Lumentum Holdings claimed the top spot among S&P 500 performers Monday as optical technology stocks staged a broad comeback, driven in part by fresh momentum in the artificial intelligence infrastructure space.
Anthropic's IPO filing served as a key catalyst for the rally, signaling continued investor appetite for AI-related investment and the underlying hardware that supports large-scale AI computing — a segment where optical component makers play a critical role in high-speed data transmission.
