AsianFin -- Micron Technology (MU) stock rose in early trading Wednesday after the memory chipmaker delivered fiscal fourth-quarter results that topped Wall Street estimates, bolstering optimism around the AI-driven semiconductor rally.

Shares climbed as much as 2% in premarket action to $171.50, briefly surpassing last week’s record intraday high, as investors cheered the upbeat report released late Tuesday. The earnings beat was seen as a positive signal for the broader AI trade and added momentum to Micron’s recent rally.
