On September 21, SpaceX rose 3.28% in regular trading, trading at $157.925/share, with turnover of $3.948 billion. The rally was driven by two key catalysts: the Nasdaq 100 quarterly rebalancing took effect before today's open, and Morgan Stanley reiterated a bullish outlook with a $300 price target.

The Nasdaq 100 rebalancing raised SpaceX's index weight from approximately 1.28% to 2.82%, more than doubling its representation. The previous underweight stemmed from most shares being in lock-up when SpaceX was added to the index in July. Over 200 investment products globally track the Nasdaq 100 with combined assets exceeding $800 billion, meaning passive funds and ETFs — including the $482 billion Invesco QQQ Trust — must now increase SpaceX allocations, triggering billions of dollars in mechanical buying.

Separately, Morgan Stanley analyst Adam Jonas reiterated an Overweight rating and $300 target price, characterizing SpaceX as a defensive play amid AI sector volatility. The firm highlighted Starlink's expanding enterprise and government client base as a cash-flow moat, along with SpaceX's investment-grade credit ratings and a recently completed $20 billion note issuance. The analyst noted that orbital AI and long-term growth optionality remain effectively unpriced by the market.
