Risks

  • Currency fluctuations, such as the noted decline in EUR/USD and movements in EUR/GBP, may affect export-sensitive companies and cross-border earnings for Belgian firms.
  • Narrow market breadth indicated by roughly equal numbers of advancers and decliners suggests limited directional conviction among investors during the session.
