On August 24, Lumentum fell 4.01% in pre-market trading, trading at approximately $828.58/share, with turnover of $5.20 million. The decline reflects continued sector-wide selling pressure in optical communication stocks.

The 30-year US Treasury yield has climbed to its highest level in nearly two decades, intensifying valuation headwinds for capital-intensive AI hardware names that are highly sensitive to discount rate changes. The rate surge, combined with growing concerns over an AI infrastructure spending bubble, has triggered a systematic correction across the optical communication sector. Peer Applied Optoelectronics dropped over 13%, underscoring broad industry weakness.

Despite Lumentum reporting significantly better-than-expected fiscal Q4 results on August 11 — with revenue surging 109% year-over-year to $1.03 billion and multiple investment banks raising target prices (JPMorgan to $1,280, BNP Paribas to $1,380, Citi to $1,200) — short-term sector rotation pressure remains unresolved. The upcoming Jackson Hole central bank symposium and core PCE data release represent key observation windows for potential near-term valuation recovery.
