Joby Aviation Plunges 5% Amid Sector Turbulence: What’s Fueling the Selloff?

Summary
• JOBY’s intraday price drops 4.98% to $13.445, trading below its 52-week low of $4.78
• Turnover surges to 28.5 million shares, with 6.4% of float exchanged
• Sector news highlights moon helium mining and military drone sales, yet JOBY’s decline defies aerospace sector’s mixed momentum

Joby Aviation’s sharp intraday selloff has drawn attention as the eVTOL pioneer trades near critical support levels. With the stock down nearly 5% and volume spiking, the move contrasts with a sector grappling with geopolitical tensions and technological bets. Investors are now dissecting technical signals and options activity to gauge whether this correction marks a buying opportunity or a deeper bearish shift.

Sector Divergence and Technical Weakness
JOBY’s decline is driven by a combination of sector-wide uncertainty and internal technical deterioration. While aerospace peers like Boeing (BA) edged higher on defense contract optimism, JOBY’s bearish K-line pattern and RSI of 28.08 signal oversold conditions. The stock’s breakdown below the 200-day moving average ($9.14) and Bollinger Bands’ lower bound ($12.47) has triggered algorithmic selling. Meanwhile, sector news about moon helium mining and military drone sales has diverted capital from speculative eVTOL plays like JOBY to more established defense firms.

Aerospace Sector Mixed as Boeing Gains
Options Playbook: Capitalizing on Volatility and Gamma
• MACD: -0.337 (bearish divergence), Signal Line: 0.089, Histogram: -0.427 (deepening bearish momentum)
• RSI: 28.08 (oversold), Bollinger Bands: 12.47–20.18 (price near lower bound)
• 200D MA: $9.14 (below current price), 30D MA: $16.59 (key resistance)

JOBY’s technicals suggest a short-term bearish bias, with the 52-week low ($4.78) and 200-day MA ($9.14) as critical levels. The options chain reveals two high-conviction plays: JOBY20250912P13 and JOBY20250919P13.

JOBY20250912P13 (Put, $13 strike, 9/12 expiry):
• IV: 65.76% (moderate volatility), Leverage Ratio: 31.07% (high), Delta: -0.379 (moderate sensitivity), Theta: -0.005 (low time decay), Gamma: 0.249 (high sensitivity to price swings), Turnover: 6,629 (liquid)
• This put option benefits from a 5% downside scenario (targeting $12.78), with a potential payoff of $0.22 per share. Its high gamma ensures amplified gains if JOBY breaks below $13.

JOBY20250919P13 (Put, $13 strike, 9/19 expiry):
• IV: 72.04% (elevated), Leverage Ratio: 20.24% (moderate), Delta: -0.396 (moderate sensitivity), Theta: -0.008 (low decay), Gamma: 0.180 (strong sensitivity), Turnover: 11,999 (high liquidity)
• With a 5% downside target of $12.78, this put offers a $0.22 payoff. Its higher IV and gamma make it ideal for a short-term bearish trade ahead of the 9/19 expiry.

Action: Aggressive bears should prioritize JOBY20250912P13 for a quick move below $13, while JOBY20250919P13 offers a safer, longer-term play if the selloff persists. Both contracts capitalize on JOBY’s technical breakdown and elevated sector volatility.

Critical Levels and Immediate Next Steps for JOBY Traders
JOBY’s 5% intraday drop has created a pivotal juncture for traders. The stock’s breakdown below the 200-day MA and Bollinger Bands’ lower bound signals a potential continuation of the bearish trend. Immediate support at $12.47 and resistance at $16.52 will dictate near-term direction. With Boeing (BA) up 1.37%, the aerospace sector’s mixed momentum underscores the need for precision in positioning. Watch for a breakdown below $12.47 or a rejection at $13.59—either outcome will validate the next phase of JOBY’s trajectory. For now, the options chain and technicals favor a short-term bearish stance, but long-term bulls should monitor a sustained rebound above $16.52 for a potential reversal.
