AAOI Plummets 11.9% Amid Sector Turbulence: What's Fueling the Selloff?

Summary
• Applied Optoelectronics (AAOI) trades at $34.88, down 11.9% from its $41.03 open
• Intraday range spans $34.81–$41.35, with 551,230 shares traded
• Sector leader Cisco (CSCO) declines 0.43% as Communication Equipment faces headwinds

Applied Optoelectronics has plunged to session lows amid a broader Communication Equipment sector selloff, with technical indicators and options activity pointing to heightened volatility. The stock’s sharp decline—its worst intraday performance since late 2024—coincides with a surge in put options trading and a bearish divergence in key technical metrics.

Bearish Breakdown Amid Technical Divergence
The selloff in AAOI reflects a confluence of technical exhaustion and sector-wide weakness. The stock has pierced below its 200-day moving average ($23.83) and the 30-day Bollinger Band midpoint ($33.31), triggering algorithmic selling. With RSI at 54.83 and MACD (2.78) above its signal line (2.38), the price action suggests a breakdown in short-term momentum. The absence of company-specific news means the decline is likely driven by broader Communication Equipment sector rotation, as investors reprice risk ahead of earnings season.

Communication Equipment Sector Weakness: CSCO Drags, AAOI Amplifies
The Communication Equipment sector is under pressure, with Cisco Systems (CSCO) down 0.43% despite its dominant market position. AAOI’s 11.9% drop far outpaces CSCO’s decline, indicating sector-specific vulnerabilities. While CSCO’s modest pullback reflects macroeconomic concerns, AAOI’s collapse suggests overleveraged positions or short-covering in speculative longs. The sector’s exposure to AI infrastructure spending uncertainty—highlighted by IBM’s $11B Confluent acquisition—adds to near-term jitters.
