- Green cells indicate positive returns, red cells indicate negative returns. The darker the color, the stronger the move. Average and Median rows summarize each column across years.
What is Win %?
- Percentage of years when the period had a positive return. For example, 80% for January means January was positive in 80% of the years in the selected range.
