00 后「股神」爆仓，倒在结婚前

这是 一直夫妇 的第 913 篇文章

Aschenbrenner 阿申布伦纳可以说是「少年天才」，15 岁进入哥伦比亚大学，19 岁毕业，并且在本科毕业生中获得最高学术荣誉。毕业后，他加入 OpenAI，并快速成长为团队的核心成员。

2024 年，他创立对冲基金 Situational Awareness LP。有报道称，自成立以来，该基金的累计收益曾超过 1000%。因此他一度被称为「AI 股神」。2026 年 7 月，全球芯片和 AI 股票大幅下跌，阿申布伦纳的高杠杆迅速从摇钱树变成了催命符。在 Aschenbrenner 大婚前，他不得不将大部分持仓低价出售给 Citadel。

On Thursday, the San Francisco fund Situational Awareness, founded by a former OpenAI researcher with no professional investing experience, was forced to sell the bulk of its public holdings to a bigger rival after its investments soured and it faced a raft of margin calls from lenders.

1️⃣ sour

熟词生义

这是我们很熟悉的形容词，表示「酸的」。馒头发酸、饭菜发酸，意味着东西腐坏变质。于是后来 sour 长出动词词性，表示关系、情况等「变坏，恶化」。its investments soured 字面意思是说「这只基金的投资表现恶化了」，实际是说「投资开始亏损了」，没有获得预期回报，反而出现损失。

An unhappy childhood has soured her view of life.

不幸的童年扭曲了她的人生观。

2️⃣ a raft of

金牌写作短语

raft 是「木筏」。我之前去桂林的时候，江上飘了很多木筏，并不是孤零零一个。大家去其他地方游玩，也看到过类似场景。我们可以根据这个联想，记住词组 a raft of，表示「大量，许多」。我们可以用这个短语替换 many, a great many 等。来看《经济学人》。

A raft of automated tools smooths the process. “It’s not quite as simple as designing a custom T-shirt on Etsy,” says Malcolm Penn, who runs Future Horizons, another chip-industry analyst.

大量自动化工具让生产过程变得更顺畅。「倒也不像在Etsy上设计定制T恤那么简单。」另一家芯片行业分析公司Future Horizons的主管马尔科姆 · 佩恩说。

In a matter of days, the aggressively AI-concentrated fund went from being the envy of Wall Street — Situational was reportedly up more than 400% this year — to needing a bailout by a larger rival, a dramatic turn that’s deepening investors’ anxiety about the sustainability of the AI momentum trade and the risks of leaning on leverage.

3️⃣ lean on

金牌写作短语

我们之前在「考研精度训练营」学习时补充过这个短语，表示「依赖，依靠」某人、某物。用腻了 depend on 的各位不妨在写作中换上 lean on。此外，rest on 也表示此义。同样是《经济学人》。

Prince Muhammed will lean on his kingdom’s oil riches to pay for NEOM at an initial cost of $319bn.

穆罕默德王子将依靠沙特的石油财富为 NEOM 支付3190亿美元的初始成本。

03

But much of what ailed the firm is not unfamiliar to investors around the world, as they’ve sought to amplify their exposure to the parabolic gains in AI-related stocks. Situational borrowed heavily from lenders to buy tech stocks, a strategy that works well when the market is going up, and fails spectacularly when the mood sours.

4️⃣ amplify

六级 + 考研词汇

amplify 是动词，表示「放大」，如 amplify your voice 「放大你的声音」。此外，它还有「增强」的意思。现实情况可能会 amplify your fears about the future「加剧对自己未来的恐惧」。2023 年 12 月的六级阅读有个长句。

The team finds that the majority of editors in top psychology and neuroscience journals are male and based in the United States: a situation that may be amplifying existing gender inequalities in the field and influencing the kind of research that gets published.

该团队发现，顶尖心理学和神经科学期刊的大多数编辑都是男性，而且身处美国。这种状况可能会加剧该领域现有的性别不平等，并影响最终能够发表的研究类型。

04

When economists warn about the risks of too much concentration in the stock market, this situation is what they’re talking about: The financial world is deeply interconnected, for better or worse, making one relatively small hedge fund’s bad day a problem for everyone – from mom and pop investors to asset managers overseeing funds in millions of 401(k)s.

5️⃣ for better or worse

即便不认识，但我们很快能通过字面意思推断出来，即「不管是好是坏」。这部分的意思是说，金融体系无论好坏都高度相互关联，因此，一家规模相对较小的对冲基金遭遇投资失败，也可能通过抛售资产、追加保证金和市场恐慌等途径影响所有人。
