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.

🌙 Overnight vs. Intraday Return
Overnight (close→next open) Intraday (open→close)
From 1994-06-27 to 2026-09-04 (7,381 trading days), $1 invested
overnight-only would now be worth $0.42;
$1 invested intraday-only would be worth $8.51.
JGS's historical return has leaned mostly on the regular trading session (intraday).
This reflects a statistical pattern in past prices, not a trading strategy or investment advice —
it ignores transaction costs and slippage.
