Micron stock jumps on $7.8 million insider buy as big banks lift AI-memory targets

Micron Technology shares rose more than 6% in premarket trading on Friday after a company director disclosed buying about $7.8 million of stock this week.

The run-up underscores how quickly money has been flowing back into memory stocks, long seen as cyclical bets, on expectations that artificial-intelligence servers will keep soaking up chips. Micron and SanDisk, along with Western Digital and Seagate Technology, were among the gainers, as investors bet higher prices for DRAM — short for dynamic random access memory — and NAND flash storage will stick.
