Risks

  • Elevated implied volatility as indicated by the CAC 40 VIX at a 52-week high, which may signal greater near-term price swings affecting equities and options traders.
  • Large downward moves in energy futures, with July crude and Brent both falling more than 5%, posing risks to energy and materials-related sectors.
  • Concentrated declines among specific large-cap names such as Capgemini and Ubisoft, which could weigh on the technology and consumer services segments.
