Did the Market Just Prove It Can Survive a Chip Meltdown?

NEW YORK — U.S. equities shook off a brutal open Thursday to close broadly higher, with the Dow Jones Industrial Average posting its strongest session in weeks — gaining 556 points — even as a global semiconductor rout, two consecutive hotter-than-expected inflation reports, and a sobering post-earnings slide in TSMC threatened to pull the entire tape lower.

The final scoreboard: the S&P 500 closed at 7,744.00, up 0.33%. The Dow settled at 52,177.00, up 1.08%. The Nasdaq Composite eked out a 0.08% gain to 26,713.00, barely clawing back from a sharply negative open. The Russell 2000 led all major indexes, rising 1.38% to 2,767.00 — a signal that whatever was driving Thursday’s bid was decidedly not concentrated in large-cap technology.

How the Tape Turned: From Freefall to Finish Line

Thursday’s session opened in the red — emphatically so. The Nasdaq and S&P 500 gapped lower at the bell, carrying over Wednesday’s CPI-driven selloff and compounding it with an overnight global chip rout that saw South Korea’s Kospi index plunge 8%, with Samsung Electronics and SK Hynix cratering 9% and 11%, respectively. For the first hour, the question wasn’t whether the market would fall — it was by how much.

The pivot came mid-morning, and it wasn’t driven by any single headline. Despite the PPI reading coming in hot — the second consecutive inflation surprise in as many sessions — Treasury yields did something unexpected: they fell. The 10-year dropped sharply to approximately 5.05%, down from 5.329% Wednesday morning. The U.S. dollar also softened. That combination gave rate-sensitive sectors room to breathe and handed buyers a reason to step in.

The Nasdaq tested the unchanged line before ultimately managing a marginal gain. The real outperformance, though, came from the Dow’s 17-of-30 advancing components and the Russell 2000’s broad-based surge — a profile that reads less like a tech recovery and more like a deliberate rotation out of growth and into value, cyclicals, and defensives. The market’s internal split has been widening all week, and Thursday made that fracture impossible to ignore.

The Sector Scorecard: Healthcare Leads, Chips Lag

The sector rotation Thursday was not subtle. Healthcare (XLV) hit all-time highs, and Consumer Staples (XLP) caught a meaningful bid on retail strength — both sectors reflecting the kind of defensive repositioning that tends to follow prolonged uncertainty about monetary policy direction. Financials (XLF) also posted solid gains, as did Materials (XLB), lifted by a rebound in metals.

Technology and semiconductors remained the session’s anchor. The chip selloff that began earlier this week showed no sign of reversing at the sector level, even as TSMC’s earnings — covered in detail below — were objectively strong. The divergence between what the numbers say and what the stocks are doing in semiconductors is the market’s central unresolved tension heading into next week.

In fintech, Bank of America downgraded PayPal (PYPL) to Underperform from Neutral, slapping a $53 price target on the stock and flagging a weak Q3 setup. The call added another layer of pressure to a sector already navigating a difficult macro backdrop of elevated rates and consumer spending uncertainty.

TSMC’s Blowout Quarter That the Market Didn’t Want to Buy

Taiwan Semiconductor Manufacturing reported one of the most impressive quarters in its history Thursday morning — and still closed lower. That disconnect tells traders nearly everything they need to know about current sentiment toward the AI infrastructure trade.

The numbers: Q3 EPS of $4.60 per ADR unit, beating the $4.45 consensus by $0.15. Revenue of NT$1,494.24 billion. Net income up 68.7% year-over-year. Revenue up 50.9% year-over-year. Gross margin at 66.4%, operating margin at 58.7%. High-performance computing — the AI-driven segment — surged 22% quarter-over-quarter to represent 68% of total revenue. Advanced technology nodes (7nm and below) accounted for 79% of wafer revenue, with 2nm contributing 8% and 3nm at 33%.

Management guided Q4 2026 revenue to $52.3–$54.3 billion — a 14% sequential increase — and raised its full-year 2026 growth outlook to approximately 44% year-over-year, citing supply-constrained AI demand that shows no sign of softening.

Shares still fell 3.2%. Analysts pointed to elevated valuation, the cost drag from the expensive N2 and overseas fabrication expansions, and expected gross margin dilution as headwinds that the guidance failed to fully offset. Reports that Anthropic’s quarterly revenue jumped 45% sequentially offered little reprieve for the sector — a data point that would have been rocket fuel for chip stocks six months ago but landed with a thud Thursday.

The question worth sitting with: if a company growing earnings at nearly 69% year-over-year, guiding up 44% for the full year, and operating at 58.7% operating margins can’t hold a bid, where exactly is the floor for semiconductor valuations right now? There may not be a clean answer — but traders who assume TSMC’s results prove the AI trade is intact are reading a different chart than the one the stock is drawing.

What Thursday’s Close Sets Up for Friday

The session’s most actionable setup heading into Friday isn’t a stock — it’s the 10-year Treasury yield. At 5.05%, it sits at a level that, if it holds, provides a plausible tailwind for the defensive rotation that drove Thursday’s bid. The market has been repricing Fed expectations all week, and any yield bounce back above 5.15–5.20% would likely pressure the XLV and XLP trades that worked Thursday.

For the S&P 500, watch 7,718 — Wednesday’s close — as near-term support. A failure to hold that level on any morning weakness would signal Thursday’s recovery was a one-day relief trade rather than the beginning of a genuine stabilization. On the upside, 7,800 remains the level bulls need to reclaim to declare the recent inflation-driven pullback contained.

The semiconductor space remains the market’s open wound. The bifurcation between chip stocks and the broader market is now a structural feature of this tape, not a one-day anomaly. Traders should expect continued volatility in names with direct exposure to AI infrastructure spending until either yields stabilize convincingly or a large-cap chip name delivers results that the market actually rewards.

Thursday’s session closed the week’s most consequential open question — whether the market could absorb simultaneous pressure from hot inflation, a global chip rout, and a sell-the-news earnings reaction in its most important semiconductor name — with a provisional yes. The Dow’s 556-point surge and the Russell’s leadership suggest the broader market has more support beneath it than last week’s sentiment implied. Whether that support holds when Friday’s calendar and next week’s Fed commentary arrive is a different question entirely — and one the tape will answer without sentiment’s help.
