📝 Executive Summary
SpaceX (SPCX) is set to receive an estimated $15.5 billion in passive inflows on September 21 as its weighting in the Nasdaq-100 index increases from 1.25% to 2.25%. While this rebalancing provides a technical tailwind, investors face potential volatility from upcoming lock-up expirations that could release over 2.3 billion shares into the market by November.
