Making the Case for Space: 4 Small Stocks That Are Packing a Big Punch

- Navigating the final frontier: Small-cap space stocks offer explosive growth potential as the space economy expands.

- From satellites to space-based internet: Discover the small companies leading the charge in the space revolution.

- Space ETFs, small caps, and the future of innovation: Why these four under-the-radar stocks deserve attention.

 

Background: The Growing Space Economy

Over the past decade, the space industry has evolved from a government-dominated arena into a thriving private sector brimming with opportunity. In 2022, the global space economy surpassed $469 billion, and analysts expect it to soar past $1 trillion by 2040. This explosive growth is driven by advances in satellite technology, space exploration, and emerging industries like space tourism and orbital infrastructure.

Small-cap companies, often overlooked in favor of larger players, are spearheading much of this innovation. These nimble companies are carving out their own niches in areas such as satellite communications, lunar exploration, and in-space services. While they carry more risk, their potential for rapid growth makes them attractive to investors seeking exposure to the space industry.

Investors can get diversified exposure to these small and mid-sized space companies through the NASDAQ: UFO ETF, which focuses on space-related businesses, or through NYSE: IWM, the Russell 2000 ETF which tracks a broader range of small-cap stocks, many of which are at the forefront of this space revolution. For those looking to invest in the next frontier of technology and exploration, small-cap space stocks represent an opportunity to capture the future growth of the space economy while taking calculated risks in this high-potential sector.

Background:

Spire Global is a satellite data company specializing in gathering global data from space to provide insights for weather forecasting, ship tracking, aircraft monitoring, and more. Founded in 2012, Spire has positioned itself as a leader in small-satellite data analytics, operating one of the world’s largest fleets of low Earth orbit (LEO) satellites. Spire’s data services are critical for industries like maritime, aviation, and defense.

Recent News:

In early 2024, Spire announced a significant partnership with NASA, where its satellites will be used for data collection in support of the agency’s Earth observation missions. Additionally, the company’s continued expansion into the maritime and aviation markets shows its growing importance as a data provider. Spire is working with several major organizations to enhance climate monitoring and commercial weather forecasting capabilities.

Performance: 

Spire Global’s stock performance has been volatile over the past few months, reflecting both the challenges and opportunities within the small satellite data industry. Over the past three months, SPIR has seen a modest decline, shedding around 11% due to broader market headwinds. 

Investment Thesis:

Spire offers a unique opportunity for investors seeking exposure to the data economy from space. Its LEO satellite network is well-established, with diverse revenue streams coming from government contracts, weather forecasting, and logistics. Although its small-cap status makes it volatile, Spire’s long-term growth potential remains promising as industries become increasingly reliant on real-time, space-based data.

Furthermore, AST is working closely with major telecom players like Vodafone and AT&T to bring its service to market over the coming years.

Performance: 

AST SpaceMobile made headlines not only for its groundbreaking technology but also for its exceptional stock performance. In a rare feat, ASTS skyrocketed from a small-cap stock to briefly entering large-cap territory, skipping over mid-cap status entirely when its stock hit $38. This surge occurred over a few short months, highlighting the company’s potential and the market’s excitement around its space-based cellular network. Despite some pullback, ASTS is still up a whopping 518% in the past three months and maintains significant year-over-year gains (+773%), reflecting its unique position in the telecommunications market.

Investment Thesis:

AST SpaceMobile presents a high-risk, high-reward investment opportunity. While still in the developmental phase, the company’s successful technological demonstrations and partnerships with major telecom companies offer significant upside potential. If ASTS can scale its network, it could become a disruptive force in the $1.3 trillion global telecom industry, offering exposure to a technology that could connect billions of people to the internet for the first time.

Investment Thesis:

With its focus on lunar infrastructure, Intuitive Machines is positioned to benefit from the increasing interest in Moon exploration. The company is a key player in NASA’s Artemis program, and as the space agency ramps up its lunar missions, LUNR is well-placed to secure additional contracts. For investors, this company offers exposure to a burgeoning area of the space economy that could expand rapidly as lunar exploration and infrastructure develop.
