●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, −8.7% over these six months
The closing price of each day, from 0.10 on 2026-05-11 to 0.09 on 2026-11-05. 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.

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.
Insiders' buying price vs the latest close
Insiders paid 0.0929 HKD a share on average (1 purchase line, 1 buyer, 2026-09-07 – 2026-09-07). The close on 2026-11-05 was 1.2% above that price.
