●A purchase: the bigger the dot, the more was bought
Each dot is one insider's purchases on one day. The dot's area follows the amount: the largest purchase here gets the largest dot. Hold the pointer over a dot to see the date and the amount.
×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, −52.3% over these six months
The closing price of each day, from 79,800.00 on 2026-04-21 to 38,100.00 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 −52.3%, the typical one −31.9%, 20.4 points behind. It is not an index and not a comparison within one industry.

Purchases against sales
Shares of the reported value of insider transactions in the 180-day window. Sales include disposals for tax, at option exercise or under a pre-set plan, which say little about an insider's view. The split describes what was disclosed; it is not a signal.
