• Intraday high of $330.73 and low of $309.91 highlight a volatile 9.2% range
• Options volume spikes on 2025-09-19 expirations, with $340 call contracts leading turnover

Bullish Technicals and Options Flow Drive Sharp Rebound
Fabrinet’s 5.78% intraday surge is driven by a confluence of technical triggers and options activity. The stock pierced above its 30-day moving average of $315.33 and approached the upper Bollinger Band at $360.59, signaling short-term bullish momentum. The K-line pattern summary confirms a short-term bullish trend, while the RSI at 45.22 suggests oversold conditions are easing. Options data reveals aggressive call buying, particularly in the $340 strike, with 301,614 shares traded. This suggests institutional positioning for a near-term rally, likely tied to earnings expectations or sector rotation.

Breakout or Blip? Key Levels and Options to Watch in the Next 48 Hours
Fabrinet’s 5.78% intraday surge is a high-stakes test of its 52-week high and $340 psychological level. While technicals suggest a bullish bias, the MACD divergence and 200-day average lag indicate caution. Traders should monitor the $330 support level and options activity in the 2025-09-19 chain for clues. With Cisco (CSCO) up 1.7% in the sector, sector rotation could amplify FN’s momentum. Act now: Buy the $340 call if the $330.73 high is retested; exit if the $309.91 low breaks. The next 48 hours will define whether this is a breakout or a volatile correction.
