# Memory Chips Night Session Mixed Trading

Memory chip stocks displayed mixed performance during Thursday (July 9) night session, with most mainstream names edging lower while a few bucked the trend. As of press time, Micron Technology (MU.US) fell 0.53% to $943.80 in night trading, SanDisk (SNDK.US) declined 2.06% to $1,691.56, Western Digital (WDC.US) slipped 0.24% to $549.00, Seagate Technology (STX.US) dropped 0.51% to $855.60, while Everspin Technologies (MRAM.US) rose 0.63% to $17.50 against the trend.

Trading activity in the memory chip sector moderated during night session compared to regular hours, though select names maintained respectable volume. SanDisk led declines among mainstream names, touching a low of $1,654.36 in night trading, down over $115 from the session high of $1,769.88, with night session turnover reaching $404 million. Micron Technology traded in a range between $930.45 and $981.73, with volume of 660,400 shares and turnover of $631 million, indicating continued market attention on the sector leader. Seagate Technology and Western Digital both exhibited modest pullback patterns, with night session turnover at $16.19 million and $33.46 million respectively, reflecting relatively subdued trading interest.

On the derivative front, memory chip-related ETFs and leveraged products showed divergent performance, reflecting split market sentiment. SNXX.US fell 4.35% to $22.00 in night trading, SNDQ.US gained 5.41% to $3.12, MUU.US declined 1.85% to $690.03, and MUD.US rose 0.68% to $11.78. Overall, the memory chip sector lacked clear directional guidance during night session, with investors awaiting follow-up industry inventory data, demand outlook, and earnings guidance from major companies. With AI server demand continuing to heat up, the inflection point of the memory chip industry cycle remains closely watched by the market, and night session volatility may set the stage for the next regular trading session's direction.
