🌙 Overnight PnL Breakdown

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 — Close Price by Year

Years back

Each line is one calendar year's close price (or % 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

Overnight (close→next open) Intraday (open→close)

From 2010-01-04 to 2026-09-28 (4,113 trading days), $1 invested overnight-only would now be worth $1,499.73; $1 invested intraday-only would be worth $0.00. 044380's historical return has leaned mostly on the overnight session. This reflects a statistical pattern in past prices, not a trading strategy or investment advice — it ignores transaction costs and slippage.
