Joby Aviation Plunges 2.54 as Regulatory Delays Weigh on eVTOL Sector Ranks 188th in $510M Trading Volume

On September 3, 2025, Joby Aviation (JOBY) closed with a 2.54% decline, trading at a volume of $510 million, ranking 188th among stocks by trading activity. The shares underperformed amid a broader market downturn but remained within a tight price range for the session.

Analysts highlighted muted investor sentiment toward the electric vertical takeoff and landing (eVTOL) sector following recent regulatory delays. A key development involved the Federal Aviation Administration’s (FAA) extended timeline for finalizing certification standards, which investors interpreted as a potential obstacle for Joby’s projected 2025 commercial launch. While the company has maintained its long-term product roadmap, the regulatory uncertainty weighed on short-term confidence.

Market participants also noted reduced liquidity in the stock compared to its 2024 trading pattern, with the volume declining from an average of $750 million to $510 million. This contraction coincided with the expiration of several key options contracts, suggesting a shift in institutional positioning. However, no material operational updates or earnings reports were released to trigger the decline.

Backtesting of the stock’s recent performance revealed that JOBY’s 52-week high of $12.45 remains intact, with support levels holding above $9.50. The price action has remained within a defined consolidation pattern since late July, reflecting ongoing indecision among traders regarding the sector’s valuation trajectory.
