Semiconductors in focus as Micron, Cerebras shape AI rally

Jun 22, 2026, 2:02 PM EDT1 sourcesAI-analyzed

Why it may matterVerify against the original reporting

Heavy call buying in SMCI, the Micron options with outsized IV and a large single-call bet imply bullish expectations for AI-related demand. Semiconductors historically drive S&P 500 moves due to weight and cyclicality; a beat or strong AI guidance could lift index sentiment in the near term.
