Price vs insider buying

9688.HK · HKD

● Purchase　× Sale　◇ Public disclosure　▥ 15-day cluster ·

Circles and crosses mark trade dates; diamonds below the axis mark later public disclosures. The trade became public on its disclosure date. Prices are nearest-session closes, not insider execution prices. Marker sizes are not compared when values or currencies differ.

Insider timeline

One insider bought, once (1 Jul). The share closed at 14.99 that day and at 18.17 most recently (+21.2%).

●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, +20.1% over these six months

The closing price of each day, from 15.13 on 2026-05-11 to 18.17 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.

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

No purchase price could be compared with the share price (price or share count missing, another currency, or far from that day's close).
