Jakarta — Indonesia’s renewable energy stocks closed the week with mixed results, marked by heavy volatility in Arkora Hydro (ARKO) and sharp swings in Barito Renewables (BREN) and Kencana Energi Lestari (KEEN).
Arkora Hydro (ARKO) was one of the most volatile counters. After starting the week at IDR 1,835, the stock slumped to IDR 1,510 on Wednesday, only to rebound briefly on Thursday before settling at IDR 1,525 on Friday. ARKO ended the week down 17 per cent, with total trading volume above 14.5 million shares.
Barito Renewables Energy (BREN) also saw wide fluctuations. The stock opened Monday at IDR 8,925, dropped midweek to IDR 8,800, and staged a strong recovery to IDR 9,025 by Friday. Despite the turbulence, BREN closed 1.1 per cent higher week-on-week, with more than 186 million shares traded and a transaction value exceeding IDR 1.6 trillion.
Kencana Energi Lestari (KEEN) enjoyed an early rally, peaking at IDR 1,050 on Wednesday. However, gains were short-lived as selling pressure dragged it down to IDR 980 by Friday, leaving it 19.5 per cent higher than Monday’s open of IDR 820 but below its weekly high. Trading volumes were robust, exceeding 108 million shares.
Pertamina Geothermal Energy (PGEO) experienced a rollercoaster week. After climbing to IDR 1,410 on Tuesday, the stock fell sharply midweek before closing at IDR 1,345 on Friday, just 0.4 per cent higher than Monday’s open of IDR 1,340. PGEO remained one of the most liquid counters, with 308 million shares traded across the week.
Other movers included Hero Global Investment (HGII), which reached intraday highs of IDR 162 on Tuesday but ended the week flat at IDR 148. Maharaksa Biru Energi (OASA) slipped marginally from IDR 240 to IDR 228, despite heavy daily volumes surpassing 500 million shares across the week. Semacom Integrated (SEMA) traded quietly but edged up slightly to IDR 101. Meanwhile, Terregra Asia Energy (TGRA) remained unchanged at IDR 27 with no recorded trades.
Market watchers noted that the week reflected investor caution amid global market uncertainty, with substantial liquidity in BREN and PGEO offset by volatility in ARKO and KEEN. They expect sentiment in the renewable sector to remain mixed in the near term, with selective buying focused on large-cap stocks. (nsh)
