  • Catalysts for market turbulence next year include midterm elections, a new Federal Reserve chair, Supreme Court rulings on tariffs, and potential government shutdowns.
  • Defensive sectors like health care, consumer staples, and utilities have historically performed well during midterm election years.
  • The market often sees a positive reversal and rally in the fourth quarter of a midterm election year.
  • Projections suggest the S&P 500 could finish 2026 between 8% and 12% higher, continuing a streak of positive years.
