Insiders Buy the Dip From Seoul to Boston

The most striking open-market purchase in recent filings came from Servyou Software Group CEO Zhang Zhen Chao, who filed a $108m buy in the Chinese enterprise software firm on 2 September. That is a concentrated personal bet on a single stock and stands out for its size alone.

Intel CEO Lip-Bu Tan filed a $10m open-market purchase on 14 August, covering a trade made on 11 August. Discretionary CEO buying at INTC carries real signal weight. Tan took the top job in early 2024 and has been vocal about a turnaround. Buying $10m of stock with his own money adds credibility to that case.

BSX Chairman and CEO Michael Mahoney filed a $9m purchase in Boston Scientific on 5 August, covering a trade three days earlier. C-suite buying in a large-cap medtech name with no 10b5-1 plan flag attached is a meaningful data point.

Savannah Energy CEO Andrew Knott filed an $11.8m buy in the Africa-focused energy group on 7 August. That is a sizeable personal stake increase for a smaller-cap name.

On the sell side, JPMorgan Chase reduced its 5%-plus positions in several Hong Kong-listed technology names including Kingdee International ($84.9m sold) and Sunny Optical ($70.8m sold), both filed on 8 September. These are institutional position adjustments rather than executive sentiment signals.
