Power Integrations insider Balu Balakrishnan sold 95,287 shares on May 28, 2026 at $86.25 per share, a transaction worth about $8.22 million. By dollar value, this is the largest reported insider trade at the company in the past 30 days, making it a notable reduction in exposure by a key company insider. Insider selling can draw attention because it represents an executive or closely connected person choosing to cash out shares at current prices. Balakrishnan’s role as an insider matters because insiders typically have a deeper view of the business than outside investors, even though sales can occur for many non-business reasons such as diversification, taxes, or planned selling programs. This trade also comes amid a cluster of recent insider sales at POWI. Balakrishnan sold another $3.87 million on May 26, and other insiders sold shares as well, including Sunil Gupta ($1.31 million on May 26) and Nicholas Brathwaite (about $550,000 on May 26 and about $150,000 on May 27). The concentration of selling over a short period is a pattern investors often monitor alongside upcoming earnings, guidance updates, and changes in company fundamentals.
