The Columbia High Dividend Premium Income ETF is an actively managed exchange-traded fund that seeks to provide high income, with capital appreciation as a secondary objective. The fund invests primarily in dividend-paying common and preferred stocks and employs a covered call strategy by writing call options on U.S. equity market indexes while purchasing call options to retain some upside potential. Designed to generate high monthly income from option premiums, the strategy may also offer favorable tax treatment through the use of certain index options.
