Market Measures - March 5, 2021 - The Propensity of Streaks
tastytrade looks at what happens after streaks of up or down days.
Over the last 30 years, you could expect a streak of at least three 1% days to the same direction to happen less than 1% of the time, half being up-day streaks and half being down-day streaks.
The day after the end of a large down streak usually results in an above-average up day (+2.3%), whereas the day after the end of a large up streak results in a completely average down day.
