Balakrishnan has sold in every month with a filing in 2025-2026, with individual blocks ranging from 3,000 to 10,000 shares at prices between $44 and $60.

What It Means

Power Integrations designs energy-efficient power conversion semiconductors used in consumer electronics, industrial equipment, and EV chargers. Balakrishnan's $179 million in career sales through nearly 2,000 transactions reflects the classic long-tenured CEO selling pattern — small, frequent blocks disposed through a 10b5-1 plan regardless of market conditions. The zero career purchases indicate his entire holding originates from compensation and founding-era equity.

With POWI trading around $47 — well below its 2021 peak near $100 — the continued selling at depressed levels suggests Balakrishnan's plan operates on a fixed schedule rather than being price-sensitive. This is a neutral signal: systematic sellers continue through both peaks and troughs.

What to Watch

• Whether Balakrishnan modifies or terminates his selling plan at current prices, which would be a notable change from two decades of consistency
• POWI's exposure to the EV charging and renewable energy markets, which represents the company's best growth catalyst
• Any insider buying from other POWI executives, which would contrast with Balakrishnan's sell-only record and signal internal conviction
