While the 20-week, 40-week, and 18-month cycles all remain in decline, a choppy counter-trend Santa Claus rally of uncertain
magnitude is expected into year-end early-January 2026 (see 'Schematic Structure of Hurst's Nominal 40-Day Cycle' below).
Next 80-day, 40-week, and 18-month troughs are currently projected to around January 25 (Mon), 2026.

each instrument are indicated in the stacked, color-coded boxes at the bottom right of the charts.]
