These 2 Space Stocks Are Down 24% and 41%: Which Is the Better Buy Today?

Space stocks saw a large rotation-driven sell-off: Rocket Lab shares fell ~24% and Intuitive Machines dropped ~40.5% over the past month, with the article attributing moves mainly to the “SpaceX effect” and higher interest rates (long-duration discounting) rather than deterioration in fundamentals. For long-term investors, Rocket Lab is framed as the sturdier bet after a ~28% pullback, supported by diversified businesses, a growing backlog, and the upcoming Neutron rocket targeting a late-2026 first flight. Intuitive Machines is described as the higher-upside but higher-risk lunar play, given its heavy reliance on NASA contracts and mission execution risk.

Analysis

The main signal here is not operational deterioration but a tighter cost of capital for a subsector whose cash flows are still back-end loaded. That matters more for LUNR than RKLB because concentration plus mission risk creates a financing overhang: every delayed contract milestone or failed landing raises the probability of dilution at a worse valuation. By contrast, RKLB’s mixed revenue base should make it less sensitive to a single catalyst failure and more resilient if rates stay elevated.

Near term, the setup is still flow-driven, not fundamental. If the SpaceX listing continues to absorb incremental risk capital, public comps can stay depressed even with intact order books; that argues for relative value over outright beta. Over 1-3 months, the key falsifier for RKLB is any Neutron schedule slip or a backlog that fails to convert into launch cadence, while for LUNR it is any NASA budget/award pause or mission execution miss.

The contrarian point: the drawdown may be only partly overdone. The market is correctly pricing that these are long-duration equities, but may be underpricing how much private-market enthusiasm for SpaceX can structurally crowd public space names out of institutional portfolios. If yields roll over and Neutron hits the pad on time, RKLB can rerate faster than the market expects; if not, both names remain trading vehicles rather than durable fundamentals stories.

Key Decisions for Investors

• Long RKLB / short LUNR as a 1-3 month relative-value pair; express the cleaner balance between diversified revenue and mission concentration, with the spread thesis invalidated if RKLB misses Neutron timing or LUNR secures a catalyst-rich NASA re-rate.
• Buy RKLB on further weakness only after confirmation that Neutron launch prep remains on schedule; treat it as a starter position with a 6-12 month horizon, not a momentum chase.
• Avoid initiating new outright LUNR longs ahead of mission-critical events unless using small size; the risk/reward is dominated by execution binary and potential dilution, not cheapness.
• If using options, prefer RKLB call spreads over naked equity for the next 2-4 months to cap downside from launch slippage while retaining upside from a successful first-flight narrative.
