Joby Aviation (JOBY) shows strong technological progress with certifications and partnerships, including a recent deal with Delta Airlines and participation in a White House pilot program. The company has achieved significant flight milestones, demonstrating operational readiness for commercial eVTOL services. However, the stock is highly volatile, with a beta of 2.53, and its financial performance still shows significant losses and cash burn. Analyst ratings are mixed, with a current consensus of 'Hold,' and the stock's long-term success hinges on proving demand, achieving profitability, and navigating regulatory hurdles. While the technology and execution appear strong, the business model and market adoption remain unproven.
