Last 59 trading days. "Overnight" = today's Open vs the PRIOR day's Close
(the same move plotted as the pink dotted line on the chart) — each day's own Open→Close
move is not counted here. Overnight $/% is what you'd have earned holding only from close
to next open; Cum. Index is the running compounded value shown on the chart's pink line.

📅 Seasonality — Adjusted Close by Year
Each line is one calendar year's adjusted close price (split- and dividend-adjusted, so a stock split does not show as a
crash), or the % change from that year's first trading day in "% from Jan 1" mode, aligned by month/day so the same point in the calendar lines
up across years. Most recent year is drawn thicker. Click a year in the legend to hide/show it.
🌙 Overnight vs. Intraday Return
Not enough historical data yet for this ticker to compute an overnight/intraday split.
