Cramer’s Caution on Space Stocks: **Rocket Lab** vs. **Voyager Technologies**

Mad Money’s outspoken host Jim Cramer took a measured stance on August 5 regarding space and defense equities.

Cramer’s Take on Space Stocks

Cramer dismissed Rocket Lab (RKLB) as “pure speculation” and steered investors toward Voyager Technologies (VOYG). His warning underscores the contrast between high volatility and long‑term value creation potential.

Voyager Technologies’ Quarterly Performance

The company reported a 51% sequential revenue increase, posted a narrower‑than‑expected loss, and saw its stock jump 14% before earnings followed by an additional 19.6% rally. Management highlighted demand outpacing production capacity and substantially raised its full‑year revenue outlook, partially driven by the Astrobotic acquisition.

Hedge‑Fund Ownership and Valuation Metrics

■Rocket Lab (RKLB): price‑to‑sales 53.10, short interest 7.97%; elite hedge‑fund holders fell from 45 in Q4 2025 to 43 in Q1 2026.

■Voyager Technologies (VOYG): price‑to‑sales 8.67, short interest 21.65%; hedge‑fund holders rose from 35 to 37 over the same period.

Market Reaction and Risk Assessment

Cramer’s commentary suggests Voyager offers a more attractive risk‑on opportunity given its lower valuation and growing institutional interest, though the elevated short‑seller presence signals potential price pressure.

■Voyager benefits from robust government contracts and a rising backlog that should sustain future cash flows.

■Rocket Lab’s lofty valuation reflects speculative expectations while institutional backing wanes.

■Heavy short‑selling on Voyager could create downside price pressure.

■Investors should align positions with prevailing risk‑on/off cycles.

Bora Yalın – Senior Researcher, International Capital Flows: Cramer’s guidance points to a sensible tilt toward Voyager Technologies amid current market turbulence. Yet the high short‑interest and Rocket Lab’s steep P/S multiple warn of speculative pull‑backs. Portfolio diversification and liquidity monitoring remain paramount, especially in risk‑off environments.
