Turkey's BIST 100 Index Ends 1.04% Lower on Sector Weakness

Turkey's benchmark BIST 100 index finished Tuesday's trading session in negative territory, closing down 1.04% amid sector-specific selling pressure, according to data from the Istanbul Stock Exchange.
Sector Performance and Market Breadth
The decline was primarily driven by weakness in several key industries. According to closing data, the Leasing & Factoring, Wood, Paper & Printing, and Chemical, Petroleum & Plastic sectors were among the most significant laggards, pulling the broader index lower.
Despite the headline index decline, market breadth was positive. Advancing stocks on the Istanbul Stock Exchange outnumbered decliners by a margin of 349 to 273, with 23 stocks ending the session unchanged. This suggests that the day's losses were concentrated in larger-cap companies with a heavier weighting in the BIST 100 index.
Notable Stock Movements
Several companies saw significant price swings during the session. The top performers on the BIST 100 included:
Ad- EIS Eczacibasi Ilac (ECILC): surged 9.93%
- Girisim Elektrik (GESAN): added 9.90%
- Enerya Enerji (ENERY): rose 6.50%
Conversely, the day's worst performers were led by Isiklar Enerji ve Yapi Holding AS (IEYHO), which fell 10.00%. Other notable decliners included Ral Yatirim Holding AS (RALYH), down 9.99%, and Pasifik Eurasia Lojistik (PASEU), which dropped 9.98% to a new 52-week low.
Currency and Commodity Markets
In the broader markets, the Turkish lira saw mixed movement. The USD/TRY pair edged up 0.06% to 48.82, while the EUR/TRY pair fell 0.17% to 55.88. The US Dollar Index Futures, which measures the greenback against a basket of currencies, rose 0.16%.
Commodity prices were generally lower. December Gold Futures traded down 0.31% to $4,370.25 per troy ounce. In energy markets, November contracts for both Crude and Brent oil also declined, falling 0.96% and 0.33% respectively.
