Joby Aviation’s Stock Plunges 1.83% on $350M Volume Slide to 247th Rank as Investor Caution Weighs on Electric Air Taxi Developer

On August 21, 2025, Joby Aviation (JOBY) closed at a 1.83% decline, with a trading volume of $350 million, marking a 31.87% drop compared to the previous day’s volume. The stock ranked 247th in terms of trading activity among listed companies on the day.

Recent developments suggest muted investor interest in the electric air taxi developer, as reduced liquidity and lower participation levels indicate cautious positioning. The decline in volume could reflect strategic exits by short-term holders or a broader market reassessment of growth-stage aerospace stocks. With no material news catalysts reported, the move appears to align with normal volatility patterns observed in speculative tech equity segments.

Historical performance analysis of high-volume trading strategies reveals a mixed outlook for volume-driven approaches. A backtest of purchasing the top 500 stocks by daily trading volume and holding for one day from 2022 to present showed a compound annual growth rate of 6.98%. However, the strategy experienced a maximum drawdown of 15.59% during the period, with a notable correction occurring in mid-2023. This highlights the inherent risks of liquidity-dependent strategies in volatile markets.
