A volatile day for Aehr Test Systems has unfolded under the weight of sharp intraday selling pressure. With the stock dropping nearly 9.1% and trading well below its 30-day moving average of $35.32, investors are scrambling for answers. The semiconductor sector itself remains mixed, with ASML falling 4.4%. This article delves into the technical and fundamental catalysts behind the drop and highlights actionable options for traders to consider.

Supply Chain Woes and Regulatory Scrutiny Fuel Sell-Off
The sharp decline in AEHR stems from growing concerns over global semiconductor supply chains. Reports of helium shortages and tungsten supply constraints are raising alarms in the sector. Tungsten, a key material used in semiconductor manufacturing, has surged in price due to Chinese export restrictions and military demands. These bottlenecks could delay production and testing, directly impacting Aehr’s business model. Compounding this, recent regulatory actions—such as the U.S. Justice Department’s charges against three individuals for diverting servers with Nvidia GPUs to China—have heightened sector-wide uncertainty. Aehr, a provider of automated test equipment for semiconductors, is not immune to these risks. The selloff reflects fears of declining demand and regulatory headwinds.

Semiconductor Sector Reels Amid Global Headwinds
The broader semiconductor sector is under pressure as global supply constraints and regulatory scrutiny converge. ASML, the sector’s bellwether, has fallen 4.4%, signaling a broader pullback. The industry is facing a perfect storm: geopolitical tensions, supply chain bottlenecks, and rising costs for critical materials. While some companies like AMD and Teradyne remain in the spotlight due to strong earnings and market share gains, the current environment poses a near-term risk for smaller players like Aehr. The sector’s resilience will depend on whether these headwinds are short-lived or mark the start of a more protracted downturn.

Options and Technical Setup for Volatile Semiconductor Market
• 200D MA: 24.11 (below current price)
• 30D MA: 35.32 (resistance ahead)
• Bollinger Bands: Price at 34.31 near lower band (32.87) suggesting oversold
• RSI: 50.47 (neutral but nearing support)
• MACD: 1.66, Signal: 2.47, Histogram: -0.81 (bearish divergence)
• Kline pattern: Short-term bearish trend with bullish engulfing pattern suggesting potential reversal

The stock is currently trading near the lower Bollinger Band, indicating oversold conditions. The 30-day MA at $35.32 and 200-day MA at $24.11 are both positioned to serve as psychological support and resistance. A breakdown below $33.94 could trigger further bearish momentum, while a rebound above $37.80 may indicate short-term stabilization. Given the bearish bias, short-term options strategies are worth considering.

Two standout options from the chain are:
• AEHR20260417P35: Put option with $35 strike, expiring April 17, 2026. IV: 113.27% (elevated), Delta: -0.4665 (moderate), Theta: -0.0442 (time decay), Gamma: 0.0366 (price sensitivity), Turnover: 74,609 (liquid).
• AEHR20260417C30: Call option with $30 strike, expiring April 17, 2026. IV: 30.00% (moderate), Delta: 0.9429 (deep in the money), Theta: -0.0465 (significant time decay), Gamma: 0.0398 (high sensitivity), Turnover: 174,509 (very liquid).

The AEHR20260417P35 stands out for its balanced mix of leverage and liquidity. The 113% IV reflects elevated volatility expectations, and the moderate delta of -0.4665 suggests it can react meaningfully to a further decline in the stock. A 5% move down to $32.59 would yield a payoff of $2.41 per contract, offering a high-reward setup for bearish traders. This option is ideal for those betting on a near-term pullback.

The AEHR20260417C30 is a deep in-the-money call with very high turnover and significant gamma and theta. While it won’t profit from a decline, it offers a low-risk hedge if the stock rebounds above $37.80. Its high liquidity ensures smooth entry and exit, making it a solid short-term holding for directional traders. Aggressive bearish players should consider AEHR20260417P35 into a breakdown below $33.94.

Backtest Aehr Test Systems Stock Performance
After experiencing a -9% intraday plunge from 2022 to the present, AEHR has shown positive short-to-medium-term performance. The 3-Day win rate is 52.74%, the 10-Day win rate is 52.55%, and the 30-Day win rate is 54.20%, indicating a higher probability of positive returns in the immediate aftermath of the plunge. The maximum return during the backtest was 12.89% over 30 days, suggesting that while there is volatility, AEHR can recover and even exceed its pre-plunge levels.

Time to Act: Aehr Faces Key Levels and a Critical Decision Point
Aehr Test Systems is at a critical juncture, with its near-term direction hinging on whether it holds above $33.94 or breaks below this level. The Bollinger Bands and RSI suggest oversold conditions, while the MACD divergence points to potential bearish continuation. Investors should closely monitor the 200-day moving average at $24.11 as a long-term floor and the 30-day MA at $35.32 as a key resistance. Meanwhile, ASML’s -4.4% decline reinforces the sector’s fragile mood. A breakout above $37.80 could signal stabilization, while a breakdown below $33.94 might accelerate the selloff. Those with a bearish outlook should consider the AEHR20260417P35 for short-term volatility exposure. If $33.94 breaks, short-side positioning becomes high priority.
