3 Growth Stocks to Buy and Hold for the Next Decade

Motley Fool spotlights three high-risk, long-horizon ideas: Oklo, a designer of compact fast‑neutron reactors aiming to power data centers (partners include Equinix and Vertiv) but still pre‑revenue and awaiting NRC licensing; Joby Aviation, an eVTOL air‑taxi developer targeting a potentially $1 trillion urban‑mobility market by 2040 (per Morgan Stanley) that must secure FAA certification and build infrastructure; and MP Materials, the owner of Mountain Pass producing rare‑earths and high‑performance magnets with strategic ties to Apple and U.S. government support and a joint venture with Saudi Arabia to expand refining. Each thesis rests on durable secular demand (AI power needs, new urban transport, reshoring critical minerals) but carries significant regulatory, execution and capital‑intensity risks—Oklo and Joby lack commercial revenue while MP is revenue‑generating yet loss‑making and must rapidly scale its 10X magnet facility—making them suitable only for aggressive, long‑term investors.

Analysis

Motley Fool highlights three high-risk, long-horizon ideas: Oklo (NYSE: OKLO), Joby Aviation (NYSE: JOBY) and MP Materials (NYSE: MP). Oklo is developing compact Aurora fast-neutron reactors to power data centers and has partnerships with Equinix and Vertiv but remains pre-revenue and is awaiting Nuclear Regulatory Commission (NRC) licensing to commercialize its design. Joby is building an eVTOL air-taxi targeting a Morgan Stanley-estimated $1 trillion urban-mobility market by 2040 but must secure Federal Aviation Administration (FAA) certification and create vertiports and charging infrastructure before scaling, and it also lacks meaningful commercial revenue. MP Materials operates the Mountain Pass rare-earth mine, produces high-performance magnets, counts Apple and U.S. government support among strategic partners, and has a joint venture with the Saudi Arabian Mining Company while generating revenue but reporting losses.

The investment cases rest on secular trends—AI-driven electricity demand and clean power for Oklo, new urban-transport demand for Joby, and reshoring critical minerals for MP—while the article and signals describe sentiment as mildly positive and speculative. Key near-term catalysts and risks are regulatory approvals (NRC, FAA), execution of infrastructure and factory builds, and the timing of MP’s 10X magnet-factory expansion; delays or cost overruns would meaningfully affect cash flow and share volatility. The author’s disclosure of positions and the Stock Advisor omission of Oklo underscore that these names require long timelines and substantial capital tolerance.

Financial implications include continued cash burn and potential equity dilution for Oklo and Joby until commercial revenue, and heavy capex that may pressure MP’s margins if the 10X Facility is delayed. Given these factors, the trio fits an aggressive, speculative allocation rather than core equity exposure, with monitoring focused on regulatory milestones, partnership contracts, and capital-raise activity.

Key Decisions for Investors

• Consider only a small, opportunistic allocation to Oklo and increase exposure incrementally only after clear NRC licensing milestones and binding commercial contracts with data-center operators are announced
• For Joby, wait for concrete FAA certification progress and demonstrable infrastructure commitments (vertiports/charging) before adding to positions, because certification and scale-up risk remain the dominant near-term threats
• Position MP Materials as a tactical core holding to play U.S. rare-earth reshoring given revenue generation and strategic partners, but size positions to reflect execution risk around the 10X Facility and hedge or trim on signs of construction delays or increased cash burn
• Monitor a short catalyst list—NRC and FAA approvals, MP’s 10X construction timeline, quarterly cash-burn and any equity raises—and be prepared to reduce exposure or hedge if regulatory setbacks or capital raises materially dilute value
