Joby Aviation Plunges 4.49 as $690M Volume Ranks 146th Amid Regulatory Uncertainty and Rate Hikes

On September 24, 2025, Joby Aviation (JOBY) closed at a 4.49% decline with a trading volume of $690 million, ranking 146th in market activity among listed stocks. The drop followed a mixed session marked by elevated volatility and sector-wide caution ahead of upcoming earnings reports.

Recent developments highlighted regulatory progress as the Federal Aviation Administration (FAA) extended its certification timeline review for Joby’s air taxi by six weeks, citing additional safety protocol evaluations. This update added uncertainty to the company’s 2025 commercial launch timeline, prompting a reassessment by investors weighing operational risks against long-term growth potential.

Analyst commentary emphasized the stock’s sensitivity to macroeconomic signals, particularly interest rate expectations. A pre-market report from the Federal Reserve’s latest policy meeting minutes underscored prolonged high-rate scenarios, which pressured high-growth tech and EV-related equities. Joby’s valuation, already stretched on 2026 revenue projections, faced renewed scrutiny as discount rates for future cash flows rose in trading algorithms.

To run this back-test I need a few extra details: 1. Market universe • Are we talking about all U.S.–listed common stocks, or a different market/universe? 2. Trade mechanics • Enter at today’s close and exit at tomorrow’s close (close-to-close), or use next-day open prices? 3. Weighting method • Equal-weight each of the 500 names, or weight by volume / market-cap, etc.? 4. Cash management / slippage • Assume zero transaction costs and full investment every day, or add realistic friction? Once I have these, I can generate the daily rebalanced portfolio signals and run the back-test from 2022-01-03 through today.
