I focus on semiconductor ETF portfolio construction, with particular attention to how different funds allocate capital across chip designers, foundries, memory manufacturers, equipment suppliers, and other semiconductor businesses. I publish on this website because an ETF name does not always reveal the actual exposure inside the portfolio. Two products described as semiconductor funds may have very different concentrations, geographic allocations, company sizes, and sector weightings. My research examines portfolio concentration, top holdings, rebalancing, geographic exposure, market capitalization, and sector diversification. I also study how index rules influence the final composition of an ETF. Another area of my work is comparing broad semiconductor ETFs with targeted products focused on equipment, memory, AI computing, or other subsectors. I believe understanding portfolio construction is essential when analyzing the practical exposure of an ETF. My goal is to help readers look beyond ETF labels and understand the actual companies, sectors, and market factors represented within semiconductor funds.
