SpaceX Stock and the Nasdaq-100: What History Tells Us About Potential Returns After July 7

SpaceX was added to the Nasdaq-100 on July 7, 2026. While index inclusion typically drives buying activity, historical data shows that over the past two years, only 6 of 21 companies added to the index gained in their first week, with an average loss of 3.8%. However, stocks showed more promise longer-term, averaging 3.6% gains after one month and 6.3% after three months. Long-term returns will depend on SpaceX's execution in capturing its $26.5 trillion addressable market in AI infrastructure.
