Broadcom (AVGO) shares dropped nearly 5% in pre-market trading despite the company reporting robust fourth-quarter earnings. The semiconductor giant posted revenue of $18.015 billion and an adjusted earnings per share (EPS) of $1.95, both surpassing analyst expectations. CEO Hock Tan highlighted concerns over AI-related margin pressures and revealed a $730 billion order backlog spanning six quarters, which may have contributed to the market's cautious response. The shift in investor sentiment was evident as enthusiasm waned following Tan's remarks.
