Joby Aviation’s 18.82% Surge Drives $1.63B Volume Ranking 40th in Market Activity After Acquiring Blade’s UAM Passenger Business

On August 4, 2025, Joby Aviation (JOBY) surged 18.82% with a trading volume of $1.63 billion, a 105.85% increase from the previous day, ranking 40th in market activity. The stock’s strong performance followed its announcement of acquiring Blade Air Mobility’s urban air mobility passenger business for up to $125 million. The deal provides Joby with 12 key terminals in New York City and Southern Europe, including JFK and Newark airports, as well as a loyal customer base of over 50,000 passengers from 2024. Blade’s operations will continue under its founder Rob Wiesenthal as a wholly-owned subsidiary, enabling Joby to leverage existing infrastructure and reduce customer acquisition costs.

The acquisition accelerates Joby’s commercialization plans, particularly ahead of its planned passenger service launch in Dubai next year. By integrating Blade’s decade of premium transportation expertise with its electric aircraft technology, Joby aims to streamline infrastructure development and enhance cost efficiency. The transaction also secures a partnership in Blade’s organ transport division, rebranded as Strata Critical Medical, which will remain a separate public company. Joby’s ElevateOS software will be integrated into Blade’s operations to optimize passenger experiences and operational costs.

The strategy of purchasing the top 500 stocks by daily trading volume and holding them for one day delivered a 166.71% return from 2022 to the present, outperforming the benchmark return of 29.18% by 137.53%. This underscores the role of liquidity concentration in short-term stock performance, particularly in volatile markets. High-volume stocks, like Joby, are more likely to experience significant price movements due to institutional and algorithmic trading activity, highlighting the importance of liquidity in driving short-term gains.
