The session closed with a clear split between individual winners and losers across sectors, and with commodity and currency markets registering material intraday shifts. Market participants will likely watch whether the breadth observed today broadens or narrows in subsequent sessions.

Risks

  • Broad selling pressure across multiple sectors could weigh further on index performance - impacts Banking, Telecoms and Sports names.
  • Volatility in commodities such as crude oil and gold may influence market sentiment and sector-level returns - impacts energy and materials-related firms.
  • Movements in USD/TRY and EUR/TRY exchange rates may affect exporters, importers and financial firms operating in lira-denominated markets - impacts financials and trade-exposed sectors.
