Jakarta Composite Opens at 5,397, Extends Thursday's 1.12% Rebound

Indonesia's benchmark index, the Jakarta Composite (IHSG), opened 0.18% higher at 5,397.34 on Friday morning, October 23, 2026, up 9.43 points from the previous close. The move extends a sharp rebound from Thursday, when the index reversed out of negative territory and finished the day up 1.12%.

A Sharp Reversal From Deep in the Red

Thursday's session, October 22, 2026, ranked among the most volatile on the Indonesia Stock Exchange this week. The index opened at 5,247.98, at one point sliding as much as 2% in early trade. From there, it reversed course and climbed steadily through the day, eventually touching an intraday high of 5,422.59.

By the close, the index settled at 5,387.91, up 59.54 points or 1.12% from the prior session. The gap between the day's low and high topped 174 points, a wide range for a single trading day on the IHSG.

Traders sometimes call this kind of pattern, a red open that flips to a green close, a one-day V-shaped recovery. It typically happens when early panic selling gives way to aggressive buying once prices are seen as oversold.

What Was Said to Drive the Mood

Investors were reportedly watching several factors during Thursday's session, including Bank Indonesia's policy decision and a statement from President Prabowo related to MSCI. MSCI is the index provider that many foreign fund managers use as a benchmark for allocating money to emerging markets, Indonesia included. Comments tied to MSCI tend to draw market attention because they can signal shifts in foreign fund flows into stocks listed on the exchange.

Friday morning's open was also shaped by a mix of domestic and global sentiment, including Japan's inflation data released ahead of the Asia trading session. Japan's inflation numbers matter to regional markets because they feed into expectations for the Bank of Japan's policy path, which in turn can sway capital flows and currencies across Asia, including the rupiah.

That blend of local and external drivers has kept the index's direction choppy from one day to the next, rather than settling into a clean trend.

Turnover Stayed Heavy

Activity on Thursday was substantial. Trading volume reached 331.29 million lots, with transaction value around Rp15.31 trillion, precisely Rp15,313.18 billion. One lot on the exchange equals 100 shares, so that volume reflects millions of individual trades across the session.

Heavy volume and value during a reversal from the day's low usually points to active buying from a broad range of participants, including institutions, stepping in while prices were temporarily discounted. The larger the transaction value during such a rebound, the stronger the signal that the move is backed by real buying interest rather than just short-term technical positioning.

LQ45 Rose by a Smaller Margin

The LQ45 index, which tracks 45 of the exchange's most liquid, large-cap stocks, also opened higher on Friday, up 0.56 points or 0.10% to 545.13. LQ45 is often used as a proxy for blue-chip stock performance on the exchange.

The fact that LQ45 rose by a smaller margin than the broader index on Friday's open suggests the morning's gains weren't driven entirely by large-cap names. There are signs that stocks outside the LQ45 basket, including second and third-tier names, also contributed to the index's advance.

What It Means for Investors

A few levels are worth tracking in the sessions ahead. The 5,247.98 mark is the low the index touched at Thursday's open, while 5,422.59 stands as this week's intraday high. A push back toward or past 5,422 could suggest the rebound still has room to run.

On the other hand, if the index fails to hold above the 5,387 to 5,397 range, renewed selling pressure similar to Thursday's early dip could resurface. The sharp reversal from a red open shows that intraday volatility remains elevated, meaning price swings within a single day could stay wider than usual.

Daily trading volume is also worth watching as a secondary gauge. A repeat of Thursday's roughly Rp15 trillion in turnover would point to strong market participation, whether the index moves up or down. Conversely, thinner volume on an up day could hint that the gain lacks solid buying support.

External sentiment, including Japan's inflation data and the Bank of Japan's policy direction, remains a factor worth monitoring since it could trigger volatility similar to what played out this week. On the domestic side, any follow-up on the MSCI-related statement is also worth watching, given its link to potential foreign fund flows into Indonesian equities.

What level did the index open at today?

Why did the index drop sharply before rebounding on Thursday?

The sources don't specify the exact trigger for the early dip. The index opened in the red at 5,247.98 and then reversed through the day, with traders said to be watching Bank Indonesia's decision and a statement related to MSCI.

What's the difference between LQ45 and the broader index?

The Jakarta Composite covers all stocks listed on the exchange, while LQ45 includes only 45 of the most liquid, large-cap names. The two can move by different margins depending on which stocks are most actively traded on a given day.
