Micron Breaks $1,000 on AI Buzz as 50-Day MA Remains a Mystery

Micron Technology stock closed above $1,000 for the first time since Aug. 17, jumping about 6% to $1,016.59 and helping memories-name peers like SK Hynix and Sandisk gain amid renewed AI infrastructure excitement sparked by OpenAI’s GPT-6 Astra. The stock has tumbled about 20% since June and largely hugged its 50-day moving average near $935 since mid‑August, leaving traders unsure whether that level is now support or resistance. A key catalyst could be Micron’s fiscal Q4 earnings on Sept. 30, with Barron’s noting the stock could double around the $1,100 level; the broader market was weaker on Friday, with the S&P 500, Dow, and Nasdaq all down on payrolls data.
