๐ Seasonality โ 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.
From 2016-01-04 to 2026-10-09 (2,700 trading days), $1 invested
overnight-only would now be worth $0.31;
$1 invested intraday-only would be worth $5.03.
ILMN'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 โ
it ignores transaction costs and slippage.
