By contributing portfolios in kind to registered investment companies, investors receive ETF shares without triggering immediate tax events, potentially reshaping future inflows across broad-market funds like SPY.
2. May Inflation Spurs S&P 500 Decline
US consumer price index rose 0.5% month-over-month and 4.2% year-over-year in May, driven by energy and shelter costs. The S&P 500 fell 1.3% on the day, erasing recent gains as market pricing assigns a 98% probability of a Fed rate hold on June 17 and a roughly 25-basis-point hike by December, pressuring SPY valuations.
