| Factors Affecting Performance [Text Block] | How did the Fund perform since inception? What affected the Fund’s performance? Performance Highlights • The Nuveen Preferred and Income ETF returned 4.05% for Common Shares at net asset value (NAV) for the abbreviated reporting period since the Fund’s inception on March 5, 2024, through July 31, 2024. The Fund underperformed the NPFI Blended Benchmark, which returned 4.61%. The NPFI Blended Benchmark consists of: 60% ICE US Institutional Capital Securities Index (IIPS), and 40% ICE USD Contingent Capital Index (CDLR). • Top contributors to relative performance » Security selection within fixed-to-fixed rate coupon securities, particularly recently issued, higher coupon securities, which outperformed the broader preferred securities market. • Top detractors from relative performance » Shorter-duration positioning, resulting from an overweight to floating-rate coupon securities, which detracted as short-term rates decreased during the reporting period. » Underweight to contingent capital securities (CoCos), which was partially offset by favorable security selection within that segment.
