JAKARTA — Jakarta Composite Index (JCI) plunged 5.91% over the past week (9–13/3). LQ45 Index, however, recorded an even steeper decline of 6.15%.

Data from the Indonesia Stock Exchange (IDX) show that LQ45 stocks were the main drag on the benchmark index this week.

Two companies from the Barito Group controlled by Prajogo Pangestu — PT Barito Renewables Energy Tbk (BREN) and PT Barito Pacific Tbk (BRPT) — for example, fell 18.45% and 11.9% respectively during the week, together pulling JCI down by around 63.35 points.

Meanwhile, weak performance from three state-owned companies — PT Bank Rakyat Indonesia Tbk (BBRI), PT Telkom Indonesia Tbk (TLKM), and PT Bank Mandiri (Persero) Tbk (BMRI) — also dragged JCI lower by 66.15 points.
