On August 24, Lumentum declined 5.7% in regular trading, trading at approximately $811.8/share, with turnover of $288 million. The stock extended losses from pre-market and overnight sessions amid a broad-based selloff in the optical communications sector.

On the news front, the 30-year US Treasury yield surged to its highest level since 2007, exerting significant valuation pressure on high-capex AI hardware names that are particularly sensitive to discount rate movements. Concerns over an AI infrastructure spending bubble further triggered systematic rotation out of the sector. Peer Applied Optoelectronics plunged over 15%, while Ciena fell more than 5%, reflecting widespread industry weakness.

Despite Lumentum reporting blowout 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 maintaining Buy at $1,200) — near-term sector rotation pressure has overwhelmed fundamental support. The upcoming Jackson Hole central bank symposium and core PCE data release next week are viewed as key catalysts for potential valuation recovery.
