Micron Technology faces a 5% decline to $933, while Western Digital shares have plummeted 7% in premarket trading. The downturn extends to SanDisk and Seagate Technology, both tracking losses of approximately 6%. This volatility reflects growing fatigue among market participants who have spent months aggressively bidding up tech valuations on the promise of AI-driven infrastructure growth.

While Samsung projected continued earnings expansion throughout the remainder of the year, the market response highlights a shift in sentiment. Traders are increasingly wary of the sector's valuation, choosing to lock in gains rather than react to the positive guidance provided by industry leaders. The current selloff underscores the fragility of high-growth tech stocks, as even strong quarterly performance now struggles to satisfy investor expectations.
