What happened: Micron (MU) stock rose on Friday, putting the memory chip maker on track for its seventh consecutive intraday record, adding to its weekly gain of more than 30%.
What’s behind the measure: The rally is tied to the AI memory boom, where demand for high-bandwidth memory and other advanced chips has made Micron one of the biggest AI hardware winners on the market. The stock is now up 120% from its March 30 low and nearly 1,000% from its April 8, 2025, post-Liberation Day low.
In numbers: Micron has hit 28 intraday records this year and added $437 billion in market value since March 20, raising its valuation to approximately $800 billion.
Micron is now the fourth-largest chip stock, behind Nvidia (NVDA), TSMC (TSM), and Broadcom (AVGO). It ranks 13th in the S&P 500, behind JPMorgan Chase (JPM) and ahead of AMD (AMD). On the Nasdaq 100 it ranks tenth, just behind Walmart (WMT) and ahead of AMD.
Micron was not alone on Friday. SanDisk (SNDK), Applied Materials (AMAT), ASML (ASML), Intel (INTC), AMD and Nvidia also hit intraday records. The smaller names on that list, including MACOM Technology Solutions (MTSI) and AXT (AXTI), have each achieved more than 30 intraday records this year.
What else do you need to know? The next key area is under the tape. Micron’s former breakout zone, around $465 to $470, is now the support area to watch. However, that is 34% below the current trading level.
