Bangchak Corporation Public Company LimitedNamed as a top pick in the refining group, supported by recovering Singapore refining margins (up $3.17 to -$1.44/bbl).
DBS Vickers Securities (Thailand) said in an analysis that it is maintaining its Neutral investment weighting on energy and petrochemical stocks, noting that the five business groups, namely upstream, refining, petrochemicals, power plants, and oil retail, each have different drivers. It highlighted eight top picks. The upstream group, which includes PTTEP and PTT, faces short-term pressure from lower oil prices, with Dubai crude falling 11.84 US dollars to 113.06 US dollars per barrel, though still well above the 2025 average of about 70 US dollars per barrel. The top pick in this group is PTTEP. The refining group, which includes BCP, IRPC, PTTGC, SPRC, and TOP, is supported by a recovery in Singapore refining margins of 3.17 US dollars to minus 1.44 US dollars per barrel. The top picks are BCP and SPRC. The petrochemical group, which includes IRPC, IVL, PTTGC, SCC, and TOP, benefits from a broad increase in price spreads after naphtha prices fell 33 US dollars per ton. The top picks are PTTGC and SCC. The power plant group, which includes BGRIM, GPSC, and GULF, has improved in the short term on weaker JKM gas prices, down 1.80 US dollars to about 26 US dollars per million British thermal units. The top picks are GULF and GPSC. The oil retail group, which includes OR and PTG, benefits from a 0.71 baht increase in diesel marketing margins to 2.00 baht per liter after pump retail prices were raised on September 24, 2026. The top pick is PTG.
