On August 17, Lumentum rose 3.31% in regular trading, trading at $951.07/share, with turnover of $337 million. The stock extended its post-earnings rally as investor confidence in AI-driven optical demand persisted.

The upward move follows Lumentum's fiscal Q4 results reported on August 11, which delivered revenue of $1.01 billion (up 109% YoY), adjusted EPS of $3.23 (up 267% YoY), and non-GAAP gross margin of 50.4%, all exceeding consensus estimates. The Q1 guidance of $1.225-$1.275 billion in revenue came in approximately 8% above market expectations, with OCS revenue projected to meaningfully exceed $100 million. After an initial 14% surge on earnings day, a brief pullback driven by Bank of America lowering its target to $1,000, and a subsequent rebound, the stock continues to trade higher supported by broad optical communication sector strength and multiple analyst upgrades including Citi maintaining a Buy rating with a $1,200 target and BNP Paribas raising its target to $1,380.
