The moment that assumption cracked, money began flowing toward safer ground.
在美國就業數據強勁引發聯儲局加息憂慮之後，亞洲市場於週一迎來了一場跨越太平洋的信心動搖。人工智能熱潮所積累的估值溢價，在利率預期轉向的瞬間顯得格外脆弱——這提醒我們，市場的繁榮往往建立在對未來的假設之上，而非當下的現實。從香港到首爾，投資者以沽售行動重新丈量風險的邊界，而這場重估究竟是短暫的修正，還是更深層的轉折，仍是懸而未決的問題。
- 美國強勁就業報告打破了低息環境將持續的核心假設，令科技股估值邏輯在一夜之間動搖。
- 恒生指數跌逾1.5%，上海綜合指數跌2.2%，而中國科技及半導體相關指數跌幅更深達3至5%，顯示拋售最集中於人工智能供應鏈。
- 日本日經指數單日暴跌近4%，創三個月最大跌幅；首爾股市更觸發熔斷機制，交易一度暫停二十分鐘。
- 中芯及光模塊龍頭中際旭創等個股領跌，曾是AI行情旗手的公司，如今成為市場恐慌的風向標。
- 投資者目光轉向聯儲局政策信號與中東地緣局勢，等待方向性指引，市場情緒仍處於高度警戒狀態。
週一早晨，香港與上海的交易屏幕同時染紅。恒生指數下跌379點，跌幅1.52%，為亞洲全日的廣泛撤退定下基調。觸發這場拋售的，是週五公布的美國就業數據——數字過於強勁，令市場擔憂聯儲局將重啟加息，而這一預期足以瓦解科技股數月來積累的漲幅，並終結華爾街連續九週的升勢。
中國內地市場的跌幅更為慘烈。上海綜合指數開盤跌2.2%，滬深300跌2.35%，但重創集中於科技板塊：深圳成指跌逾3%，創業板指跌3.48%，科創50開盤跌近5%，半導體板塊整體跌幅超過五個百分點。曾作為中國AI雄心象徵、為英偉達供應光模塊的中際旭創，開盤即跌4%——這家剛剛躍升為滬深300第一大權重股的公司，其地位此刻顯得岌岌可危。
這場恐慌以驚人的速度蔓延至整個亞洲。東京日經指數單日暴跌2547點，跌幅3.83%，創三個月最差表現，中東局勢再度緊張更加劇了市場的不安。首爾局面尤為混亂，韓國綜合指數午前跌幅一度擴大至8.4%，觸發熔斷機制，全場交易暫停二十分鐘。
真正改變的，並非人工智能產業的基本面，而是風險的計算方式。低息環境下，投資者願意為高增長潛力支付溢價；一旦加息預期重燃，這套邏輯便迅速逆轉，資金開始流向更安全的資產。市場現在面對的核心問題是：這究竟是一次短暫的技術性調整，還是亞洲科技股更深層重新定價的開端？
Monday morning in Hong Kong and Shanghai opened to red screens across the board. The Hang Seng Index fell 379 points—a 1.52 percent drop that set the tone for a day of broad retreat across Asia. Investors had woken to a simple but unsettling fact: the artificial intelligence rally that had powered markets higher for months was suddenly looking fragile, and the reason was sitting in Friday's US jobs report.
The numbers from America had been strong—too strong, in the eyes of traders who feared the Federal Reserve would respond by raising interest rates. That prospect alone was enough to unwind months of accumulated gains in technology stocks, the very sector that had driven the AI boom. Wall Street's nine-week winning streak had ended Friday with the largest single-day decline in tech stocks since April 2025. Now that selling pressure was spreading westward across the Pacific.
In mainland China, the damage was steeper. Shanghai's Composite Index opened down 2.2 percent. The blue-chip CSI300 fell 2.35 percent. But the real carnage was in the technology-focused indices: Shenzhen's Component Index dropped 3.13 percent, while the ChiNext Index—a barometer for China's most innovative companies—fell 3.48 percent. The Star50, a tech-heavy benchmark, opened nearly 5 percent lower. Semiconductor shares, which had been riding the AI wave, slumped more than five percent across the board.
One company in particular illustrated the reversal. Zhongji Innolight, which supplies optical components to Nvidia and has become a bellwether for China's AI ambitions, fell four percent at the opening bell. The company had recently become the single largest weight in the CSI300 index—a position of prominence that now looked precarious. The China enterprises index dropped 1.66 percent, while the tech index fell a more modest 0.31 percent, suggesting that the heaviest selling was concentrated in the semiconductor and AI supply chain stocks that had led the rally higher.
The contagion spread across Asia with remarkable speed. In Tokyo, Japan's Nikkei share average sank 2,547 points—a 3.83 percent decline, the worst day in three months. Traders there cited not only the technology valuation concerns but also a fresh flare-up in Middle East hostilities, adding another layer of uncertainty to an already nervous market. In Seoul, the situation turned chaotic. The Kospi index fell 4.71 percent before noon, but then dropped another 8.4 percent to 7,477, triggering an automatic circuit breaker that halted all trading for twenty minutes.
What had changed between Friday's close and Monday's open was not the underlying health of the AI industry or the companies driving it. What had changed was the calculus of risk. As long as interest rates seemed likely to stay low, investors were willing to pay premium prices for growth stocks with uncertain near-term profits but enormous long-term potential. The moment that assumption cracked—the moment a strong jobs report suggested the Fed might tighten monetary policy—that calculus inverted. Money that had been chasing the highest-growth opportunities began flowing toward safer ground. The question now was whether this was a brief correction or the beginning of a more sustained repricing of technology stocks across the region.
Notable Quotes
Investors grew concerned over the sustainability of the AI rally after strong US jobs data fuelled fears of Federal Reserve rate hikes— Market analysis from the trading day
The Hearth Conversation Another angle on the story
Why did a US jobs report cause such immediate selling in Hong Kong and Shanghai?
Because strong jobs data signals inflation pressure, which makes the Federal Reserve more likely to raise interest rates. Higher rates make future profits worth less in today's dollars, which hits growth stocks hardest—and tech stocks are the purest growth play.
But the AI industry itself hasn't changed. The chips still work. The companies still exist.
True. But markets aren't pricing what exists today. They're pricing what they believe will exist in five or ten years, and at what discount rate. When that discount rate changes overnight, the price can move violently even if nothing fundamental has shifted.
Why did Zhongji Innolight fall so hard when it's just one company?
Because it's not just one company—it's a symbol. It's the biggest weight in China's main stock index. When it falls, it drags the whole index down. And it's an Nvidia supplier, so it's directly exposed to global AI sentiment. When global investors get nervous about AI valuations, they sell the supply chain first.
The Seoul market actually halted trading. That seems extreme.
Circuit breakers exist for exactly this reason—to prevent panic selling from becoming a stampede. When the Kospi fell 8.4 percent in a single session, the automatic halt kicked in. It gives traders time to think instead of just react. Whether it helps or just delays the inevitable is debatable.
Is this the end of the AI rally?
No one knows. This could be a healthy correction—a chance for valuations to reset to more sustainable levels. Or it could be the first domino. What matters now is what the Fed actually does. If they signal patience, money flows back into tech. If they signal rate hikes are coming, this selling could accelerate.
