Indonesia Bourse Flags 19 Stocks as Tightly Held

Indonesia’s stock exchange has named 19 listed companies with unusually concentrated share ownership. CNBC Indonesia reports the list is based on ownership data as of 1 October 2026, covering both physical and electronic shares.

What the bourse found

The companies come from a broad mix of sectors. They include palm oil and mining names Sawit Sumbermas Sarana, Golden Eagle Energy, Cita Mineral Investindo and J Resources Asia Pasifik; lenders Bank Maspion Indonesia, Bank Mayapada Internasional and Bank Mestika Dharma; tower operators Tower Bersama Infrastructure, Bali Towerindo Sentra and Dayamitra Telekomunikasi; property firms Citra Putra Realty, Indonesian Paradise Property and Duta Pertiwi; healthcare company Sarana Meditama Metropolitan; shipping firm Sillo Maritime Perdana; and consumer/food names Akasha Wira International, Diamond Food Indonesia, Enseval Putera Megatrading and Temas.

The exchange also removed two companies from the list: Panca Anugrah Wisesa and MD Entertainment.

What the regulator says

The Financial Services Authority (OJK) says being on the list is not a violation and will not trigger sanctions by itself. But OJK capital market chief Hasan Fawzi says concentrated-ownership stocks are more vulnerable to coordinated trading and price manipulation. Actively traded names on the list will face further examination.

The takeaway: this is a watchlist, not a penalty list. For traders in Southeast Asia, it is a useful screen for names where a small group of shareholders controls most of the stock.
