KNGZ seeks to mirror the performance of a US large-cap, sector-neutral index. This includes companies within the index that have a track record of consistently increasing or maintaining their dividends for at least 15 years, with a strong dividend yield compared to peers in the same industry. The fund invests in a diversified portfolio of securities selected based on their dividend history and yield, with sector weights adjusted to mirror that of the index. Securities are ranked and weighted within sectors based on their annualized dividend yield, with weighting constraints. If a sectors target weight is not met, additional securities may be selected based on their dividend yield history. KNGZ adjusts its holdings after annual index reconstitution, quarterly rebalancing, and monthly reviews. Prior to October 3, 2023, the fund tracked the Nasdaq Riskalyze US Large Cap Select Dividend Index, traded under the symbol RNDV and the name First Trust US Equity Dividend Select ETF.
