The Invesco KBW Bank ETF, commonly known as "the Fund," is designed to mirror the performance of the KBW Nasdaq Bank Index, or "the Index." Typically, the Fund commits at least 90% of its total assets to the equities comprising this benchmark. The Index itself employs a modified market capitalization-weighting methodology, concentrating on corporations primarily involved in the U.S. banking sector. Its development, upkeep, and calculation are a collaborative effort by Keefe, Bruyette & Woods, Inc. and Nasdaq, Inc. The Index's constituents include prominent national U.S. money center banks, regional banking establishments, and thrift institutions whose shares are publicly traded in the United States. Both the Fund and the Index undergo adjustments to their holdings and composition every quarter.
