Nvidia Insiders Lead $4.6B Net-Selling Spree in AI Trio Amid Soaring P/S Ratios

Motley Fool reports escalating concerns over heavy insider net-selling at AI leaders Nvidia (NVDA.OQ), Palantir (PLTR.OQ), and Broadcom (AVGO.OQ), totaling roughly $4.6 billion over the trailing 12 months through April 28, 2026. Nvidia accounts for $2.40 billion in sales with zero purchases, while Palantir and Broadcom saw minimal buying ($3.3M and $1.6M respectively). Trailing P/S ratios stand at 24 for Nvidia, 28 for Broadcom, and 81 for Palantir, signaling historically rich valuations that could dampen enthusiasm and heighten volatility for these stocks, especially NVDA at $198.61 with $4.8T market cap.
