Asian Stocks Plunge on Chip Selloff as AI Spending Doubts Mount
There's nowhere to hide when they fall together
Mark
Why did SK Hynix fall so hard when its profits were up 557 percent?
Mimi
Because the market had already priced in something even better. When a company beats estimates but the beat isn't big enough, investors interpret it as a sign that growth is slowing. The real issue, though, was what those profits meant for the future—whether all the capital spending would actually pay off.
Mark
So this is about doubt in artificial intelligence itself?
Mimi
Not doubt in AI. Doubt in whether the spending makes economic sense. There's a difference. Everyone believes AI will matter. The question is whether Alphabet spending $205 billion and SK Hynix spending $31 billion will generate returns that justify those outlays, or whether they're all building capacity that will sit half-empty.
Mark
And the Middle East fighting—how does that connect?
Mimi
It doesn't, except that it does. Oil prices jumped because of the Iran situation, which raises inflation concerns. The Fed is meeting this week. If inflation stays sticky, they might raise rates. That makes every expensive stock—especially tech—less attractive. It's another reason to sell.
Mark
Is this a correction or a crash?
Mimi
It's a rotation. Money is moving out of semiconductors and into energy, financials, consumer stocks. That's orderly, not panicked. But orderly rotations can accelerate if the narrative shifts. If Microsoft or Meta report disappointing guidance on Wednesday, orderly becomes something else.
Mark
What are investors watching for now?
Mimi
Earnings from the big tech companies, the Fed decision, and whether oil prices stay elevated. If energy stocks keep rallying and tech keeps falling, the market is telling you it believes inflation is coming back. That changes everything about how you value growth stocks.
Mark
So we're back to inflation fears?
Mimi
We never really left them. We just got distracted by AI for a while.
El Pulso
- South Korea's Kospi collapsed 11% for a second straight day — a historic back-to-back rout driven by chip giants SK Hynix and Samsung, whose combined weight left investors with no place to shelter.
- A 557% profit surge at SK Hynix was met with a 17% stock decline, exposing a market no longer asking whether AI is real, but whether the hundreds of billions being spent on it will ever make financial sense.
- The selloff radiated outward — MSCI Asia Pacific hit its lowest since April, Nasdaq 100 futures extended a five-day losing streak, and European markets braced for contagion as tech earnings season entered its most critical week.
- US-Iran military exchanges pushed Brent crude above $88 a barrel, reviving fears of Strait of Hormuz disruption and inflation pressure just as the Federal Reserve prepares its interest rate decision.
- Investors are rotating rapidly — out of semiconductors and into energy, financials, and consumer stocks — with the Nasdaq 100 teetering on the edge of a technical correction as Microsoft, Meta, Apple, and Amazon prepare to report into the storm.
From Seoul to Wall Street, markets are confronting a question that prosperity tends to defer: what happens when belief outruns evidence? South Korea's chip giants reported extraordinary profits and were punished for it, as investors began to doubt whether the vast sums being committed to artificial intelligence infrastructure would ever find their return. Simultaneously, renewed military confrontation between the United States and Iran sent oil surging past $88 a barrel, raising the specter of inflation at precisely the moment the Federal Reserve prepares to speak. Two separate anxieties — one about the future of technology, one about the stability of the present — arrived together, and markets had nowhere to stand.
The selling began in Seoul and spread. South Korea's benchmark index fell 11 percent on Wednesday — the second consecutive day of identical losses — as semiconductor stocks led a collapse that had no precedent in the index's history. SK Hynix reported a 557 percent surge in quarterly profits. Investors sold it down 17 percent anyway. Samsung Electronics fell 12 percent ahead of its own results. When the two companies that define the index move together in the same direction, there is no diversification, no shelter. "There's nowhere to hide when they fall together," one analyst observed.
The question driving the selloff had shifted. Markets were no longer debating whether artificial intelligence would matter — they were asking whether the money being spent on it would ever make sense. Alphabet had raised its annual capital spending forecast to as much as $205 billion. SK Hynix alone had committed $31 billion for 2026. These were not tentative wagers but massive, multi-year bets on infrastructure that AI companies believed they would need. The market had begun to wonder aloud whether the returns would ever arrive — or whether the spending was circular, companies building capacity that only other companies making the same bet would fill. That concern had moved from whisper to price action.
A separate anxiety was pushing oil in the opposite direction. After the United States said it had intercepted an Iranian attack and struck back, Brent crude jumped more than 4 percent to trade above $88 a barrel. Attention snapped back to the Strait of Hormuz, through which much of the world's oil flows. Any disruption there could stoke inflation — an unwelcome development with the Federal Reserve set to announce its rate decision the same day, and markets already uneasy about the possibility of a surprise hike.
The two forces created a disorienting backdrop. Investors rotated out of technology and into energy, financials, and consumer shares. A gauge of chipmakers fell 4.5 percent on Wall Street, pushing the Nasdaq 100 toward a technical correction. Microsoft, Meta, Apple, and Amazon were all preparing to report earnings into this atmosphere of doubt. The unspoken hope was that resilience elsewhere in the economy might carry markets while technology worked through its reckoning. But hope and price action, as the week was demonstrating, are rarely the same thing.
The selling started in Seoul and rippled outward. South Korea's main stock index fell 11 percent on Wednesday, compounding an identical drop from the day before—a two-day collapse that put the benchmark on track for its worst consecutive performance on record. The culprit was semiconductor stocks, and the wound was self-inflicted by the very companies that had been celebrated as engines of artificial intelligence growth.
SK Hynix, one of the world's largest chipmakers, reported quarterly profits that had surged 557 percent. By any traditional measure, this was extraordinary. Investors sold the stock anyway, sending it down 17 percent. Samsung Electronics, the other pillar of South Korea's chip industry, fell 12 percent in anticipation of its own earnings report due Thursday. "Given the weight of SK Hynix and Samsung on the Kospi, there's nowhere to hide when they fall together," said Josh Gilbert, lead analyst for Asia Pacific and the Middle East at Etoro Ltd. When the two largest companies in your index move in the same direction, there is no diversification, no shelter.
The rot spread across Asia. The broader MSCI Asia Pacific Index dropped roughly 2 percent, reaching its lowest point since mid-April. Nasdaq 100 futures fell 0.9 percent, extending a five-day losing streak—the longest for that tech-heavy gauge all year. European shares were bracing for weakness at the open. The question driving the selloff was no longer whether artificial intelligence would matter. It was whether the money being spent on it would ever make sense.
Alphabet had recently raised its capital spending forecast to as much as $205 billion for the year. SK Hynix alone had committed at least $31 billion to capital spending in 2026, a record. These were not tentative bets. They were massive, multi-year commitments to build the infrastructure that AI companies believed they would need. But the market had begun to wonder aloud: what if they were wrong? What if the returns never materialized? What if the spending was circular—companies investing in capacity that would only be filled by other companies making the same bet? The concern had metastasized from whispers into price action.
Meanwhile, a different kind of uncertainty was pushing oil higher. The United States said it had intercepted an Iranian attack on its troops and struck back at the Islamic Republic. Brent crude jumped more than 4 percent to trade above $88 a barrel, rebounding from its steepest three-day decline since April 2020. The renewed fighting in the Middle East refocused attention on the Strait of Hormuz, the narrow waterway through which much of the world's oil flows. Any disruption there could choke supply and fuel inflation—precisely the wrong moment, with the Federal Reserve preparing to announce its interest rate decision on Wednesday and markets already nervous about whether the central bank might surprise with a rate hike.
The semiconductor selloff and the oil surge created a disorienting backdrop. Investors were rotating out of technology stocks and into consumer discretionary, financial, and energy shares. A gauge of chipmakers slipped 4.5 percent on Wall Street, putting the Nasdaq 100 on the brink of a technical correction. The largest U.S. technology companies—Microsoft and Meta reporting Wednesday, Apple and Amazon on Thursday—were about to deliver earnings into this maelstrom of doubt. "If sectors outside semiconductors deliver resilient earnings this season, investors may find it easier to shift their attention elsewhere," said Ikuo Mitsui, a fund manager at Aizawa Securities Co. The unspoken hope was that the rest of the economy might prove sturdy enough to carry the market while technology stocks worked through their reckoning. But hope and price action are not the same thing.
