Tap an item for what it means.

●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.

▮Purple band: several insiders bought within 15 days

The band marks the stretch with the most different buyers: at most 15 days long and at least two people. Here it is 28 Apr – 4 May, with 2 insiders. Only the strongest stretch is marked. Several people deciding the same thing is harder to explain by one person's private reasons, but insiders often buy together just after a closed period ends, so compare it with the grey weekly bars.

Blue line: this share's price, −51.6% over these six months

The closing price of each day, from 7,010.00 on 2026-04-21 to 3,390.00 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 −51.6%, the typical one −31.9%, 19.8 points behind. It is not an index and not a comparison within one industry.

Shares of the reported value of insider transactions in the 180-day window. 2 line(s) are left out: the same person sold and bought the same number of shares on one day, which is a holding being moved, not a trade. 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.
