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.
