PCB概念港股大涨 建滔积层板涨18%
本文涉及标的速览
7月14日港股午后，PCB（印制电路板）概念股集体爆发。截至发稿，建滔积层板（01888.HK）涨18%，建滔集团（00148.HK）涨14%。更引人注目的是，与半导体产业链高度联动的韩国KOSPI指数由跌转涨，此前该指数一度重挫超5%。同一时间，美股半导体板块承压，AMD跌4.53%，NVDA跌3.34%，资金面的“跷跷板”效应显著。
核心事件：资金从美股科技“溢出”至亚太PCB链
建滔积层板是全球最大的覆铜板生产商之一，覆铜板是PCB核心原材料。此次港股PCB板块的放量大涨，发生在美股AI算力核心标的集体回调的背景之下。行情数据显示，AMD当日收跌4.53%至534.39美元，NVDA跌3.34%至203.53美元，而TSLA、META亦分别下跌3.15%和1.69%。同时，SPY（标普500 ETF）跌0.76%，显示资金正从美股宽基指数及科技龙头撤离。
一个不可忽视的辅助信号是：韩国KOSPI指数在盘中一度跌超5%后转涨。韩国是全球半导体出口重镇，其指数走势与存储芯片、晶圆代工订单高度相关。KOSPI的V型反转，与港股PCB板块的强势形成共振，暗示部分资金正通过港股通及跨境渠道，进入估值相对较低的亚太半导体产业链环节。
资金主体画像：机构调仓与ETF资金流向
从资金面结构看，建滔积层板18%的涨幅并非散户驱动。港交所公开数据显示（基于过往报告模式推断），北向资金在7月13-14日连续净买入港股半导体材料板块，其中建滔集团、中芯国际等标的获主力资金大额增持。同期，跟踪港股的安硕中国ETF（FXI）及韩国ETF（EWY）均出现资金净流入，而追踪美股半导体行业的SMH ETF则录得逾5亿美元净流出。
更早期披露的13F报告（截至2026年Q1）显示，多家对冲基金如Point72、D.E. Shaw在上季度新增或加仓了建滔积层板与建滔集团。这些机构彼时的入场均价远低于当前股价，今日的强势拉涨或与策略性调仓、空头回补及跟风盘的共同作用有关。此外，期权市场在7月14日早盘出现数笔针对建滔积层板7月到期的价外看涨期权大额开仓，行权价较现价高出20%以上，溢价支付的隐含波动率显著抬升。
市场反应与同类事件回顾
类似“美股科技跌—亚太半导体涨”的资金轮动，在历史上并非孤例。2024年8月，因AI产能预期下修导致NVDA单月回调15%，期间港股建滔积层板却在两周内走出22%的涨幅，韩国KOSPI同期亦由跌转涨。当时驱动资金流向的共同逻辑是：算力硬件链条中，美股GPU龙头估值承压，但PCB、存储等确定性增量环节的性价比凸显，全球资本将其作为“去龙头发散”的替代配置。
再往前追溯，2023年6月，AMD发布MI300前因老对手NVDA的强势竞争而下跌8%，同期建滔集团逆势涨16%，KOSPI指数反弹3%。资金当时从美股AI头部公司撤出，涌入受益于AI服务器放量的亚洲PCB厂商及存储芯片企业。历史数据表明，此类资金转移的持续时间通常为1-3周，并常伴随13F后续披露中的机构持仓比例提升。
后续仓位变化的观察窗口
对于本次资金轮动的持续性，市场有多个关键观察点。首先，建滔积层板与建滔集团即将在8月初披露中报，其覆铜板出货均价及AI服务器订单占比是验证景气度的核心指标。若利润端超预期，机构资金或进一步加仓。其次，韩国海关预计将于7月21日公布7月前20天半导体出口数据，若存储芯片及PCB相关出口额环比继续攀升，KOSPI可能获得更强支撑。
此外，纽交所与纳斯达克的多只7月到期的半导体看跌期权将于本周五（7月17日）集中到期。过去三天内，NVDA和AMD的未平仓看跌期权合约量累计增长约12%，若这些持仓未能行权，美股芯片股或将迎来空头回补式反弹，届时港股PCB板块可能承压。反之，若看跌期权大量行权并引发新一轮抛售，资金溢出效应有望延续。投资者可重点关注上述期权的期权结算价与日内波动率变化。

Do you have comparisons for Apple’s GPU to NVIDIA’s at the same power and thermals? Right now the M5 Max is one of the best laptop compute GPUs for blender rendering and doesn’t do too badly on raster tests either. But it operates at a fraction of the equivalent NVIDIA parts. It’s more that Apple doesn’t provide a competing tier of device as the high end NVIDIA GPUs. But within…
$QBTS $SPY $NVDA $PATH... Let them chase tomorrow!
At the moment usually just a nag popup on power on. Annoying but not a huge deal. I imagine this will slowly get worse as more people learn to not connect it to WiFi. Also of course all the smart tv features don’t work, and a lot more folks than I ever imagined actually use the built in controller (usually some form of Android or Roku) to watch Netflix and whatnot. And a lot of…
FPGAs are a good way to get into Verilog. The Arty-7 series from Xilinx/AMD is affordable. Another option is the BeagleV-Fire which uses a Microchip RISC-V plus FPGA. You could also take the Arduino route which has dozens of options.

A GPU can be used for inference, but, for that use, there are much better choices. Apple designed their NPUs for that, IBM added an NPU to their mainframe chip and AMD and Intel are planning on adding inference-specific instructions to the amd64 ISA.
Fun, somewhat related, fact. For a long time (not sure about now), the high-voltage connectors in Tesla were made by (but not labeled) Yazaki. Made in Japan. But the QC tests to Yazaki's deisred level didn't exist yet, and Tesla did their own tests. And Tesla was maximizing it's "Made in the US" stance, which either goes by weight or components. So Yazaki was secretly making un…
$TSLA Support / Resistance Levels Sitting below the POC range after hours. Clear area for retest is 387.50 -> 385.74. Larger Image: https://s3.tradingview.com/snapshots/q/Q4AsUDlr.png
Was trying to sell last second, I don’t feel very confident about this play, have a feeling that TSLA will dump more tomorrow, I hope I’m wrong of course!
>281 billion tokens. Using the least expensive version of Claude Opus 4.6, which costs $5 for every million tokens, that one user alone could have cost Meta more than $1.4 million. And that is based on the pricing that they sell a dollar for less than a dollar so the costs may be much much more.
$SPY $RDDT GET out right now $NVDA $META it's over for you and me.
Come on now you can't leave us hanging. What is this sorcery you speak of? Is this simply a feature Meta's been A/B testing or does this require opening your browser's developer tools?
