New York, Jan 7, 2026, 16:55 EST — After-hours
- Rocket Lab shares fell 2.2% in regular trade after an executive stock sale disclosure
- SEC filing showed the COO sold 100,000 shares under a pre-set trading plan
- Investors now eye the next earnings update and any Neutron timeline signals
Rocket Lab Corp shares closed down 2.2% at $84.16 on Wednesday, after swinging between $81.85 and $85.96 as investors digested an insider sale after a sharp run-up earlier this week. 1
The pullback matters because Rocket Lab has become a crowded trade in space-and-defense stocks, where price moves have been fast and explanations thin. After a big early-January jump, traders have been quick to treat insider selling as a check on momentum, even when it is routine.
A filing with the U.S. Securities and Exchange Commission showed Chief Operating Officer Frank Klein sold 100,000 shares on Jan. 2 at weighted average prices from $67.61 to $75.80, for proceeds of about $7.3 million. The filing said the sales were made under a Rule 10b5-1 plan — a pre-arranged trading plan companies use to reduce the risk of trading on inside information — and that Klein held 1,169,487 shares after the transactions. 2
The broader tape was mixed. The S&P 500 slipped 0.3% and the Dow fell 0.9% on Wednesday, while the Nasdaq edged higher, leaving some high-beta names without much index help. 3
Rocket Lab’s stock has been buoyed in recent weeks by defense-related optimism, including a Space Development Agency award the company disclosed in December. In an 8-K, Rocket Lab said the SDA contract has a total value of $816 million, including a $806 million base amount and options of about $10 million, with final delivery of the satellites expected in 2029. 4
Still, there’s a simple risk case: insider selling can persist, and contract work and rocket development do not always land on clean schedules. Any slip in major program milestones — or signs costs are rising faster than revenue — can hit a stock that has been trading near recent highs.
What’s next is the calendar. Rocket Lab is expected to report results on Feb. 26, according to Nasdaq’s earnings schedule, and investors will listen for updates on margins, backlog conversion and any shifts in timelines for its next-generation Neutron rocket. 5
