Memory Stocks Had One Reason to Sell Last Week. Monday Added a Second.
The indices: the Dow outran the Nasdaq for the third session in a row
All three indices split again on Monday: the $Dow Jones(.DJI)$ rose 0.38 per cent to 51,850.55; the $S&P 500(.SPX)$ fell 0.06 per cent to 7,807.24, essentially flat; and the $NASDAQ(.IXIC)$ fell 0.44 per cent to 27,245.90. The 10-year Treasury yield stayed at 5.24 per cent, unchanged from Friday.
Monday was the third consecutive session in which the Dow outperformed the Nasdaq. Nvidia fell 1.29 per cent to US$226.32 and AMD fell 2.28 per cent to US$594.24, extending the declines that began last Thursday on the OpenAI revenue report. Memory stocks fell further than the chip names, with a new piece of reasoning added on Monday: reports pointing to competition from Chinese memory maker CXMT. Two paths follow. Should the large cloud companies' third-quarter results leave their capital spending guidance unchanged, the selling since last Thursday is a repricing of a single narrative. Should purchasing plans actually be cut, the weakness of recent sessions is pricing in a larger downward revision ahead. The thing to watch is the capital spending guidance from technology's largest companies when they report.
Memory stocks: CXMT competition reports added supply-side pressure on top of AI funding concerns
$Micron Technology(MU)$ fell 3.88 per cent to US$989.04, $SanDisk Corp.(SNDK)$ fell 5.97 per cent to US$1,487.33 and $SK hynix(SKHY)$ fell 4.02 per cent to US$162.23. Last Thursday's selling came from the demand side — AI funding concerns. Monday added the supply side: reports that Chinese memory maker CXMT has developed competitive DRAM products, prompting a reassessment of whether these companies can sustain the pricing power that drove them higher over the past two years.
The two stories together explain why memory fell harder than compute chips on Monday. The question is how much of CXMT's capacity is actually at scale. Two paths follow. Should CXMT's yields and production volume still be well short of moving the market on pricing, the concern outpaced the reality. Should production ramp quickly, the pricing-power assumption in these valuations has to be rebuilt. The thing to watch is whether CXMT production volumes start appearing in analyst models.
Lumentum: AI capital spending concerns spread to optical networking, and the stock fell nearly 10 per cent
$Lumentum(LITE)$ fell 9.78 per cent to US$995.41, touching a session low of US$980.00, with optical networking names AAOI and COHR also down on the day — a sector-level move rather than a Lumentum-specific one. The stock had set a 52-week high of US$1,143.00 just days earlier; Monday's close put it about 13 per cent below that peak. There were no new company-level negative developments; earnings are scheduled for 5 November.
Optical networking benefits from AI data-centre build-outs through rack-scale interconnect demand, but the other side of that logic is that the benefit requires the build-out to continue. Uncertainty around AI capital spending reaches this chain quickly, and when a valuation already prices in substantial growth, a pullback can be sharp. Two paths follow. Should large cloud companies' data-centre capital spending guidance hold in their third-quarter results, the optical networking move is a temporary overshoot. Should guidance be cut, this will not be the last pullback. The thing to watch is data-centre capex guidance from cloud companies when they report.
Meta: Muse Wonder launched and the stock rose close to 4 per cent against the broader tech weakness
$Meta Platforms, Inc.(META)$ rose 3.38 per cent to US$742.96, reversing direction from the rest of the technology complex. The trigger was the launch of Muse Wonder, an AI-powered content creation platform — a step that deploys AI capability into an existing product surface with an existing user base, rather than one that depends on the continued expansion of compute infrastructure to be viable.
From last Thursday through Monday, compute infrastructure names — chips, memory, optical networking — have consistently underperformed the broader market while AI application names have moved higher. Whether that holds depends on whether the application layer can show actual monetisation in upcoming results. Two paths follow. Should Meta's next earnings report show meaningful revenue and engagement from its AI product lines, Monday's move is a directional signal. Should monetisation still be ahead of the evidence, the application-layer rally is pricing the same kind of expectation that the infrastructure sell-off is questioning. The thing to watch is the revenue and engagement figures for Meta's AI products in the next results.
IREN: the Anthropic report drove the open 3 per cent higher, but the stock closed below Friday
$IREN Ltd(IREN)$ opened Monday at US$36.31, about 3.2 per cent above Friday's close, and hit a session high of US$36.69, but closed at US$34.80, down 1.11 per cent from Friday. The catalyst was a report that IREN had joined Anthropic's network of cloud infrastructure providers. As of the close on Monday, neither company had issued an official statement.
The open-high, close-below-Friday structure makes the market's position clear: there is a premium available for unconfirmed reports of this kind, but holding that premium for an entire session requires official confirmation rather than a news story. Two paths follow. Should a formal arrangement between IREN and Anthropic be announced, Monday's intraday high becomes a data point for where the market priced a confirmed deal. Should no announcement come, this open-high-close-lower pattern is likely to repeat on the next piece of news. The thing to watch is whether IREN or Anthropic issues a formal statement.

如果AI需求持续增长,存储芯片仍有机会;但如果中国厂商扩大产能,导致供应增加、价格下跌,即使销量增长,企业利润也可能受到挤压。
我会重点观察美光(MU)的毛利率、DRAM价格走势,以及大型云公司的AI资本支出指引。
我的策略是暂时不急着抄底,等供需和盈利趋势更明确后再考虑分批买入。股价跌得多,不代表估值一定便宜。
原因在于,AI需求放缓可能是周期性冲击,而供给格局改变可能带来更持久的利润率压力。
首先,AI资本开支决定需求增长速度。微软、谷歌、Meta和亚马逊等云厂商如果削减数据中心投资,HBM、DRAM及企业级SSD的需求预期都会受到影响。但只要AI推理需求持续增长、服务器内存容量不断提升,存储需求仍有结构性支撑。
相比之下,我更关注CXMT带来的长期竞争。
存储行业最大的特点是周期性极强。一旦新增产能集中释放,即使需求仍然增长,也可能因为供给增速更快而出现价格下跌。对于MU这样的企业,真正危险的不是销量减少,而是**出货量增长却无法维持ASP(平均销售价格)和毛利率。**
不过,也不能简单认为CXMT扩产就会立即冲击所有存储产品。
① **产品结构不同:** CXMT主要影响DRAM竞争格局,而SNDK主要面向NAND闪存市场,两者不能直接等同。
② **技术壁垒不同:** 普通DRAM与AI服务器使用的HBM在技术、良率、认证和客户关系上存在明显差异。CXMT即使扩大常规DRAM产能,也不意味着能够立即挑战高端HBM市场。
③ **客户认证需要时间:** 新产能能否影响全球价格,不只取决于生产规模,还取决于良率、成本及客户是否愿意大规模采购。
**我的判断是:未来几个季度,需求端决定股价波动方向,供给端决定长期估值中枢。**
如果云厂商维持资本开支,同时存储厂商ASP和毛利率继续改善,那么近期下跌可能更多是市场情绪调整。
但如果出现资本开支下修、DRAM报价下降、库存上升三个信号同时发生,就需要警惕存储行业进入新一轮下行周期。
对于MU,我会重点跟踪HBM订单、DRAM价格、库存和毛利率指引;对于SNDK,则更关注NAND供需和企业级SSD业务,而不是直接套用CXMT的竞争逻辑。
**最后一个值得思考的问题:AI算力需求持续增长,不代表存储厂商一定能持续提高利润。**
技术进步可以创造需求,但资本密集型行业最终赚多少钱,往往取决于供给纪律和定价权。
因此,相比追逐短期反弹,我更愿意等待下一轮财报验证存储价格和毛利率是否真正出现拐点。
