Changes in US stocks | The storage sector generally fell, SK Hynix (SKHY.US) fell more than 5%

The Zhitong Finance App learned that on Friday, the storage sector generally fell, with SK Hynix (SKHY.US) falling more than 5%, SanDisk (SNDK.US), Western Digital (WDC.US), and Seagate (STX.US) falling more than 4%, and Micron Technology (MU.US) falling more than 3%. The central narrative of the market this week is a marked cooling of AI-related transactions. As market concerns about the cost of AI infrastructure construction continue to heat up, capital flows out of the technology sector, and chip stocks are particularly vulnerable.

Regarding the artificial intelligence sector, Florian Ielpo, macro director at Lombard Odier Investment Managers, pointed out that the key question is whether AI investment can generate attractive returns at the current level of financing costs. This doubt is the core logic that put pressure on tech stock valuations this week.
