Astera Labs (ALAB) Plunges 4.9% Amid MACD Death Cross and Bearish Options Flow – What’s Next for the Semiconductor Play?

Summary
• Astera Labs (ALAB) trades at $158.92, down 4.9% intraday with a 52-week high of $262.90.
• Bollinger Bands show the stock is near the lower band at $139.65, signaling oversold conditions.
• Options data reveals high implied volatility (up to 98.32%) and leveraged put options surging in volume.
• Institutional investors have increased short interest by 1.75% in the past month.
Today’s sharp decline in ALAB reflects a confluence of technical breakdowns and bearish options activity. The stock’s 15-minute chart triggered a MACD death cross and bearish KDJ divergence, while the options market shows aggressive shorting. With turnover at 5.01 million shares and a 3.73% turnover rate, liquidity remains robust, but the path forward hinges on key support levels and institutional positioning.

MACD Death Cross and Bearish KDJ Signal Short-Term Downtrend
The 15-minute chart of ALAB triggered a critical MACD death cross on January 6 at 09:45, where the 12-period EMA crossed below the 26-period EMA. This technical signal, combined with a bearish KDJ divergence (where the stochastic oscillator’s %K line fell below %D), confirmed a shift in momentum. The stock’s intraday low of $151.10 suggests short-term sellers have taken control, exacerbated by elevated implied volatility in the options market. While the 52-week high of $262.90 remains distant, the 200-day moving average at $135.06 now looms as a critical psychological barrier. Institutional short interest rising by 1.75% further amplifies downward pressure, as large players capitalize on the technical breakdown.

Backtest Astera Stock Performance
The backtest of ALAB's performance after a -5% intraday plunge from 2022 to now shows mixed results. While the 3-day and 10-day win rates are high at 53.52%, the 30-day win rate drops to 50.70%. This suggests that while ALAB has a good chance of recovering short-term losses, longer-term returns are more variable. The maximum return during the backtest was 18.62%, indicating that while there is potential for gains, they are not consistently high.

ALAB at Crossroads: Watch $139.65 Support and Sector Sentiment
Astera Labs’ 4.9% intraday drop reflects a technical breakdown confirmed by the MACD death cross and bearish options flow. While the 200-day MA at $135.06 and lower Bollinger band at $139.65 offer near-term support, institutional short interest and elevated IV suggest volatility will persist. Investors should monitor the $139.65 level as a critical inflection point—break below it, and the stock risks a deeper correction. Conversely, a rebound above $163.13 (middle Bollinger band) could attract buyers, especially with the semiconductor sector showing resilience (e.g., Intel’s 0.76% intraday gain). For now, the options market favors directional bets over hedging, with leveraged puts and calls offering high-reward scenarios. Watch for $139.65 breakdown or a breakout above $163.13 to define the next move.
