Seasonality in Markets
Historical patterns that repeat yearly
Markets exhibit seasonal tendencies based on capital flows, fiscal years, and behavioral patterns.
Forex seasonality: - USD: Typically strong in Q4 (year-end repatriation) - EUR: Often weak in summer (vacation, low volume) - JPY: Strengthens in March (Japanese fiscal year end) - AUD: Follows commodity cycles (China demand)
General patterns: - January effect: New year capital allocation - "Sell in May": Summer months historically weaker - September: Historically worst month for stocks - Q4 rally: Year-end window dressing - December: Thin liquidity = erratic moves
Use seasonality as confluence — not as a standalone trading system.
Pro tip: Check historical seasonal charts for the pair you're trading — they're surprisingly consistent over decades.
Common mistake: Blindly following seasonal patterns without technical confirmation. Better: Seasonality adds context but should always be combined with technical analysis.
Key takeaways
- USD strong in Q4, EUR weak in summer
