Mag7 Tech Stocks Whipsawed by AI Bubble Fears and Volatile Rate Cut Expectations

Nvidia reported Q3 revenue of $57.01B, adjusted EPS of $1.30, and a Q4 forecast of $65B (beating estimates), initially boosting Mag7 stocks before AI bubble concerns reversed gains [1]. Rate cut probability for December jumped from39.1% (Nov20) to70.9% (Nov21) after New York Fed President John Williams signaled room for further adjustments, helping some Mag7 stocks recover partial losses [2][5]. The tech sector underperformed other sectors on Nov21, rising only0.21% vs Healthcare’s 2.05% gain [0].
