How to Use Weekday Patterns

The Weekday Patterns tool shows historical return patterns by day of the week for any ticker. Select a ticker, then explore the data using the controls in the side panel.

• Summary / Detail: Summary shows average returns per weekday. Detail breaks down every individual occurrence.
• Return Mode: Switch between close-to-close and open-to-close returns to see how each day performs during different parts of the session.
• VIX Regime: Filter by VIX level to see how weekday patterns change in different volatility environments.

Use this to identify which days of the week have historically been strongest or weakest for your ticker, and whether that pattern holds across different VIX regimes.
