Why Are Memory Chip Stocks Micron, SanDisk, and SK Hynix Falling in Pre-Market Today, Sept. 10?
Micron (MU), SanDisk (SNDK), and SK Hynix (SKHY) fell in pre-market trading due to profit-taking and Kioxia's comments on memory prices. Kioxia's CEO warned against sharp price increases, citing potential harm to AI investment and market growth. All three stocks had gained on Wednesday, with SK Hynix up 7.05%, Micron up 2.75%, and SanDisk up 1.51%. Broader market pressure from higher Treasury yields and oil prices also contributed to the decline.
