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.

Blue line: this share's price, −26.2% over these six months

The closing price of each day, from 2,450.00 on 2026-04-21 to 1,809.00 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 −26.2%, the typical one −31.9%, 5.7 points ahead. It is not an index and not a comparison within one industry.
