📅 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
Overnight (close→next open) Intraday (open→close)
From 2016-01-04 to 2026-10-23 (2,710 trading days), $1 invested
overnight-only would now be worth $2.05;
$1 invested intraday-only would be worth $0.87.
AKAM'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.
