$LYTE Roundhill Photonics & Optics ETF
Roundhill · launched August 6, 2026 (2 months ago)
What LYTE is
The Roundhill Photonics & Optics ETF focuses on the optical side of the AI infrastructure build: optical interconnects, lasers and photonic chips that move data with light inside AI data centers. At launch its top holdings included Lumentum, Coherent, Ciena and Fabrinet, plus China-listed optical module makers such as Eoptolink and Zhongji Innolight.
Worth knowing
A concentrated top ten and a large weight in China-listed optical module makers mean LYTE can move very differently from a broad semiconductor fund. Position sizes can change quickly in an actively managed fund.
