Benzinga盘后综述五家热门股：存储股因CXMT技术进展已大跌，Cerebras、Meta与SoundHound各据旧消息波动

Major U.S. indexes closed mixed on Monday. The Dow Jones Industrial Average rose 0.38% to 51,850.55, while the S&P 500 edged down 0.06% to 7,807.24 and the tech-heavy Nasdaq fell 0.44% to 27,245.90.
Geopolitical tensions, third-quarter earnings expectations and upcoming inflation data shaped the broader market backdrop as investors monitored developments surrounding Iran and the Strait of Hormuz.
These are the top stocks that gained the attention of retail traders and investors throughout the day.
Micron Technology Inc. (NASDAQ:MU)
Micron Technology stock fell 3.88% to close at $989.04, trading between $978.50 and $1,002.67; its 52-week range is $186.25 to $1,255. In after-hours trading, the stock declined 1.4% to 975.20.
Micron, SK Hynix and SanDisk lost a combined $108 billion in market value on Monday after China’s ChangXin Memory Technologies reported advances in chip design that could intensify competition and ease AI-driven memory supply constraints. Micron and SK Hynix each fell 4.5%, while SanDisk dropped 6.6%, as investors weighed the potential impact of increased supply on memory pricing.
Cerebras Systems Inc. (NASDAQ:CBRS)
Cerebras Systems dropped 10.69% to $146.62, reaching an intraday high of $161.20 and low of $145.75; its 52-week range is $145.75 to $385.
Cerebras shares came under pressure after a SemiAnalysis report suggested OpenAI had switched its fastest GPT-6.1 Sol tier from Cerebras hardware to Nvidia GPUs, though neither company confirmed the change. Shares subsequently rebounded about 9% after OpenAI CEO Sam Altman reaffirmed Cerebras as a “close partner,” while Barclays analyst Tom O’Malley said the relationship remained strong.
SanDisk Corp. (NASDAQ:SNDK)
SanDisk stock declined 5.97% to close at $1,487.33, after moving between $1,464.43 and $1,539.10; its 52-week range is $120.96 to $2,354.39. In after-hours trading, the stock declined 2.24% to $1,454.
SanDisk lost approximately $15 billion in market value amid concerns that advances by China’s ChangXin Memory Technologies could increase chip supply and pressure memory prices, contributing to a broader $108 billion selloff across major memory stocks. Despite the decline, analysts remained optimistic about AI-driven NAND demand and tight supply through 2027, ahead of SanDisk’s Oct. 29 earnings report, when revenue was expected to reach $10.64 billion and EPS $46.22.
Meta Platforms Inc. (NASDAQ:META)
Meta gained 3.38% to finish at $742.96, with an intraday high of $752.24 and low of $727.64; its 52-week range is $520.26 to $779.82.
CNBC’s Jim Cramer described Meta as a "monster long" after Sensor Tower data showed its Muse AI app achieved 73.3% Day-1 user retention, compared with ChatGPT’s 41.3%. However, ChatGPT overtook Muse by Day 9 and maintained higher Day-14 retention of 26.8%, versus Muse’s 22.5%, suggesting Meta’s AI app had strong initial engagement but weaker longer-term retention.
SoundHound AI Inc. (NASDAQ:SOUN)
SoundHound AI lost 7.79% to close at $4.97, trading as high as $5.35 and as low as $4.96; its 52-week range is $4.96 to $22.17.
SoundHound AI shares extended their decline amid a broader technology selloff and concerns over integration risks following its $43 million acquisition of LivePerson. The company reported 45% year-over-year second-quarter revenue growth, reflecting a slowdown from previous quarters, while maintaining annual revenue guidance of $230 million to $260 million, excluding contributions from the acquisition.
