Cramer’s Cautious View on Space Stocks
Investment interest in the commercial space and defense sectors remains robust, but CNBC’s Jim Cramer expressed caution about high-risk options, especially Rocket Lab Corporation (NASDAQ:RKLB). On August 5, when questioned about Rocket Lab, Cramer dismissed it as a speculative investment and directed investors to Voyager Technologies, Inc. (NYSE:VOYG).
Cramer’s endorsement of Voyager Technologies comes following its impressive Q2 earnings, which he analyzed during an August 4 episode. He emphasized Voyager’s significant growth in government defense contracts, marking a 51% revenue increase compared to the previous quarter and a notable 22% rise in backlog. Management pointed out that demand in the defense and space sectors is growing rapidly, outpacing their ability to convert that demand into revenue. Voyager’s performance was bolstered by its recent acquisition of Astrobotic, a company focused on space robotics. Following the earnings report, Voyager’s stock saw a spike, jumping 14% immediately and rising an additional 19.6% the following day, although it remains down approximately 55% from its peak last summer.
Investor sentiment is shifting, as demonstrated by the data from Insider Monkey. Hedge fund ownership in Rocket Lab decreased from 45 holders in Q4 2025 to 43 in Q1 2026, while Voyager saw an increase in hedge fund backing, rising from 35 to 37 holders in the same time frame.
Market evaluation further contrasts the two companies. Rocket Lab trades at an elevated price-to-sales ratio of 53.10 with short interest at 7.97%, indicating some bearish sentiment among investors. In contrast, Voyager’s price-to-sales ratio of 8.67 is significantly lower, though it faces a higher short interest of 21.65%, pointing to increased scrutiny despite its positive growth trajectory.
The financial dynamics between the two firms underline the operational contrasts: Rocket Lab is heavily investing in its Neutron rocket program, while Voyager is effectively converting its defense sector demand into tangible revenue gains. With a 51% surge in revenue and a solid backlog growth, Voyager appears to offer the operational momentum that Cramer favors over more speculative ventures like Rocket Lab.
Although both Rocket Lab and Voyager Technologies present investment opportunities, various analysts suggest that certain AI stocks might offer more favorable risk-reward profiles. Investors are advised to evaluate all options before making investment decisions.
