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
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 2014-05-06 to 2026-10-09 (3,015 trading days), $1 invested
overnight-only would now be worth $6.96;
$1 invested intraday-only would be worth $0.53.
CNPF'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.
