美股的极致轮动和 Meme 别无二致在上一篇文章里我提到了一个核心体感：今年的美股，越来越像币圈的加速版最直观的表象就是，从 2026 年初开始， $NVDA 这样的大盘股再也无法像过去那样闭眼无脑拉升了。在我看来整个市场彻底变成了一个由 “板块轮动” 主导的绞肉机。如果以为现在还是那个 “买入并持有就能躺赢” 的单边上涨市场，那大概率会被教育得很惨大资金现在的玩法就是打一枪换一个地方，吃完叙事红利立马撤退。拿我之前玩过的 稀土题材和 CPU 题材来说稀土的 $MP / $USAR / $CRML 主要炒作期在关税时期，基于地缘博弈和供应链重塑的宏观预期，一月爆拉二浪打完回原地了CPU 板块 $INTC / $AMD 千亿市值的巨头同样逃不掉轮动的宿命，不要以为只有小盘股才这么玩。今年 1 月 CES 大展前后，Intel 靠发布新一代 Panther Lake 芯片困境反转 + 国家队的概念炒到 54，最肥美的一段过去又回原地； $AMD YTD 表现微跌或许目前的宏观流动性，根本不支持全市场的持续普涨。车身重了，拉不动，朴素的道理。资金只能打游击，集中火力在一个小板块里制造赚钱效应。稀土、CPU，现在又是 ...

Summary of Conference Call Notes Industry Overview - The discussion centers around the impact of AI on various industries, particularly in the electronics sector, highlighting how traditional capacities are being squeezed by AI demands [1][2][3]. Key Points and Arguments 1. **Resource Competition Due to AI** - AI is causing a direct squeeze on traditional capacities across several industries, leading to resource competition [1]. 2. **Storage Industry** - High Bandwidth Memory (HBM) is occupying DRAM capacity, with HBM consuming wafer capacity at a multiple of standard DRAM [1]. 3. **Electronic Fabric** - Low-dielectric constant (low-dk) and low Coefficient of Thermal Expansion (low-cte) materials are taking over the production capacity of 7628, thin, and ultra-thin electronic fabrics due to challenges in crucible methods and long ordering cycles for weaving machines [1]. 4. **Fiber Optics** - AI data centers are consuming fiber optic cable capacity, particularly G.652D loose fiber, due to a shortage of optical preform rods [1]. 5. **CTE Electronic Fabric and Substrates** - ABF substrates are taking over BT substrates, influenced by shared production lines and strict supply chain requirements from companies like Apple [2]. 6. **Copper Clad Laminate (CCL)** - M7, M8, and M9 products are occupying mid to low-end copper clad laminate capacity, with switching costs affecting production efficiency [2]. 7. **CPU Production** - AI servers are taking up consumer-grade CPU capacity, while HBM is squeezing logic chip capacity due to insufficient wafer manufacturing and advanced packaging capacity [2]. 8. **Copper Foil** - High Voltage Low Profile (HVLP) copper foil is taking over standard foil capacity, as production resources are prioritized for high-end products [2]. 9. **Testing and Packaging** - Advanced packaging technologies like CoWoS are occupying traditional testing and packaging capacities, with long expansion times and high costs for packaging facilities [2]. 10. **Electricity Demand** - AI data centers are increasing the load on industrial and residential electricity, leading to power shortages [3]. 11. **Passive Components** - AI servers are consuming high-capacitance, low-loss capacitor materials, impacting the availability of conventional components [3]. 12. **Power Supply** - Titanium-grade AI server power supplies are taking over general server and PC power supply capacity, constrained by high-power components and aging test setups [3]. 13. **PCB Production** - Ultra-high layer boards (UBB/OAM) are occupying the capacity of standard, automotive, and industrial control boards due to bottlenecks in pressing processes [3]. 14. **Automated Test Equipment (ATE)** - High-performance GPUs and HBM testing are taking over testing machines for high-end mobile SoCs and analog chips, with overlaps in equipment and skilled labor [3]. Additional Insights - The result of AI's capacity squeeze is a rapid increase in traditional prices, described as "urgent and fast" [3]. - The phenomenon of stockpiling has emerged as a response to the "squeezed capacity," accelerating the interconnected effects across the electronic materials supply chain [3].
