On June 16, Rocket Lab USA declined 3.21% in regular trading, trading at $105.39/share, with turnover of $439 million. The pullback follows a sharp rally of approximately 8% in the prior session.

On the news front, the decline reflects profit-taking pressure after Rocket Lab surged on June 15 driven by its upcoming inclusion in the Nasdaq-100 Index (effective June 22) and a sector-wide oversold rebound. The broader commercial space sector continues to face a capital siphon effect following SpaceX's blockbuster IPO on June 12, which saw shares surge nearly 19% on debut and pushed SpaceX's market capitalization past $2.1 trillion. Within the Aerospace & Defense sector, Redwire fell 5.46% and Intuitive Machines dropped 5.94%, while traditional defense names GE Aerospace and Howmet Aerospace rose 2.74% and 2.28% respectively, underscoring ongoing sector divergence.

Despite KeyBanc upgrading Rocket Lab to Overweight with a $135 target price, short-term technical selling pressure after the prior session's gains appears to dominate sentiment as investors digest the SpaceX-driven sector rotation.
