Turkey’s equity benchmark ended the trading day lower on Friday, with the BIST 100 slipping 0.23% to close at a new one-month low. Weakness in the Technology, Sports and Information Technology sectors contributed to the decline.

The session mixed a few large individual stock moves with a generally softer market tone, as sector-level losses in Technology, Sports and Information Technology weighed on the headline index.

Risks

  • Market breadth was weak with more decliners than advancers, increasing downside risk for sentiment-sensitive sectors such as Technology and Information Technology.
  • Significant single-stock volatility - including large declines in some names - could amplify volatility in related sectors, notably Sports (sport-related equities) and Materials (for mining/metal firms).
  • Movements in commodities and currency pairs (gold, oil, USD/TRY, EUR/TRY) could add uncertainty for exporters, importers and firms with FX-sensitive balance sheets.
