Here’s a detailed look at FOTO, which is probably the smallest asset management ETF in the U.S. stock market right now (only 3 trading days since listing, with a $500K management scale). But it’s also the most focused high-beta thematic portfolio in the U.S. market, centered on the photonic and optical interconnect industry chain. FOTO’s advantage lies in its highly focused theme: its holdings are all core industry chain companies related to AI data center optical modules, coherent optical communication, lasers, optical manufacturing, and testing & measurement. On the other hand, EUV leans more toward large-cap semiconductors + optics (its optical interconnect and optical purity are not as strong as FOTO). #ETF #FOTO #AI #Photonics #光互连 #美股
