    SpaceX IPO Forces Nasdaq-100 Rebalancing; Index Funds Trim Apple and Microsoft

    Question

    SpaceX IPO Forces Nasdaq-100 Rebalancing; Index Funds Trim Apple and Microsoft

    Direct answer

    The inclusion of SpaceX into major indices so soon after its IPO is creating a liquidity vacuum for other mega-cap names. Because index funds must maintain target weights, the multi-billion dollar entry of SpaceX requires a proportional exit from the largest holdings like Apple and Microsoft. This technical selling comes at a time when SpaceX itself is struggling to find a floor, trading below its $135 offering price as analysts debate its $1.5 trillion valuation.
