Coin Bureau’s DC says insiders at Nvidia, Broadcom, Arista and CoreWeave sold over $2 billion on the open market since June. He attributes about $1.35 billion to Nvidia director Mark Stevens and $500 million to Broadcom chairman Henry Samueli. DC treats the concentration and scarcity of insider purchases as warning signs, while acknowledging routine diversification, tax and estate planning. He explains that 10b5-1 plans can arrange sales months ahead and distinguishes genuine sales from gifts and tax withholding, so headline totals alone do not establish sellers’ motives.
