SpaceX is trading 3.12% down now at $149.99 amid a softer U.S. market and positioning ahead of the September 21 Nasdaq-100 rebalance.
- Its index weighting is expected to more than double, potentially attracting billions in passive buying.
- Available reporting does not establish that rebalance positioning directly caused the September 18 decline.
- Earlier Vietjet Starlink and launch-contract news remains supportive but does not explain today’s drop.
