Insider selling remains directionally consistent with recent 30-day pattern totaling $10M, but dollar amounts are immaterial relative to $4.8B market cap. No C-suite participation limits signal value. Monitor the next quarterly filing for any fundamental deterioration — insider selling at this scale alone does not warrant a trade.
Price Chart
Executive Summary
Two directors sold $4.42M in open-market sales on May 26, 2026 — the total is ~0.09% of POWI's $4.8B market cap, just below the 0.1% materiality threshold. No C-suite selling is present, and the dollar magnitude relative to company size is trivial. Historical calibration on this ticker shows past neutral/score=2 calls underperformed (T+20 -4.81%), but that doesn't change the routine nature of this cluster.
