Rocket Lab stock fell 6.64% to $55.25 on October 15, 2026. The primary driver was the company’s announcement that it is delaying the inaugural flight of its Neutron rocket to 2027. This decision shifted investor focus toward manufacturing progress and flight cadence, contributing to a broader sell-off in the space sector.
What Happened
Rocket Lab delayed the debut flight of its Neutron medium-lift rocket, which was intended to rival SpaceX’s Falcon 9. The delay follows the discovery of a defect in the rocket, prompting engineering rework. The company maintains a backlog of $2.4 billion, but the slip in the launch timeline has increased execution risk for investors. KeyBanc lowered its price target on RKLB shares to $100 while maintaining an Overweight rating. TD Cowen reiterated its Buy rating with a $90 price target. The move occurred against a backdrop of rate-hike fears that weighed on semiconductor stocks, with Rocket Lab listed among the companies making significant midday moves.
What The Data Shows
The stock opened at $53.06, a 10.3% gap down from the prior close of $59.18. The session low was $49.69 at 9:55 AM ET, while the session high reached $56.32 at 4:35 PM ET. Volume totaled 38.3 million shares, which is 1.8 times the three-month daily average. Over the last eight sessions, the stock has declined 29.9%, moving from $75.06 to $52.64. The 52-week range is $37.57 to $151.00, with the stock printing 11 fresh 52-week lows on October 15. Unusual options activity included 28 notable prints, with put premium of $40.0 million significantly exceeding call premium of $10.7 million. The largest single print was $12.4 million. Insider filings over the last 90 days show nine sells totaling $27.0 million, with no buys. The most recent insider sale was by CFO Adam C. Spice on October 2, 2026.
What To Watch
Investors will monitor the company’s progress on Neutron manufacturing and its ability to convert its backlog into revenue. The stock’s high beta of 2.94 suggests continued volatility as the market digests the launch timeline shift.
