# 美股实盘：搅 * 棍助力 AI 降温（20260705）

**综述：**

本周标普 500 指数 上涨 1.76%，我的实盘净值 下跌 7.54%。

2026 年内标普 500 指数 上涨 9.32%，2026 年内我的实盘净值 上涨 99.76%（年初净值为 2.20，本周净值 4.39）。

**交易：**

清仓 NVDA，买入等额 BE

卖出一半 GLW，买入等额美债

**持仓：**

SNDK 33.4%，MRVL 7.8%，LITE 8.1%，BE 10.0%，NEM 11.6%，GLW 6.6%，NOK 6.8%，现金/美债 15.6%。

有四舍五入，且一般不记录低于 1% 的迷你仓和短线投机操作。

**复盘：**

先说交易，进行了两笔调仓。nvda 切 be 上周已经暗示过了，就是短期赔率上的考虑，be 因为指数调仓引发的超跌，我认为性价比更高，这只之前本来是我的重仓股，趁着近期的大幅回调就接回来了，当然英伟达后续还是倾向也买回来的，看看再说。减仓 glw 和之前减仓 mrvl 的逻辑一样，属于到估值表卖点附近了，为了防止卖飞无脑砍半锁定利润，留半仓避免出现之前卖飞 be 接不回来的尴尬。

尽管这两笔操作都是赚的，但仍然没能阻止我的账户连续第二周回调，而且是大幅下修，主要原因还是之前涨得猛的这些 AI 基建板块个股，短期都涨得比较猛了，然后美股知名搅屎棍 META，突然放出准备出租算力的新闻，市场遂借坡下驴，直接以最惊悚的鬼故事 AI 讲不下去了资本开支要大砍来引发全球暴跌，可看过新闻原文都知道，实际上是 META 自己模型太拉没人用，别人都缺的东西它花不完，只能被迫把中低端算力弄出去降点成本。

而更无语的是，等美股放假关门了，META 又爆出正在考虑委托三星生产价值 10 亿韩元的定制芯片。好嘛，正反话都让你一家说了，下周先来个高开？

---

**个股方面，**

1、科技：NVDA/GOOG

本周虽然 AI 基建大跌，但大盘指数却都是涨的，跷跷板效应，小妹不能崩老头了就跌，老头能不被蹦了就涨。

长期看这都是小插曲，接下来的长线剧本，肯定还是想办法继续梭哈，因为没人敢停下，一旦被 AI 淘汰可比短期花点钱卷 AI 的损失大，目前来看 M7 里 META 是明显的掉队了，所以扎克很急。

据报道，OpenAI 已将 IPO 推迟到 2027 年。据称，公司目前的财务状况太差，投资者难以接受其高达 1 万亿美元的估值。公司的顾问曾建议下调估值，但 Sam Altman 坚持认为，1 万亿美元是绝对不能让步的底线。推迟是好事，最好明年再推到后年，不然短期内连续上三个巨无霸，其他板块容易被吸干，没那么多钱给这些动不动万亿市值的公司。

2、存储：SNDK/MU

韩国两则重磅消息：

今天三星也计划在 Q3 将 DRAM 价格上调 20% ，再苦一苦电子消费品公司吧，未来可能会更苦，巨头们生产的东西留给碳基的越来越少，碳基有能力消费的也越来越少。  

SK 海力士 ADR 目前暂定于 2026 年 7 月 10 日在美国纳斯达克挂牌并开始交易，也就是下周了。此时下周应该能引发存储板块大幅修复，不过需要预计的是，海外巨头美股上市，往往也是阶段性高点的信号，因为那天冲高第二天回本国股市拉高套利结账的剧本，可是经常上演的。

美股这边特师傅继续喊单美光，除了自己发的空气币外，他在股市里喊的单基本都能让人赚钱，信不信各位随意。

3、光通信：LITE/MRVL/GLW/NOK

近期承压的板块，主要原因其实就是涨多了，再加上此前预期非常高的 CPO 延期，打掉了很大一部分溢价，所以需要继续熬一熬。光通信的王者大都在 A 股，但 CPO 作为长线未来形态，长期看肯定还是差不了的，但中短期没有技术突破的前提下，没故事可讲，而且还是业绩真空期，大家大眼瞪小眼。

4、金属：GLD/NEM

千呼万唤始出来，沃什终于出来发言了，偏鸽，三次加息的鬼故事彻底终结，但是考虑到 6 月降息早没了，9 月降息他也没讲，所以目前只能算中性的今年内可能降息，有色板块可以赢得少量呼吸权了，后市继续小幅看多，起码不能跑输美债，有一定修复空间。

5、电力：BE

虽然被剔除了罗素 2000 的群聊，但本周正式加入罗素 Top200 的新群，这就是成长的代价，股价修复了不少，估值仍然不便宜，但是考虑到美国电力的稀缺性甚至比肩存储，还是选择继续高看一眼吧，但该股波动非常剧烈，和我从去年拿过来的都应该有感受，慎抄。  

6、下周计划

躺为先。
