$EUV vs $FOTO

The Corgi Lithography & Semiconductor Photonics ETF takes a wider angle on photonics, centered on lithography and chipmaking: the light-based tools that print chips, the equipment makers around them and the foundries that use them. Large positions have included ASML, TSMC, Applied Materials, Lam Research and KLA. Because it leans on large semiconductor equipment and foundry names, EUV behaves more like a chip-equipment fund than a pure optical networking fund. That can make it steadier than the pure plays, but it is a different bet.

The Tuttle Capital Pure Play Photonics ETF targets companies whose business is built around photonics: optical components, lasers, optical networking gear and the manufacturers behind them. Recent holdings have included names such as Lumentum, Coherent, Ciena, IPG Photonics and Fabrinet. FOTO gets part of its exposure through total return swaps and holds a meaningful slice of cash and Treasury bills alongside those swaps, so its holdings list looks different from a plain stock basket.

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.
