## Cara halaman ini dibuat

Sumber: keterbukaan informasi dan laporan kepemilikan IDX, daftar pemegang saham dan laporan komposisi bulanan emiten, serta harga penutupan IDX. Setiap baris tertaut ke dokumen sumbernya.

Angka kepemilikan dibaca otomatis dari PDF. Laporan yang ekstraksinya masih diproses atau tingkat keyakinannya di bawah 70% tidak ditampilkan sebagai fakta.

Tidak ada di halaman ini: Running Trades, aliran dana broker, kedalaman orderbook, dan harga intraday. Semua itu tersedia di terminal setelah masuk.

Data riset, bukan saran investasi.
