On October 15, Lumentum fell 3.38% in Pre-Market Trading to $866.08 per share, with turnover of $10.877 million.

The main catalyst cited by recent market coverage is continued profit-taking and a broader pullback across optical networking and communication equipment stocks, even after the company said AI server optical component orders are sold out into early 2029 and that roughly 70% of demand for some products before 2027 still cannot be met.

Recent reports noted Lumentum had posted 83% revenue growth over the past 12 months and the stock had previously surged more than 556%, while peers including Applied Optoelectronics, Ciena, Arista Networks and Nokia also weakened, pointing to sector-wide pressure outweighing supportive target-price increases such as BNP Paribas raising its target to $1,425.
