US Stock Market Movement | Storage Sector Continues Downtrend, Western Digital (WDC.US) Falls Over 6%

```htmlGolden Ten Data APP reports that on Tuesday, the storage sector continued to decline, with Western Digital (WDC.US) and Seagate Technology (STX.US) dropping over 6%, while Micron Technology (MU.US), SanDisk (SNDK.US), and SK Hynix (SKHY.US) fell more than 5%. According to news, over the weekend, Dr. Kan Yu Cao, President of ChangXin Memory, announced at an industry event that the company has made key progress in the next-generation 4F² memory cell architecture and plans to launch DDR5 server memory products based on this architecture by the end of 2026. This announcement has intensified market concerns about Chinese manufacturers accelerating their penetration into the high-end storage chip market. The logic behind the sell-off is clear: if Chinese manufacturers can enter the high-end storage chip market previously dominated by US and South Korean enterprises at lower costs and larger scale, the profit margins of these companies will face significant compression.```
