突發:科技股市場近乎全線重挫

Breaking: Mayhem in the market 🫧

AI 導讀

科技股市場今日遭遇重挫,幾乎沒有公司倖免。前一天,晶片製造商及 CoreWeave 等新雲端公司大跌,Amazon、Apple 和 Google 等大型公司則反彈;市場有觀點認為,投資者或正轉向較能抵禦現金壓力的大型公司,或預期超大規模雲端服務商會減少 AI 數據中心的資本開支。

I am old enough to remember when I posted this yesterday on X and got a huge amount of shit for it, from Sabine Hossenfelder and a slew of bots and tech bros:

And, yesterday, after I posted it, the market was actually mixed, split hard between chipmakers and neocloud companies like CoreWeave that got hit hard (much as I anticipated), and big companies like Amazon, Apple, and Google that didn’t, and instead got a bounce.

One theory was that people were rotating out of the smaller neocloud companies, and into the bigger tech companies that could better weather the cash crunch:

Another similar theory was the hyperscalers were up because (in light of the public resistance to data centers which came clear on Tuesday) investors thought that the hyperscalers might finally settle down on their wild CapEx expenditures:

Fascinating - Josh at Epoch thinks that hyperscaler stocks are up because investors want company management to spend less capex dollars building AI data centers and the election results will force them to comply

@billyhumblebrag investors disagree with management on capex and want them to build fewer data centers

Today looks pretty different. It’s a slaughter. Almost no company is exempt.
