$EUVX vs $LYTE

The short version

EUVX is cheaper to own, at 0.45% a year versus 0.65%. LYTE is the bigger fund, with $343M in assets. EUVX has been around longer, launching on June 3, 2026.

EUVX

The Corgi Lithography & Semiconductor Photonics 2x Daily ETF aims for twice the daily move of its lithography and semiconductor photonics strategy. Leveraged ETFs reset every day. Over periods longer than a day, returns can differ a lot from 2x the underlying move, especially in choppy markets. These are trading tools, not long-term holdings for most investors.

LYTE

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. 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.

Lower fees and more assets are helpful, but they are not the whole story. The bigger question is which strategy matches what you want to own. This comparison is not a recommendation to buy or sell either fund.
