TL;DR

  • The Nasdaq AI chip selloff spread into Asia on Friday after TSMC's earnings and capital-spending plan failed to calm valuation concerns.
  • CNBC reported TSMC fell 7.29%, SoftBank closed 9% lower, Tokyo Electron lost more than 8%, and Advantest slid 7.2%.
  • The prior U.S. session gave traders the setup: CNBC reported the Nasdaq Composite fell 1.47% and the VanEck Semiconductor ETF dropped almost 4%.
  • This is a market-reaction story, not a weak-demand story. TSMC still reported strong profit, but traders are testing whether AI spending can keep supporting stock prices.

Nasdaq AI chip selloff: what happened

As of 08:00 UTC Friday, Nasdaq AI chip selloff pressure had rolled into Asia after a rough Thursday close for U.S. technology stocks. CNBC reported that the Nasdaq Composite fell 1.47% to 25,881.95, while the S&P 500 declined 0.51% and the Dow lost 105.67 points. Semiconductor shares carried much of the damage.

By Friday in Asia, the move had become more specific. CNBC reported that TSMC fell 7.29% in Taiwan, SoftBank closed 9% lower in Japan, Tokyo Electron lost more than 8%, and Advantest slid 7.2%.

Bloomberg's markets feed also framed the move as a deeper chip-stock rout, reporting that Taiwan stocks fell into a technical correction as TSMC's result stirred concern about heavy spending and future profitability. A technical correction usually means a drop of 10% or more from a recent high.

CNBC reported that TSMC's second-quarter profit rose 77.4% from a year earlier, with revenue and net income above estimates. The market reaction instead centered on capital expenditure, or capex, which means money spent on factories, equipment, and long-term production capacity. TSMC raised its full-year capex forecast to $60 billion to $64 billion from $52 billion to $56 billion.

In our internal ChartDojo catalyst logs, the shift was clear: traders moved from celebrating AI demand to questioning how much future spending is already priced into semiconductor shares. That is why this post treats the move as a live risk watch for index and chip-stock traders.

Why markets moved

Markets moved because the AI trade has become crowded. When a popular sector carries high expectations, even strong results can disappoint if investors wanted proof of wider margins, faster returns, or lower spending needs.

TSMC said AI-related demand remained very strong, according to CNBC. That matters because TSMC manufactures chips for major technology customers and sits near the center of the AI infrastructure buildout. Still, the company also raised its spending plan. For shareholders, that created a harder question: how much cash must be reinvested before the AI boom becomes durable free cash flow?

That question spilled into U.S. and Asian stocks. CNBC reported the VanEck Semiconductor ETF fell almost 4% on Thursday. Arm Holdings dropped more than 5%, while Micron, Advanced Micro Devices, and Broadcom each lost more than 5%. U.S.-listed SK Hynix slumped more than 13%.

AI-linked shares had already made large gains this year. When momentum trades are crowded, a small change in the story can force funds to reduce exposure at the same time.

Implications for the most impacted trader cohorts

Index traders: the Nasdaq and S&P 500 are most exposed because mega-cap technology and semiconductor shares carry large weights. If chip weakness continues, rallies in defensive sectors may not be enough to keep the major indexes firm.

Semiconductor traders: TSMC, Nvidia-linked suppliers, memory names, and chip equipment makers remain in the direct line of fire. The first test is whether Friday's Asia selling turns into another U.S. semiconductor leg lower.

Futures traders: watch Nasdaq futures for follow-through before the U.S. open. A shallow bounce would suggest profit-taking after a crowded trade. A deeper break would point to a broader reset in AI risk appetite.

Crypto traders: Bitcoin and ether are not the center of this catalyst, but high-beta crypto can still react if the selloff becomes a general risk-off move. The clean read is whether crypto holds up while Nasdaq futures weaken.

Potential positives vs negatives from this catalyst

Potential positives:

  • TSMC's reported profit growth and revenue outlook still point to strong AI demand.
  • A quick stabilization in TSMC and SMH could turn the selloff into a valuation reset instead of a trend change.
  • Lower prices may help disciplined traders define cleaner risk levels after a crowded rally.

Potential negatives:

  • Higher capex can pressure margin expectations if investors doubt the payback period.
  • Chip equipment weakness in Japan and Taiwan suggests the concern is spreading through the supply chain.
  • If Nasdaq futures keep falling, risk managers may reduce exposure across other growth assets.

What could happen from here

Base case: the selloff stays concentrated in AI and semiconductor shares while the wider market looks for support. This path is confirmed if TSMC and SMH stabilize, Nasdaq futures hold above Thursday's low, and market breadth stops weakening. It is weakened if another group of megacap technology shares joins the decline.

Upside scenario: investors decide the spending concern is overdone because TSMC's demand outlook remains strong. Confirmation would be a rebound in TSMC, Tokyo Electron, SoftBank, and U.S. chip leaders, paired with a calmer Nasdaq open. This view fails if the bounce fades on heavy volume.

Downside scenario: the AI spending debate becomes a broader valuation reset. Confirmation would include another drop in the Nasdaq Composite, a fresh decline in SMH, and continued weakness in Asian chip equipment shares. This scenario loses force if buyers return quickly and the market rotates back into AI leaders.

What to watch next (next 24h)

  • Nasdaq futures before the U.S. cash open.
  • TSMC's U.S.-listed shares, SMH, Nvidia, Broadcom, AMD, Micron, Arm, and SK Hynix ADRs.
  • Japan and Taiwan chip-equipment shares for signs that selling is still spreading.
  • Analyst notes on TSMC's $60 billion to $64 billion capex plan and expected margin pressure.
  • Bitcoin and ether as a read on whether the move is staying inside equities or becoming a wider risk-off trade.

FAQ

Why did TSMC fall after strong earnings?

The selloff was tied less to current demand and more to future spending. CNBC reported TSMC raised its 2026 capex forecast, which pushed traders to question whether AI infrastructure investment is becoming expensive enough to pressure future returns.

Is this a warning for the whole stock market?

It can be, but only if semiconductor weakness pulls down the wider index tape. The first signal is Nasdaq futures. The second is whether selling spreads beyond chip stocks into other growth sectors.
