Lumentum Holdings Inc (LITE) shares fell 6.76% to $1028.72 on Monday. The decline followed a sharp rally in the prior week, during which the stock reached a 52-week high. The move appears to reflect profit-taking after a significant run-up, despite recent announcements regarding strong demand for the company’s optical components.
What Happened
Lumentum shares had surged 18.0% over the previous eight sessions, moving from $948.68 to $1119.21. This momentum was driven by reports that the company’s CEO stated components are sold out through early 2029, signaling robust demand for indium phosphide and silicon photonics suppliers. Wedbush analysts described this sold-out status as bullish for the supply chain. Additionally, Lumentum announced it will join Astera Labs and Corning at the 2026 OCP Global Summit to demonstrate a rack-level PCIe-over-optics proof-of-concept. The demonstration aims to show an error-free PCIe-5 link using multiple 32 Gb/s NRZ optical channels for AI rack-scale connectivity.
What The Data Shows
The stock opened at $1108.00, which was also its session high at 7:00 AM ET. It subsequently dropped to a session low of $1017.04 at 10:05 AM ET before closing near $1031.68. Trading volume was 1.1 million shares, which is 0.2 times the three-month daily average. The company remains unprofitable with a trailing twelve-month EPS of -$92.96 and a net margin of -230.1%, though revenue grew 83.2% year-over-year. The market capitalization stands at $99.9 billion. In the last 90 days, insiders filed 19 sales totaling $64.8 million, with no buys recorded. Recent sales include transactions by CFO Ali Wajid and President Wupen Yuen. Congressional disclosures show three buys and three sells in the same period, including purchases by Rep. Ro Khanna and Donald J. Trump. The stock printed 12 fresh 52-week lows on October 12, 2026, according to the 52-week tape data, while its 52-week range spans $147.81 to $1143.00.
What To Watch
With no scheduled earnings date provided in the current data, attention remains on the company’s ability to sustain its sold-out status through 2029 and the reception of its PCIe-over-optics demonstration at the upcoming OCP Global Summit.
