Abstract

7月暴跌的警告仍未离去。内存股在上半年曾出现抛物线式上涨,价格已包含极高的盈利预期。

7月30日,美股AI和半导体大涨。其中,闪迪在暴跌后形成高波动的V形修复,但远未收复7月跌幅。

  当地时间7月30日,美股强劲反弹,人工智能(AI)和半导体成为主线。

  道琼斯工业平均指数收于52208.06点,涨613.92点,涨幅1.19%;标普500指数收于7437.63点,涨121.48点,涨幅1.66%;纳斯达克综合指数收于25122.18点,涨679.24点,涨幅2.78%。

  “七巨头”涨势分化明显。微软大涨15.51%,收于451.10美元,强劲财报和云业务增长缓解了市场对AI资本开支的担忧。英伟达涨2.65%,亚马逊涨3.90%,特斯拉涨3.53%;苹果跌1.41%,谷歌母公司字母表跌(Alphabet)0.91%,Meta Platforms(脸书母公司)跌7.95%。

  内存和AI半导体领涨。美光涨18.36%,收于874.66美元;闪迪涨25.99%,收于1279.96美元;西部数据涨15.37%,希捷涨11.41%,博通涨4.73%。安硕半导体交易型基金涨8.50%,费城半导体指数当日涨约8%。

  闪迪在暴跌后形成高波动的V形修复,但远未收复7月跌幅。盘中一度最高达到1365美元,较前收盘最高上涨34.37%,收报1279.96美元,单日上涨264.1美元。

本轮回弹来自整个AI与半导体板块,而非闪迪单独发布了重大利好。微软财报显示Azure增长强劲,市场重新相信大型科技公司的AI投入正在转化为收入和利润,带动存储器、处理器及半导体设备股集体反弹。

  此外,无论是在芯片股还是内存股范围内,闪迪在过往波段中的涨幅和跌幅都是最夸张的,以6月30日收盘价2273.73美元计算,即使7月30日暴涨26%,其股价截至当天仍累计下跌43.71%。换句话说,本次暴涨更多是在修复前期踩踏,而不是重新回到原来的价格中枢。

  闪迪已确定于8月5日公布2026财年第四季度及全年业绩。在业绩窗口临近时,空头止盈、投资者抄底和期权对冲容易互相强化。

  微软最新季度收入及利润均超过市场预期,Azure及其他云服务收入同比增长43%,微软云收入增长27%至593亿美元;公司同时表示,2026年资本支出预期没有改变。对内存产业而言,这组数据的重要性在于:全球最大的AI基础设施买家仍在扩建算力,而新增服务器不只需要GPU,也需要高带宽存储器(HBM)、服务器DRAM和企业级固态硬盘。此前市场担心云厂商削减投资,微软的业绩至少暂时打消了这一疑虑。

  HBM需要更复杂的堆叠和封装,占用更多晶圆产能;生产商将产能优先分配给HBM和服务器DRAM,又进一步挤压传统DRAM与NAND闪存供应。彭博援引产业人士判断,全球基础晶圆供给相对需求仍存在两成以上缺口,紧张状况可能延续数年。这也是美光、SK海力士和三星能够维持定价权的核心原因。

  7月暴跌的警告仍未离去。内存股在上半年曾出现抛物线式上涨,价格已包含极高的盈利预期。近期市场担忧主要集中在三点:其一,微软、Meta、Alphabet和亚马逊的AI投入规模越来越大,但自由现金流和投资回报能否同步增长仍待验证;其二,三星、SK海力士和美光均在加快扩产,2027年以后供给增加可能削弱议价能力;其三,中国内存厂商长鑫存储的扩张和上市,使市场重新评估成熟DRAM领域的竞争格局。此外,高利率和长端美债收益率上升,也被认为会放大高波动科技股的估值压力。

Bank of Korea Reveals Results of Tokenized Deposit Testing

The Bank of Korea has announced the results of its pilot test for tokenized deposits. Involving 28 central banks and international financial organizations, the project saw participation from major South Korean banks including KB Kookmin Bank, NH NongHyup Bank, Shinhan Bank, Woori Bank, and Hana Bank. Transactions, from payment orders to final settlement, were completed in real time, averaging just 80 seconds. The test involved 30 transactions across 17 different scenarios—such as corporate and interbank transfers—and was conducted in six currencies, including the Korean won, US dollar, and euro, with a total transaction value reaching approximately $995,000. The central bank reported that the platform operated stably throughout, despite being only partially connected to the existing banking infrastructure. Settlements using tokenized deposits were executed seamlessly, quickly, and transparently. An internal transfer of 20 million won (about $13,890) between NH NongHyup Bank and Shinhan Bank was also successfully processed via the Project Agora platform, which involved connecting to the Bank of Korea's CBDC test platform, Project Hangang. Additionally, KB Kookmin Bank and Japan's MUFG Bank tested cross-border payments using these deposit tokens—digital certificates issued by commercial banks within the pilot, not directly by the central bank. The Bank of Korea plans to continue testing payments with tokenized deposits. This follows last year's pledge by South Korean authorities to tighten regulations for won-based stablecoins, which will require approval from both the central bank and the Financial Services Commission.
