US Market Wrap 19 October: Nasdaq 100 Snaps Five Straight Declines and Only the Dow Slips

By The Edge Research Team

Four of the five US indices closed higher on Monday as investors bought back the artificial-intelligence names they sold last week. The Nasdaq 100 rose 1.17 percent and ended five straight declines. The Dow slipped 0.07 percent, the day’s only fall. The Treasury’s ten-year par yield rose six basis points to 5.15 percent. Brent crude traded 1.35 percent below Friday’s settlement at 108.38 dollars a barrel at our Commodities Wrap’s 11:00 GMT reading, and the session’s settlements follow in that wrap’s evening update.

The rebound comes before the proof

Investing.com’s closing report framed the session as a bounce from Wall Street’s worst week since late June, with attention turning to the quarter’s first heavy run of results. The Nasdaq Composite rose 1.11 percent to 26,430.89. The S&P 500 added 0.41 percent to 7,690.73, and the small-cap Russell 2000 rose 0.25 percent to 2,728.30. The gain won back a fifth of the 1,695.60 points the Nasdaq 100 lost across its five-session slide. The index ended Monday 4.38 percent below its 9 October close. The slide these gains reversed had started with reports of advances by the Chinese memory-chip company CXMT: Micron lost 14.6 percent last week, Samsung Electronics 17.8 and SK Hynix 24.3. The Philadelphia semiconductor index went into Monday on an eight-session losing run, its longest since October 2008. CoreWeave, the largest of the specialized cloud providers, fell more than 25 percent last week as its bonds sold off, and Nvidia’s Jensen Huang said the company did not need a backstop. Reports of slowing revenue growth at the AI developer Anthropic added to the unease. King Lip of BakerAvenue Wealth Management told Investing.com the AI trade “is moving from the promise phase to the proof phase,” with investors’ focus shifting “from ‘buy the theme’ to ‘show me the return.'” Brent Schutte, Northwestern Mutual Wealth Management’s chief investment officer, called the buildout’s financing increasingly rate-sensitive and some of it circular: “One company’s debt issuance becomes another company’s revenue.” The proof arrives quickly. SpaceX’s second set of results as a public company lands on Tuesday alongside Netflix’s numbers, and Meta Platforms and Tesla report on Wednesday. Elon Musk separately pledged one SpaceX share to every American child next year, a commitment the report valued at roughly 10.5 billion dollars.

Yields rise with France in the background

The bond market sold off while equities rallied. The Treasury’s par yield curve rose at every maturity from three months out, the two-year by three basis points to 4.77 percent and the ten-year by six to 5.15. The seven-year and the twenty-year also rose six basis points each, sharing the curve’s deepest move, and the thirty-year added five to 5.48. The gap between the two- and ten-year yields widened to 38 basis points from 35. The selling mirrored Europe’s, on the report’s account, where France’s ten-year borrowing costs surged after a weekend of violent protests over living costs and public services; AJ Bell’s Danni Hewson said markets could not simply shrug off the weekend’s destruction, and that the damage will weigh on an economy already paying heavily to borrow. Four of the eleven S&P 500 sectors rose. Consumer discretionary led at 2.73 percent, technology added 1.19 percent in a first gain after three declines, and communication services 0.28, while materials’ 0.08 percent rise was its third straight. Utilities fell 1.97 percent, the deepest sector fall, with real estate down 1.17 and the financials 0.79. The VIX closed 7.75 percent lower at 18.44.

Currencies, volatility and crypto

Quotes at 20:25 GMT, in fixed order; snapshots, not settlements, carrying the feed’s own session changes against Friday’s rows.

Asia, session of Monday 19 October

Carried whole from our Asia Market Wrap of 19 October 2026, its gainers then its losers in their published order; Hong Kong did not trade, so the Hang Seng has no row, and the Nifty row is the exchange’s own figure, as disclosed there.

Middle East, session of Monday 19 October

Carried whole from our Middle East Market Wrap of 19 October 2026, its gainers then its losers in their published order; seven of the nine closed lower, as disclosed there.

Europe, session of Monday 19 October

Carried whole from our Europe Market Wrap of 19 October 2026 in its published order, the shallowest fall first; all nine closed lower, as disclosed there.

Why it matters: The market bought back what it sold last week before any of the evidence it says it wants, since the results only start on Tuesday. That reads as positioning, not new information. Bonds were less forgiving: yields rose at every maturity past three months while stocks rallied, and the two groups that feel borrowing costs first, the utilities and real estate, sat at the bottom of Monday’s table with the banks. Equities are paying for the week’s earnings in advance, and the curve is charging more for the time it takes to deliver them. Of the 32 indices we published on Monday, Seoul’s Kospi led at 1.76 percent and Milan’s FTSE MIB lagged at 1.55 percent lower.

Outlook: Our Commodities Wrap of 19 October takes the session’s settlements in its evening update. Hong Kong returns from its holiday in Tuesday’s Asia wrap, while India’s market is closed for Dussehra. SpaceX and Netflix report on Tuesday, and Meta Platforms and Tesla on Wednesday, with the EIA’s weekly US inventories the same day. The Treasury’s next par yield curve publishes on Tuesday and will be read against Monday’s row.
