Istanbul Stocks Slip as Metals and Machinery Drag BIST 100 Lower

Turkey's benchmark BIST 100 closed lower on Thursday, retreating 0.36% as losses in the Sports, Basic Metals and Metal Products & Machinery sectors weighed on the market. Decliners outnumbered advancers by a wide margin, though several small- and mid-cap names posted double-digit percentage gains. Commodities and FX markets showed modest moves, with oil prices rising and the US Dollar index advancing.

Key Points

  • BIST 100 closed down 0.36% as Sports, Basic Metals and Metal Products & Machinery sectors underperformed.
  • Advancers were outnumbered by decliners, with 349 falling versus 248 rising; 21 stocks finished unchanged.
  • Commodities and FX saw modest upward moves: oil prices rose, gold ticked higher, USD/TRY increased and US Dollar Index Futures gained.

Turkey's equity market finished the trading day in negative territory on Thursday, with the BIST 100 index down 0.36% at the close in Istanbul. Pressure came from a handful of sectors led by Sports, Basic Metals and Metal Products & Machinery, which collectively contributed to the downward momentum.

Market breadth was tilted toward selling: 349 stocks fell while 248 rose, and 21 shares finished unchanged. That skew reflects the concentrated nature of the session, where a small group of names posted outsized gains while a larger number of issues retreated.

  • Efor Yatırım Sanayi ve Ticaret A.Ş. (EFOR) climbed 9.96%—an increase of 0.67 points—ending the day at 7.40.
  • Kontrolmatik Teknoloji Enerji ve Mu (KONTR) advanced 9.95% or 1.08 points to close at 11.93.
  • Ral Yatirim Holding AS (RALYH) gained 9.92%, a jump of 28.00 points, to finish at 310.25. The move pushed RALYH to an all-time high at the close.

Largest decliners

  • Dap Gayrimenkul Gelistirme AS (DAPGM) slipped 4.89% or 0.55 points, closing at 10.70.
  • MLP Saglik Hizmetleri AS (MPARK) fell 3.69%—a 17.50-point drop—to end at 456.50.
  • Tofas Turk Otomobil Fabrikasi AS (TOASO) declined 3.60% or 10.75 points to close at 288.25.

Commodities traded with notable moves: Gold futures for June delivery rose 0.05%—up 2.56—to $4,826.16 a troy ounce. Crude oil for May delivery increased 2.60% or $2.37 to $93.66 a barrel, while the June Brent contract moved up 3.59% or $3.41 to $98.34 a barrel.

Foreign-exchange and dollar benchmarks showed modest strength. USD/TRY was higher by 0.06% at 44.76, while EUR/TRY was unchanged at 52.83. The US Dollar Index Futures ticked up 0.19% to 98.04.

The trading session illustrated a market where a small number of stocks outperformed sharply, but broader sector pressure - particularly in Metals and Machinery-related areas - pushed the headline index into negative territory by the close.


Note: market moves and individual stock performances referenced above reflect closing prices and percentage changes reported at the Istanbul close on Thursday.

Risks

  • Market breadth risk - a larger number of decliners (349) versus advancers (248) suggests downside pressure across multiple sectors, notably Basic Metals and Metal Products & Machinery.
  • Commodity-price volatility - rising crude benchmarks could affect energy-linked sectors and broader market sentiment.
  • Currency sensitivity - movements in USD/TRY and EUR/TRY and a firmer US Dollar Index Futures may increase FX-linked earnings volatility for exporters and importers.
