Insiders Split: CEOs Sell, Chairs Buy

The most recent insider filings show a sharp divide between executives cashing out and board chairs stepping in with fresh capital.

The largest C-suite disposal came from ROBOTIS Co., where CEO Kim Byeong Soo filed the sale of 366,525 shares worth $75 million on 8 September. The trade represented roughly 0.2% of the company. No prior buying pattern was on record for the name, making the size of the exit notable.

A contrasting signal emerged from Turkish industrial firm Burçelik Vana Sanayi ve Ticaret. Chairman Umit Gumus filed a purchase of 1.07 million shares worth $12.9 million, filed on 8 September. At almost the same moment, asset manager Bulls Portföy Yönetimi sold a near-identical block of 1.07 million shares for $13.6 million. The chairman buying into an institutional exit is a rare show of conviction at the board level.

Hong Kong-listed 1888 Kingboard Laminates Holdings saw coordinated buying. Parent company Kingboard Holdings and Executive Chairman Cheung Kwok Wa both filed purchases on 8 September, together spending just over $7 million. Insider clusters of this type, with the parent company and a named executive moving together, tend to carry more weight than a single filing.

In Indonesia, two insiders at PT Bukalapak.com filed purchases totalling $10.2 million on 8 September. Major shareholder PT Kreatif Media Karya and board commissioner Adi Wardhana Sariaatmadja both bought in size, adding to positions at the e-commerce group.
