus lists the same completed-session print. The base case is the October 23 close of 5,439.26, a 156.95-point gap above that spot, while a completed close under the October 19 print of 4,996.61 ends the view. November 1 brings the reserve-requirement step, and the October 27 auction awarded 7.54% on the long bond.

How the October 28 close was fixed

The Jakarta Composite spot is the last completed cash session, Wednesday, October 28, 2026, at 5,282.31, carried as a press print and a data-vendor print because the Indonesia Stock Exchange daily-statistics page on idx.co.id returned HTTP 403 and the exchange's three-decimal sheet is absent. CNBC Indonesia via jawawa reported the Jakarta Composite Index (JCI), the IHSG on the Indonesia Stock Exchange (IDX), up 16.18 points, or 0.31%, from an open at 5,249.07. GuruFocus lists 5,282.31 for October 28, 2026 and 5,266.13 for October 27, 2026, so the 16.18-point rise is the gap between those two completed closes. An October 29 GuruFocus row at 5,142.82 and a stats-block last value of 5,147.14 were still an open session when read, and both stay outside the targets. A Yahoo Finance previous close of 5,266.13 matches October 27 and is used only as that prior session.

Where the completed closes sit around the spot

Every target in the base case is a completed close on the GuruFocus table, and every gap is subtraction from 5,282.31. The base case, 5,439.26, is the October 23, 2026 close and sits 156.95 points above the spot. The bull case, 5,863.78, is the October 15 close, the last print before the break to 5,185.10 on October 16, which is the bear case and 97.21 points under the spot. The invalidation line, 4,996.61, is the October 19 close, 285.70 points under the spot. GuruFocus states that 5,282.31 stood 18.8% under a long-term average of 6,503.90, inside a range of 223.25 to a record high of 9,134.7. The October 28 year-over-year column reads -34.73%, while a separate stats field shows 8,166.22 one year earlier and a change of -36.97%, and the level set keeps those two fields side by side.

Sources: GuruFocus Jakarta Composite table, October 15, 2026 through October 28, 2026, with the October 29 row left out. October 23 uses the October 22 close of 5,387.90, and October 15 uses the October 14 close of 5,943.02. A negative gap means the close sat under 5,282.31.

ANTARA matched the 16.18-point rise to 5,282.31, with healthcare up 1.72%, infrastructure down 2.44%, and breadth of 281 shares up, 429 down and 253 unchanged. Session value was Rp15.87 trillion in that wrap and Rp14.48 trillion at CNBC, so turnover stays out of the level set.

"Asian markets were mostly higher, following Wall Street’s gains overnight amid renewed optimism about artificial intelligence (AI). The rally came after Anthropic (Claude AI) was reported to be planning an IPO in mid-November 2026."

— Maximilianus Nico Demus, associate director of research and investment, Pilarmas Investindo Sekuritas (ANTARA via jawawa, October 28, 2026)

That listing remark is a company event, and the index horizon remains November 18, 2026. The same wrap put the 10-year market yield at 7.66% on October 28, separate from the 7.54% auction award.

Why a repeated BI-Rate hold maps to 5,439.26

The 156.95-point gap up to the October 23 close is the repair if Bank Indonesia (BI) repeats the BI-Rate hold. Release No. 28/233/DKom, at 5:00 p.m. on October 21, 2026 and signed by executive director Ramdan Denny Prakoso, held the BI-Rate at 5.75% and the Lending Facility at 6.50% while raising the Deposit Facility to 5.00%. The English Board of Governors Meeting schedule lists November 17-18, 2026 in Jakarta and says the policy mix is set on the second day, so the horizon is November 18, 2026, matching the October 21 publication of the October 20-21 decision. The same October 21 release cuts conventional reserves from 9% to 8%, and sharia reserves from 7.5% to 6.5%, on November 1. The December 1 cuts, including conventional reserves to 7%, sit after the horizon and get no weight.

September CPI was 3.28% year on year inside a 2.5±1% target, the rupiah was Rp17,985 per US dollar on October 20, down 0.61%, and reserves were USD146.3 billion. Portfolio inflows were USD0.66 billion as of October 19, with equity outflows still running, and the 7.54% awarded yield is the bear path towards 5,185.10. Compare the KOSPI base-rate case, the BIST 100 policy path, the TAIEX discount-rate hold and the Swiss Market Index hold case on the market-news desk.

"Since yesterday and today, we have started buying shares that we consider attractive. We will continue as long as prices are attractive and prospects are good."

What the level map leaves out

A print at 5,439.26 only retraces the late-October air pocket, while the long-term average of 6,503.90 and the record high of 9,134.7 remain far above the base. CNBC and ANTARA disagree on turnover, at Rp14.48 trillion and Rp15.87 trillion, so that figure stays out. The December 1 reserve step falls after November 18.

"Danantara’s presence is therefore better viewed as an additional catalyst, not a guarantee that share prices will continue to rise."

— Hendra Wardhana, market analyst, employing firm unnamed in the Liputan6 report (Liputan6 via jawawa, October 24, 2026)

What would end the Jakarta Composite base case

The base case to 5,439.26 by November 18, 2026 breaks if any one of these four observable signals prints.

• A completed close below 4,996.61, the October 19, 2026 GuruFocus print, would break the late-October swing before the meeting.
• A BI-Rate above 5.75% from the November 17-18, 2026 meeting would remove the hold in release No. 28/233/DKom.
• An auction award above 7.54% on the roughly 10-year line before November 18, the CNBC figure from October 27, would extend the yield pressure.
• A completed close above 5,863.78, the October 15 bull case, would mean 5,439.26 has stopped being the operative base.

What to watch before the decision day

Before November 18, 2026, watch the November 1 reserve cut, any new roughly 10-year auction yield, and the second-day BI-Rate. The map is 5,373.09 above the spot, 5,439.26 as the base, 5,185.10 as the bear case and 4,996.61 as the end of the view. December 15-16, 2026 stays outside the horizon.

TL;DR

The Jakarta Composite base case is 5,439.26 by November 18, 2026, the second day of the meeting listed as November 17-18, 2026. The spot is the October 28 close of 5,282.31, after the exchange statistics page returned HTTP 403. The bull case is the October 15 close of 5,863.78 and the bear case is the October 16 close of 5,185.10. GuruFocus states that the October 28 print stood 18.8% under the long-term average of 6,503.90. A completed close below 4,996.61 ends the base case, as does a BI-Rate set above 5.75%.

FAQ

What close does the Jakarta Composite base case use?

The base case uses the Wednesday, October 28, 2026 close of 5,282.31. CNBC Indonesia, carried by jawawa, reported a rise of 16.18 points, or 0.31%, from an open at 5,249.07. GuruFocus lists the same figure for October 28 and 5,266.13 for October 27, which matches the Yahoo Finance previous close and is used only as that prior session. The Indonesia Stock Exchange daily-statistics page returned HTTP 403, so the spot is a press print and a data-vendor print of the completed session.

Why is the horizon November 18, 2026?

Bank Indonesia's English calendar lists November as Tuesday-Wednesday, November 17-18, 2026, in Jakarta. The page says the monthly meeting runs over two days and that the policy mix is determined on the second day. Release No. 28/233/DKom, holding the BI-Rate at 5.75%, is timed 5:00 p.m. on October 21, 2026, the second day of the October 20-21 meeting. The index horizon follows that rule, so the decision day in the base case is November 18, 2026.

Where do 5,439.26, 5,863.78 and 5,185.10 come from?

Each figure is a completed close on the GuruFocus table. The base, 5,439.26, is the October 23, 2026 close, 156.95 points above the October 28 close of 5,282.31. The bull case, 5,863.78, is the October 15 close, the last print before the break to 5,185.10 on October 16, and that October 16 close is the bear case, 97.21 points under the spot. The invalidation line, 4,996.61, is the October 19 close. The long-term average of 6,503.90 stays context rather than a target.

What would show the BI-Rate hold case had failed?

A completed close below 4,996.61, the October 19, 2026 GuruFocus close, breaks the swing the base case treats as the floor. A BI-Rate above 5.75% from the November 17-18 meeting removes the hold in release No. 28/233/DKom. An auction before November 18 that awards above 7.54% on the roughly 10-year line, the CNBC figure from October 27, extends the yield pressure in the bear case. A completed close above 5,863.78 means the bull level has already printed and the base has been passed.
