Rocket Lab Corporation (RKLB) shares dropped nearly 7% to $55.25, extending a seven-day losing streak that brought the stock close to one-year lows. The selloff came as the company postponed the debut flight of its reusable medium-lift Neutron rocket from late 2026 to 2027. Engineers discovered air pockets in a carbon-composite propellant dome for the rocket's first stage, requiring manufacturing adjustments and additional testing before a firm launch date can be set.

The Neutron delay overshadows recent positive developments, including ARK Investment Management purchasing $9.32 million worth of shares during the pullback across three exchange-traded funds. Additionally, equipment from the company's acquired subsidiaries helped power NASA's Perseverance rover as it set a record for driving 28.1 miles on Mars. However, investors remain focused on Neutron because the medium-lift rocket is crucial for expanding business into larger payloads and higher-revenue launch missions.

Looking ahead, market participants will watch for updates on the production and validation of a replacement forward dome for Neutron. Rocket Lab must successfully assemble and test the component to finalize its revised target launch schedule. Investors will also monitor whether institutional support, such as recent buying from ARK funds, can help stabilize the stock, which is down 21% year-to-date.
