Shows historical monthly return patterns for each ticker.
The Graph chart shows the typical return per month; the Detail heatmap shows a year-by-month grid.
Toggle Median vs Average to switch the aggregate statistic each month uses.
Median: the middle month’s return — robust to outlier years like 2008 or 2020.
Average: the arithmetic mean — includes extreme years in full, so a single crash year can pull a month into the red.
