Risks

  • Sector-specific declines in Insurance, Sports and Basic Metals may continue to exert downward pressure on the index - these sectors were the session's primary negative contributors.
  • Volatility in commodity markets - June gold and oil contracts moved higher during the session - introduces uncertainty for energy and commodity-linked companies.
  • Currency fluctuations, exemplified by USD/TRY rising and EUR/TRY falling, add exchange-rate-driven uncertainty for exporters and importers.
