HACK is the first cybersecurity ETF on the market. The fund follows the ISE Cyber Security Industry classification and splits the industry into two segments: developers of cybersecurity hardware or software and providers of cybersecurity services. To be eligible for inclusion, a company must meet minimum market capitalization and liquidity screens. Eligible stocks must also derive at least 90% of their revenues from cybersecurity and should score at least 1.25% in revenue contribution. The resulting portfolio is market cap-weighted, subject to a weight capping methodology. The index is reconstituted and rebalanced quarterly. Before January 29, 2024, HACK traded under the brand name ETFMG and tracked the Prime Cyber Defense Index.
