Risks

  • Uncertainty around the Federal Reserve interest rate decision, which could affect market direction and sector performance - impacts broad market and financial sectors.
  • Ongoing developments in the Iran war that may disrupt supply chains and inputs, as cited by Mizuho in its downgrade of CF Industries - impacts fertilizers and agricultural supply-related industries.
  • Analyst downgrades and guidance shortfalls can trigger stock-specific volatility, as seen with Duolingo's downgrade and Lululemon's below-estimate 2026 forecast - impacts retail, consumer discretionary and software sectors.
