Resumen

纳斯达克 100 前十大成分股过去一年平均暴涨 784%,闪迪以 3960% 的涨幅超越 2000 年互联网泡沫时期高通的纪录。当「这次不一样」的论调再次响起,历史是否会以同样的韵脚重演?

撰文:BiyaMews

看着纳斯达克 100 指数前 10 大成分股过去一年平均涨了 784%,我脑海里浮现的是 2000 年互联网泡沫破裂前那些疯狂的日子。当时高通一年涨了 2600%,人们说这次不一样。现在,闪迪一年涨了 3960%,比高通当年还猛 1300 个百分点,而人们又说这次不一样。

历史从不会简单重复,但押韵得让人后背发凉。

这轮涨幅到底有多夸张?

先看一组让人窒息的数据。根据 BTIG 首席技术分析师 Jonathan Krinsky 的最新报告,过去一年纳斯达克 100 指数表现最好的前 10 只股票平均涨幅高达 784%。作为对比,1999 年这个数字是 559%,2000 年 3 月市场见顶前一年是 622%。

更扎心的是,1999 年表现最好的高通,52 周涨幅 2600%;2000 年见顶前最好的 Strategy,涨幅 1260%。而现在,闪迪以 3960% 的涨幅碾压了这两个纪录。

我曾在 2020 年 3 月美股熔断时抄底,当时觉得那是十年一遇的机会。但说实话,看到这种涨幅,我更多是恐惧而不是兴奋。因为上次见到这种级别的疯狂,还是在 2000 年 3 月,之后纳斯达克跌了 78%。

作为本轮上涨的核心引擎,费城半导体指数(SOX)的表现同样逼近历史极值。互联网泡沫时期,该指数最佳 52 周滚动回报率为 264%,而现在这个数字是 145%。虽然还没破纪录,但已经是过去 26 年来最接近极值的水平。

市场为什么不讲理地涨?

就在我写这篇文章时,中东局势出现缓和迹象,油价大跌,美债收益率跟着走低。市场对美联储年内加息的预期基本消失,AMD 等芯片巨头交出亮眼财报。这一切让股市环境显得「完美」。

但问题在于,这种「完美」让我想起 2018 年 1 月时的情况。当时所有人都觉得经济好、企业盈利强、减税利好,结果 2 月份市场突然暴跌,标普 500 单周跌了 10%。

彭博宏观策略师 Cameron Crise 说得对,这种宏观与微观层面的完美共振,让持怀疑态度的投资者感到背脊发凉。因为股市往往在好消息中见顶,而不是坏消息。

这次和 2000 年有什么不同?

最大的不同是基本面。2000 年互联网泡沫破裂时,很多公司根本没有盈利,全靠讲故事撑估值。而现在,AI 和半导体公司的业绩是实实在在的。英伟达、AMD 的财报数据摆在那里,营收和利润都在增长。

但这也正是我担心的。因为当所有人都用「基本面好」来论证市场不会跌的时候,往往就是调整的前兆。我记得 2021 年牛市时,所有人都在说「这次不一样,有基本面支撑」,结果 2022 年纳斯达克跌了 33%。

BTIG 预计,半导体板块可能会出现 25% 至 30% 的修正,这将使费城半导体指数回落至其 50 日移动平均线附近。这个判断和我观察到的技术指标基本一致。

投资者应该怎么办?

说实话,我无法预测市场何时见顶。但有几个信号值得关注:

第一,当所有人都觉得「这次不一样」时,往往就是最危险的时候。第二,当半导体板块内部,数据中心相关股票涨了 230%,存储芯片类股票涨了超过 450% 时,获利盘的压力会越来越大。

第三,也是最关键的,美联储的政策转向存在不确定性。虽然市场现在预期年内不会加息,但如果通胀数据意外走高,一切可能瞬间反转。

我的建议是:如果你已经赚了不少,可以考虑逐步锁定利润。如果你还在犹豫要不要追高,不妨等等回调。因为即使这次真的不一样,市场也会给你更好的买入机会。

记住,2000 年互联网泡沫破裂前,很多人也觉得「这次不一样」。结果呢?纳斯达克从 5048 点跌到 1114 点,用了整整两年半才见底。而当年表现最好的那些股票,跌幅往往最大。

这次会不会重演?我不知道。但历史告诉我们,当涨幅超越 1999 年时,谨慎永远不是坏事。

A Group of Suzhou Engineers Unexpectedly Attain Financial Freedom

In Suzhou, a group of engineers from Lianxun Instruments, a leader in optical communication testing equipment, have achieved remarkable wealth after the company's IPO. Listed just two months ago on the STAR Market, the company's stock price surged approximately 30 times, making it the only A-share stock priced above 2,000 yuan. This surge created substantial fortunes for nearly 100 technical employees who held a collective 15.91% stake through employee stock ownership platforms, valued at over 36 billion yuan at the current market cap. Among them, nearly 40 became billionaires, while even the smallest holdings exceeded 5 million yuan in value. Founded in 2017 by Hu Haiyang, Yang Jian, and Huang Jianjun, Lianxun Instruments was established to address China's reliance on foreign high-end testing instruments. The company grew rapidly with a strong focus on R&D, where technical staff make up nearly 80% of its workforce. Early implementation of employee stock plans helped retain this core talent. The company's explosive growth is fueled by booming AI computing demand, with clients including major global optical module leaders. Its revenue skyrocketed from 276 million yuan in 2023 to 1.194 billion yuan in 2025, turning a profit in 2024. The IPO has also generated massive returns for early investors, including Suzhou's state-owned capital, which saw a hundredfold return. This story reflects a broader trend in China's markets, where technology firms in AI, semiconductors, and optics are creating new wealth, rewarding engineers and technical teams who are now central to modern capital-driven success stories, marking a shift from previous eras dominated by internet and real estate tycoons.

NVIDIA's Annual 'Most Dangerous' Paper: AI Self-Replicating Code, Unlimited Leveling and Evolution

NVIDIA's "Red Queen Gödel Machine" (RQGM) paper proposes a potentially groundbreaking AI self-evolution framework. It breaks from the long-stalled concept of the "Gödel Machine," which required mathematically proven beneficial self-modifications, by adopting an evolutionary approach. The core, and most striking, innovation is that the AI does not just evolve its own code in a static environment. Instead, it co-evolves both the "student" (the task-performing agent) and the "examiner" (the evaluation system that judges it). This creates a dynamic, recursive self-improvement loop inspired by the biological "Red Queen Hypothesis"—where continuous adaptation is needed just to maintain relative fitness. The mechanism operates in epochs. Within an epoch, a fixed examiner evaluates all candidate code variants. At epoch boundaries, a new, potentially more rigorous examiner can replace the old one, but only if it proves statistically superior on a held-out "ground truth" dataset. This "controlled utility evolution" aims to ensure progress is measurable and grounded. The paper demonstrates RQGM's effectiveness across three domains: 1. **Code Generation:** It achieved a 71.7% test-set pass rate (improving over a 69.9% SOTA) while using 1.35-1.72x fewer computational tokens. 2. **Paper Writing:** In a subjective task, the co-evolved writer and reviewer achieved a 40.5% acceptance rate by a fixed human panel, up from 21.8%. 3. **Math Proofs:** It evolved more accurate graders (at 3x lower cost) and higher-scoring provers. Notably, RQGM also mitigated a known LLM bias where AI reviewers favor AI-generated content. By specifically rewarding reviewers that correctly rejected AI-written papers from a historical pool, the evolved system achieved impartiality while maintaining 80% accuracy. The research has sparked significant discussion about the acceleration of Recursive Self-Improvement (RSI). Some, like Anthropic's Jack Clark, have predicted a high probability of highly autonomous, self-evolving AI emerging by 2028. The paper suggests that when an AI begins to design its own evaluators and push itself toward ever-higher standards in a recursive loop, it may be taking a fundamental step toward redefining intelligence and autonomy.

Apple and the Power Rebalancing with 'The Microns': Dissecting the Profit Ledger Behind the iPhone

The article analyzes the shifting profit dynamics and power balance between Apple and memory suppliers like Micron within the iPhone supply chain. It highlights a social media post criticizing Apple for raising iPhone prices while blaming memory chip cost increases, despite historically paying suppliers like Micron very little. An estimated iPhone 18 cost breakdown is referenced. Historically, memory was a minor cost component. In 2017's iPhone X, memory accounted for only about 1.6-2.3% of the price, with Apple capturing nearly 50% net profit. Over time, memory's share of the Bill-of-Materials (BOM) cost has grown significantly, reaching an estimated 12-15% for the iPhone 17 series. The core driver of this change is soaring demand for memory from the AI industry, particularly for High Bandwidth Memory (HBM) and AI servers, which is diverting production capacity and squeezing supply for consumer electronics. Memory manufacturers, after enduring periods of low profits, now hold greater pricing power. This is reflected in their recent strong financials, like Micron's 84.6% gross margin. Apple CEO Tim Cook initially described the memory price pressure as unprecedented in his 40-year career, later calling it a "once-in-a-century flood," before Apple announced price hikes across several product lines, causing a significant stock drop. Elon Musk echoed Cook's sentiment about the dramatic cost surge. The article concludes that the era of memory suppliers being at the mercy of Apple's pricing power has temporarily reversed, thanks to AI-driven demand. It notes Apple is reportedly seeking to diversify its supply chain, including exploring chips from China's CXMT.

Conversation with the Founder of 42 Macro: The Fed's 'Boiling the Frog Slowly' and the K-Shaped Economy

In a conversation with Anthony Pompliano, Darius Dale, founder of 42 Macro, discusses the Federal Reserve's monetary policy and the K-shaped U.S. economy. Dale characterizes new Fed Chair Kevin Warsh as a "dove in hawk's clothing," expecting the Fed to signal or enact policy tightening in the coming quarters to create room for later easing. He argues current economic signals, including high deficit spending, debt monetization, and credit growth, strongly indicate inflation is not on a credible path back to 2%, forcing the Fed to act. The discussion highlights the stark "K-shaped" economic reality. While top earners, buoyed by massive cash savings (up ~$8 trillion since pre-pandemic), continue robust spending, those at the bottom face severe financial strain, with delinquency rates on consumer loans reaching crisis-era highs. Dale attributes much of the current social and political anxiety to this divergence, driven by the "Cantillon effects" of monetary expansion, which disproportionately benefits asset owners. He emphasizes that in this environment of "financial repression," individuals must participate in asset markets to avoid being left behind. On equities, Dale notes a rotation from the "Magnificent Seven" tech giants into broader AI-exposed companies, while warning that the tech giants' massive capital expenditure cycles could eventually puncture over-optimistic cash flow projections. Dale concludes by stressing that the core desire across all economic strata is simply the dignity to provide for one's family, a goal currently undermined by systemic policies that act as a "wealth siphon" from the bottom to the top.
