AI Bubble Concerns and Market Reaction Analysis (Nov 22, 2025)

This analysis is based on the Seeking Alpha article [8] that raised AI bubble concerns due to concentrated gains in NVDA, MSFT, and GOOG, and lack of broader AI productivity benefits. Contrary to these concerns, the three stocks posted positive returns in the trading days following the event (Nov 24-26): GOOG +6.88% [2], MSFT +2.83% [1], NVDA +0.77% [0]. The NASDAQ Composite outperformed other indices with a +4.23% gain [7], indicating tech sector resilience. Company-specific news (NVDA rebutting critics [4], MSFT launching Fara-7B [5], GOOG announcing new OS [6]) likely offset bubble fears.
