Amprius Technologies Plunges 2.8% Amid Volatile Intraday Action: What's Fueling the Selloff?

Summary
• Amprius Technologies (AMPX) drops 2.83% to $13.06, hitting a low of $12.72
• Intraday range of $1.35 amid $8.4M turnover
• 52-week high of $14.07 now 7.7% below current price
• Options chain shows 119% implied volatility on key contracts

Amprius Technologies faces a sharp intraday selloff as mixed news flows and technical indicators clash. The stock’s 2.83% decline to $13.06 reflects heightened volatility, with a $1.35 intraday range and elevated options activity. Investors are parsing recent strategic partnerships and production updates against broader sector weakness, as Tesla’s -4.14% drag on the Electrical Equipment sector amplifies uncertainty.

Product Launches and Strategic Moves Spark Market Uncertainty
AMPX’s selloff follows a flurry of recent developments, including a $35M purchase order from a leading UAS manufacturer and a partnership with Nordic Wing to enhance drone endurance. While these contracts signal growth potential, investors are wary of execution risks. The stock’s 52-week high of $14.07 now acts as a psychological barrier, with the 200-day moving average at $4.63 far below current levels. Options data reveals 119% implied volatility on the AMPX20251017C13 call, suggesting traders anticipate sharp price swings. Mixed sector sentiment, including Tesla’s decline, further clouds the outlook.

Electrical Equipment Sector Under Pressure as Tesla Slides 4.1%
The Electrical Equipment sector faces headwinds as Tesla (TSLA) drops 4.14%, reflecting broader market jitters over EV demand and regulatory scrutiny. AMPX’s 2.83% decline aligns with sector trends but is amplified by its speculative profile. While Tesla’s scale offers some resilience, AMPX’s reliance on niche markets like drones and military contracts makes it more vulnerable to sentiment shifts. The sector’s 34.8x price-to-sales ratio remains elevated, raising questions about sustainability.

Options and ETF Strategies for Navigating AMPX's Volatility
• MACD: 1.24 (bullish), Signal Line: 1.06, Histogram: 0.18 (momentum)

• 200-day MA: $4.63 (far below price), 30-day MA: $9.49

AMPX’s technicals suggest a short-term bullish trend but overbought conditions. Key support at $10.57 (middle Bollinger Band) and resistance at $14.07 (52-week high) define the near-term range. The stock’s 7.97% turnover rate and 119% implied volatility on options highlight liquidity and volatility risks. Two top options:

Act Now: AMPX's Volatility Presents High-Risk, High-Reward Opportunities
AMPX’s sharp selloff reflects a mix of strategic optimism and sector-wide jitters. While the stock’s 2.83% decline tests key support levels, its 119% implied volatility and overbought RSI suggest a potential rebound. Investors should monitor Tesla’s -4.14% drag on the sector and AMPX’s $12.72 intraday low as critical thresholds. For those with a high-risk appetite, the AMPX20251017C13 call offers a volatile but liquid bet on a short-term bounce. However, prudence is advised given the stock’s -51.89x dynamic P/E and reliance on niche markets. Watch for a $13.50 breakout or breakdown below $12.50 to dictate next steps.
