Apple Inc.Index funds must trim Apple holdings to buy SpaceX, causing forced selling.
The Nasdaq-100 and Russell 1000 indexes changed their rules to fast-track the inclusion of Space Exploration Technologies after its June IPO, forcing index funds and ETFs that track these benchmarks to buy the stock and trim holdings in giants like Apple, Microsoft, and Nvidia. The S&P 500 chose not to alter its rules, leaving its index funds without SpaceX exposure. The rule changes concentrate forced buying into a short window, shifting sector weights and risk profiles for millions of passive investors. SpaceX's volatile debut highlights how mega IPOs can reshape portfolios even for those who do not directly own the new stock.
