AI-Memory Rally Lifts Momentum as S&P Stays Flat
Market Environment
Stocks finished mixed but constructive. The S&P 500 was basically flat, while Nasdaq, small caps, international equities, semiconductors, industrials, materials, health care, and biotech carried the better tone.
The clearest driver was the Micron-led AI-memory rally. Storage and semiconductor names attracted the strongest bid, while software and crypto-linked exposure lagged.
For traders, the message was constructive but selective: hardware and infrastructure momentum worked, but the tape was not lifting every high-beta pocket.
