- The IDX Composite closed at 5,344.41 on Friday, up 1.78 percent.
- All 11 domestic sectors advanced, led by technology, commodities and energy.
- New High Shareholding Concentration rules removed 383 stocks from the index calculation from November 13.
The IDX Composite ended Friday, November 13, at 5,344.41, gaining 1.78 percent in Jakarta. The advance came as all 11 domestic sectors strengthened, while Indonesia's revised rules for stocks with highly concentrated ownership took effect.
Katadata reported that technology stocks led the sector advance with a gain of 3.94 percent. Commodity and energy stocks followed with increases of 3.53 percent and 2.49 percent, respectively. Trading involved 30.35 billion shares across 1.51 million transactions, with total transaction value of about IDR 12.38 trillion.
Broad gains across domestic sectors
Market breadth was positive: 319 stocks closed higher, 72 were unchanged and 66 declined, according to the same Katadata account. ESIP was the strongest performer, rising 34.72 percent, while WMUU and ARKO gained 32.43 percent and 24.77 percent. MMIX was the weakest stock in the reported session, falling 6.85 percent.
The index advance took place despite mixed regional trading. Katadata cited declines in the Hang Seng, Shanghai Composite and Straits Times indexes, while the Nikkei 225 rose. The IDX Composite's move therefore came alongside a varied Asian market backdrop rather than a uniform regional advance.
Revised composition affects index calculation
Friday also marked the implementation of a change to the IDX's treatment of concentrated ownership. VOI reported that the exchange excluded 383 stocks from the Composite Stock Price Index calculation from November 13. Under the revised approach, stocks are classified as having High Shareholding Concentration when 10 shareholders or fewer control at least 92.5 percent of the company's shares.
The change does not delist the affected companies. They remain listed on the IDX but are excluded from the index calculation while they have HSC status. For investors tracking the IDX Composite, the adjustment changes the set of shares contributing to the benchmark and may affect how market breadth and performance are interpreted.
