Micron shares fell 3.3% in premarket trading on Friday. Intel stock dropped 2.8%, and Advanced Micro Devices shares fell 2.8% for a second day. Nvidia's stock was down 1.4% at the time of writing. Broadcom reported its second-quarter fiscal results on Wednesday evening, projecting $16 billion in AI chip revenue in the third quarter, below estimates of $17.2 billion.

Broadcom kept its fiscal year 2027 outlook unchanged at $100 billion despite beating on revenue and profit in the quarter. AVGO stock tumbled 12.6% on Thursday, marking its steepest single-day decline since January 2025, and fell 2% in Friday's premarket session.

On Stocktwits, retail sentiment for SOXX (the iShares Semiconductor ETF) fell into the 'extremely bearish' zone (8/100). Sentiment for MU was 'neutral', for NVDA and AMD was 'bullish', and for INTC was 'bearish'.
