Lumentum stock plunges 10% despite full order book through 2029 amid optics sector selloff

Lumentum's stock dropped 10%, leading a broader 7% selloff in AI optics stocks like Applied Optoelectronics and Coherent, despite having a fully booked order book through early 2029. This decline highlights a sector-wide selloff rather than company-specific issues, as demand remains strong and capacity is sold out. Lumentum's high valuation and recent price surge likely contributed to the sharp pullback. Investors should watch if Lumentum can convert its booked orders into revenue as guided, with current-quarter revenue expected between $1.225 billion and $1.275 billion.

As of Oct 13, 2026 00:02 WIB, Lumentum (LITE) shares are trading at USD 987.99 on Pluang, down 10.46% for the day, closely matching the reported selloff. Applied Optoelectronics (AAOI) and Coherent (COHR) also declined on Pluang by 8.42% and 8.82% respectively, with AAOI priced at USD 100.41 and COHR at USD 285.04. The sector's sharp drop is reflected in these significant losses, with Lumentum's market cap near $99.95 billion standing out as the largest among them.
