SOXQ is a concentrated portfolio that provides capped exposure to the 30 largest US-listed companies involved in the design, distribution, manufacturing and sale of semiconductors. It might be worth noting that the fund has a slightly broader definition of the US semiconductor industry—its selection universe also includes foreign companies with ADR listings. To be eligible for the index, companies must meet investability and liquidity requirements, including a minimum market-cap of $100 million. SOXQ’s index employs a modified market-cap-weighting scheme, which caps weights of the top five securities at 8% and the remaining securities at 4%. The index is reconstituted annually and rebalances on a quarterly basis.
