A report shows that as of September 4, executives and directors at NVIDIA, Palantir, and Meta Platforms have net sold approximately $18.6 billion worth of company stock over the past five years, while insider buying has almost stalled during the same period. Specifically, NVIDIA saw net insider sales of $6.31 billion, Palantir $6.63 billion, and Meta $5.69 billion. Analysts suggest that while executive stock sales may be for tax reasons, the lack of insider buying could signal a lack of confidence in future stock price appreciation.
