×A sale
A cross is one insider's sales on one day. People sell to pay tax, to cash in share awards or to hold less of one company, so a sale says less than a purchase does. When someone bought and sold on the same day, the cross sits beside the dot. The totals are under “Purchases against sales” below.
Blue line: this share's price, +0.7% over these six months
The closing price of each day, from 128,400.00 on 2026-04-21 to 129,300.00 on 2026-10-16. The line has no scale; read it for high and low: a dot on a low stretch was bought cheaply, a dot on a high stretch was not.
Dashed line: the typical stock on the same exchange, −31.9%
Taken from the 1525 other stocks on the same exchange that this site holds prices for. Each is measured from the first day of the window, and every day the middle one is drawn. It starts where the blue line starts, so the gap between the two is the difference: this share +0.7%, the typical one −31.9%, 32.6 points ahead. It is not an index and not a comparison within one industry.
