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

Space stock sell-off accelerates on “SpaceX effect” rotation plus higher interest rates: Rocket Lab shares fell ~24% and Intuitive Machines dropped ~40.5% over the past month. The article argues Rocket Lab looks more resilient due to diversified revenue, rising backlog, and Neutron (targeting a first flight late this year, with a multilaunch deal), but notes Neutron launch slip risk. Intuitive Machines offers higher upside on lunar mission success but is riskier given heavy NASA reliance and execution sensitivity.

Analysis

This is a valuation-duration event more than a fundamental reset. When rates back up, the market tends to punish the most capital-intensive, story-heavy names first, even if operating trends are intact; that makes the current move more about multiple compression than earnings revision risk. The implication is that the sector can snap back quickly if yields stabilize, but the rebound will likely be uneven: diversified revenue and nearer-term cash conversion should outperform single-mission platforms.

RKLB is the cleaner beneficiary because it has a path to self-funding from multiple lines of business, which lowers dependence on a single launch outcome and makes the equity less fragile to schedule slippage. LUNR has more torque but also a harsher downside skew: its equity behaves like a levered call on mission success plus government appropriations, so any budget wobble, launch anomaly, or slip in NASA timing can erase months of upside in one print. The second-order effect is that suppliers and adjacent small-space contractors tied to launch cadence should see valuation spillover only if RKLB proves it can industrialize Neutron without repeated delays.

Contrarian read: the market may be overpricing the permanence of the private-space halo. A blockbuster private listing only matters if public comparables remain the easiest liquidity outlet; if growth rates compress or the new private asset is not truly liquid, the rotation can reverse fast. For the next 1-3 months, the key catalysts are rate moves, any Neutron schedule commentary, and whether NASA funding headlines stabilize. Over 6-18 months, the real differentiator is which company can turn backlog into recurring gross profit without continual capital raises.

Key Decisions for Investors

• Long RKLB / short LUNR as a 1-3 month pair trade; thesis is lower execution risk and better revenue diversification. Use a modest gross size and stop the pair if RKLB announces a material Neutron delay or LUNR secures a visible budget/cash-flow upgrade.
• Buy RKLB only on weakness, not after a relief bounce; prefer a 2-4 month horizon into the next Neutron catalyst. Risk/reward improves if the stock discounts another schedule slip, but the thesis is invalidated by repeated launch deferrals or signs backlog is not converting.
• Avoid initiating fresh long exposure in LUNR unless there is confirmed NASA funding continuity or a mission success print. Treat it as a small speculative position only; otherwise the stock remains a negative-carry instrument when rates are firm.
• Set a watch item on UST yields and small-cap growth multiples: if real yields roll over, expect a sector beta rebound that could lift both names, with RKLB likely outperforming first. If yields stay elevated, keep exposure limited and favor hedged structures.
