# Storage Chips Sector Declines in Regular Session, WDC Falls 2.71%, SNDK Drops 2.53%

During the regular session on September 24, the storage chip sector displayed mixed performance with most mainstream stocks under pressure. As of 12:45 ET, Micron Technology (MU.US) traded at **$1,069.64**, down **0.21%**; SanDisk (SNDK.US) at **$1,770.67**, down **2.53%**; Western Digital (WDC.US) at **$460.85**, down **2.71%**; and Seagate Technology (STX.US) at **$918.06**, down **0.55%**. Only Everspin Technologies (MRAM.US) bucked the trend, rising **1.23%** to **$17.30**.

Internal divergence within the sector was evident, with storage device manufacturers facing widespread selling pressure. Western Digital and SanDisk led declines, both falling over 2.5%, reflecting market concerns about storage demand prospects. Micron Technology and Seagate Technology saw more limited losses, staying within 1%. On the derivatives front, SNDQ.US performed strongly, gaining **4.76%** to **$10.35**; while SNXX.US posted the largest decline at **5.14%** to **$17.43**. MUU.US fell 0.42% to $37.03, and MUD.US edged up 0.22% to $9.04.

Overall, the storage chip sector showed a broad decline pattern during today's regular session, with only MRAM.US recording gains among mainstream stocks. Investors should monitor subsequent supply-demand dynamics in the storage market and industry sentiment signals, as sector volatility may continue.
