The Invesco S&P Spin-Off ETF (CSD) aims to mirror the performance of the S&P U.S. Spin-Off Index. This fund commits at least 90% of its total investments to the stocks and depositary receipts that make up its benchmark index. The index itself consists of businesses that have separated from larger parent entities within the last four years. Its performance is measured using the gross total return, which fully incorporates all dividend payments. Both the ETF and its tracking index are adjusted on a monthly basis.
