SpaceX shares drop after joining the Nasdaq-100 index

Shares in SpaceX fell on Tuesday as the Elon Musk-led company joined the Nasdaq-100 index, less than a month after its stock market debut on June 12. Inclusion in the tech-heavy index means SpaceX shares will be automatically bought by funds tracking the Nasdaq-100. Despite the share price slide, the milestone marks a significant moment for the space company's public market journey.
