Aylin Güneş Note: The BIST 100’s sharp decline reflects heightened geopolitical risks and structural concerns over Turkey’s current account dynamics. The financial leasing sector’s steep drop underscores tightening credit conditions and rising rates. Investors should monitor the 14,000-point support level closely, favoring dividend-paying stocks and sectors with currency-hedged stability.
