JCI Jumps 1.21% Despite Rp630 Billion Foreign Outflow: 10 Stocks Still Bought

Indonesia's stock market extended its rebound on October 6, with the Jakarta Composite Index gaining 1.21% to 6,192.93.

All 11 IDX sector indices finished higher, while transport and logistics led the market with a 3.16% gain. Technology rose 3.09% and energy advanced 2.67%.

But the rally came with an unusual feature.

Foreign investors remained net sellers overall.

They recorded approximately Rp629.87 billion in net selling across all markets, even while selectively adding positions in several listed companies.

The Rally Was Broad

Market breadth was clearly positive.

A total of 489 stocks advanced, compared with 183 decliners and 120 unchanged shares.

Trading value reached around Rp12.35 trillion, with approximately 48.23 billion shares changing hands in 1.88 million transactions.

Every sector ended the session higher.

The breadth of the advance suggests that the JCI's gain was not simply the result of one or two heavyweight stocks.

Foreign Investors Still Sold More Than They Bought

The foreign-flow picture was very different.

All-market foreign net selling reached Rp629.87 billion.

In the regular market, net selling totaled approximately Rp597.49 billion, while the remaining outflow came from negotiated and cash-market transactions.

A negative net figure does not mean foreign investors stopped buying Indonesian equities.

It simply means their total sales exceeded total purchases.

That distinction becomes clear when looking at individual stocks.

TPIA Led Foreign Buying

Chandra Asri Pacific recorded the largest foreign net inflow, at approximately Rp58.91 billion.

Bank Rakyat Indonesia followed with Rp45.80 billion.

Timah attracted around Rp38.24 billion, while Aneka Tambang received Rp35.76 billion and Bukit Asam Rp26.91 billion.

These five stocks also appear as the leading foreign inflows in Indo Premier's October 6 market summary.

Ten Stocks in the Stockbit Ranking

The Stockbit ranking cited by the source article listed the following stocks:

The ranking reflects the Stockbit snapshot reported in the underlying CNBC Indonesia material.

Commodity-Linked Stocks Dominated the List

A notable share of the buying list is connected to commodities and energy.

TINS is exposed to tin, ANTM to nickel and gold, PTBA and BUMI to coal, AMMN to copper and gold, while ENRG and MEDC operate in the energy sector.

That concentration may suggest selective foreign interest in resource-related equities.

However, one trading session is not enough to establish a sustained sector rotation.

Evidence of a longer-term allocation shift would require repeated buying over several sessions.

BBRI Stood Out Among the Banks

BBRI was the second-largest foreign net-buy stock.

That does not mean foreign investors were uniformly buying Indonesian banks.

Institutional investors can increase exposure to one bank while reducing holdings in another.

Stock-level flows therefore provide more information than simply assuming all companies in the same sector are being treated alike.

Heavy Selling Elsewhere Kept Overall Flow Negative

At the same time, other large stocks faced substantial foreign selling.

GOTO recorded the largest foreign net outflow at approximately Rp255.8 billion.

Bank Mandiri followed with Rp127.2 billion, while Telkom Indonesia recorded about Rp73.1 billion in selling.

These large outflows help explain why aggregate foreign activity remained negative even though several individual stocks attracted significant buying.

Why Could the JCI Rise During Foreign Outflows?

The JCI is determined by the weighted price movements of its constituent stocks, not simply by foreign investor flows.

Domestic investors can absorb shares sold by overseas investors.

A broad increase across sectors can also support the benchmark even when international investors are reducing aggregate exposure.

That is exactly what the October 6 data illustrate.

A 1.21% index gain and Rp629.87 billion in foreign net selling can occur simultaneously because they measure different aspects of market activity.

Foreign Buying Did Not Necessarily Cause the Rally

It is tempting to say that the ten foreign-buying stocks “pushed the JCI higher.”

The available flow data alone do not establish that causal relationship.

A stock's impact on the JCI depends primarily on its price movement and index weight.

Foreign net buying simply indicates that foreign purchases exceeded foreign sales during the reporting period.

The more accurate conclusion is that these stocks attracted overseas buying while the broader market was rallying.

Why Do Rankings Differ Across Data Providers?

Foreign-flow lists may differ between trading platforms.

One October 6 market recap, for example, listed DSSA, MEDC, BRMS and MAPI among the lower positions of the largest foreign inflows, rather than BUMI and AMMN.

The CNBC Indonesia article citing Stockbit used the BUMI-AMMN-DSSA-MEDC sequence.

Differences can arise from market scope, transaction classifications, or the timing and methodology of each snapshot.

For that reason, rankings should always be interpreted with their data source attached.

Foreign Net Buying Is Not a Buy Signal

A stock attracting foreign funds during one session is not guaranteed to rise afterward.

Institutional investors trade for many reasons, including portfolio rebalancing, index changes, liquidity management and short-term risk adjustments.

Foreign-flow data become more useful when combined with company fundamentals, valuation, volume and multi-session trading patterns.

Bottom Line

Indonesia's JCI rose 1.21% to 6,192.93 on October 6, with all 11 sectors ending higher.

Foreign investors nevertheless recorded approximately Rp629.87 billion in all-market net selling, including Rp597.49 billion in the regular market.

Selective buying remained visible.

In the Stockbit ranking used by the source material, TPIA led foreign net purchases, followed by BBRI, TINS, ANTM, PTBA, ENRG, BUMI, AMMN, DSSA and MEDC.

The key point is that aggregate foreign selling does not mean foreign investors are abandoning every Indonesian stock.

They can reduce overall market exposure while continuing to build positions in selected companies.
