Nasdaq Rebounds 1.1% as Chip Stocks Snap an Eight-Day Slide, but Most US Stocks Fall; Brent Holds Near $110 as TASI Drops 0.65% and Qatar Stays at a Six-Year Low

Takeaway: On Tuesday 20 October 2026 (Asia/Dubai), markets are weighing a narrow, tech-led bounce on Wall Street against fresh Gulf security headlines. On Monday the Nasdaq rose 1.11% to 26,430.89 and the S&P 500 gained 0.41% to 7,690.73 as chipmakers snapped an eight-day losing streak, but the Dow slipped 0.07% to 51,966.03 and most US stocks outside AI and tech fell. The 10-year Treasury yield climbed to about 5.14% and European stocks dropped more than 1% after violent protests in France. Brent settled at $109.55 (−0.3%) after swinging between roughly $107 and $110, while the expiring November WTI contract rose 2.2% to $103.66. In the Gulf, TASI fell 0.65% to 10,123.62 as banks weighed, Qatar closed flat at 8,632.66, its lowest in more than six years, and Kuwait’s All-Share lost 0.42% to 8,406.78. This morning Asian shares are lower, led by a 2.8% drop in Korea’s Kospi, and US futures are little changed.

What happened

1) US equities: a chip rebound that carried the indexes, not the market

Monday 19 October 2026 close (AP; CNBC; Reuters): S&P 500 7,690.73 (+31.29 / +0.41%), Nasdaq Composite 26,430.89 (+290.85 / +1.11%), Dow 51,966.03 (−36.38 / −0.07%), Russell 2000 2,728.30 (+6.93 / +0.3%).

Cleveland-Cliffs jumped 16% on stronger-than-expected results, while Ameriprise fell almost 4% after a Bank of America downgrade (Reuters; CNBC).
Sectors: seven of the S&P 500’s 11 sectors closed lower. Consumer discretionary led with a 2.7% gain and technology added 1.2%, while utilities fell 2% and real estate 1.2% (Reuters). Declining issues outnumbered advancers by 1.69 to 1 on the NYSE (Reuters).

2) Rates, Europe and the dollar

The 10-year Treasury yield rose to about 5.14% from 5.09% late Friday, as oil erased early losses (AP; WSJ). It held near 5.14% in Asian trade on Tuesday (Bloomberg via The Business Times).
Europe fell after a weekend of violent cost-of-living protests in France and clashes in Milan: Paris’s CAC 40 lost 1.1% to 7,868.05, Milan’s FTSE MIB 1.6%, Frankfurt’s DAX 1.2% and London’s FTSE 100 1.1% (AFP).

3) Oil: a sanctions waiver against Gulf supply risk

Monday settlement (Reuters; WSJ): Brent $109.55 (−$0.31 / −0.3%), after falling more than $3 earlier in the session; it touched $110.70 at one point, its highest since 20 May (Reuters via CNBC). The November WTI contract, which expires today, rose 2.2% to $103.66 on thin volume, its highest settlement since 15 September, while the more actively traded December WTI contract fell 0.5% to $98.54 (Reuters; WSJ).
Prices fell early after President Trump’s order waiving some Russia-related sanctions and tariffs, though Trump has said a final decision has not been made (Reuters via CNBC). They recovered after Yemen’s Houthis said they had attacked Saudi energy, airport and military targets, including an Aramco facility in Yanbu and the Shaybah oilfield; Saudi authorities did not immediately confirm the claims and Reuters could not verify them. Iran’s Revolutionary Guards also said a tanker caught fire and exploded after hitting a naval mine in the southern Strait of Hormuz on Sunday (Reuters).
Tuesday in Asia, Brent traded either side of Monday’s settle: it was down 0.45% at $109.06 shortly after the open (Reuters via CNBC) and later up 0.2% at $109.74, with WTI at $103.82 (AFP).

4) Gulf equities: Monday 19 October

TASI 10,123.62 (−66.15 / −0.65%), with turnover of about SAR 3.6bn (Argaam; Arab News). Al Rajhi Bank fell 1% to SAR 60.55 and Saudi National Bank 1.6% to SAR 36.98, while Aramco was unchanged at SAR 25.80 (Argaam; Reuters). Decliners far outnumbered gainers, and insurance (−2.41%) and media (−3.88%) were among the weakest sectors, while utilities rose 0.84% (Argaam; Arab News).
Qatar (QE) 8,632.66 (−0.91 / −0.01%), effectively flat but at its lowest in more than six years (QNA via Al Arab; Reuters). 11 stocks rose and 37 fell, on turnover of about QR377.2m (QNA via Al Arab).
Kuwait All-Share 8,406.78 (−35.28 / −0.42%); Premier Market −0.34% to 8,840.52, Main Market −0.80% to 8,418.72; value traded about KD68.9m (QNA; Reuters).

5) Asia and futures: Tuesday morning

Monday close: Japan’s Nikkei 225 fell 0.6% to 64,916.70 and Shanghai rose 0.4% to 3,730.92, while Korea’s Kospi rebounded 1.8% (AFP; AP). Hong Kong was closed for a holiday.
Tuesday: tech led losses across Asia. Korea’s Kospi was down about 2.8% after falling more than 4% at one point, as SK Hynix and Samsung slid; the Nikkei was down 0.6% at 64,512.35 at the midday break, and Hong Kong’s Hang Seng was down about 1% (AFP; AP).
US stock futures were little changed in Asian trade (Bloomberg via The Business Times).
China kept its one-year loan prime rate at 3.0% and five-year rate at 3.5%, unchanged for a 17th straight month (Reuters via Investing.com; Xinhua).

Why it matters for Gulf + US-focused Arab traders

A bounce is not yet a recovery: Monday’s gains came from a small group of heavyweight AI and chip stocks while most of the market fell and yields rose. This week’s big-tech results, starting with Netflix today and Meta and Tesla on Wednesday, will show whether the rebound can broaden.
Gulf risk is back in the oil price: Brent gave up more than $3 on a Russia sanctions headline and then won it back on reported attacks on Saudi energy sites. In this market, confirmed supply effects matter more than the first reaction to a headline.
Gulf breadth is weak: TASI fell even with Aramco flat, as banks and smaller stocks weighed, and Qatar is holding at six-year lows. Index levels alone understate how many stocks are under pressure.

What’s ahead

Today (Tuesday): US housing starts and building permits for September (16:30 Asia/Dubai) and pending home sales (18:00 Asia/Dubai). GE Aerospace, General Motors, RTX, 3M and Northrop Grumman report before the US open; Netflix, United Airlines, Capital One and Intuitive Surgical after the close (eOption). SpaceX also reports third-quarter results today (SpaceX; Reuters). The November WTI contract expires today (Reuters).
Wednesday: Meta, Tesla, IBM, Texas Instruments and Lam Research after the US close; AT&T before the open; a US$13bn 20-year Treasury auction (eOption).
Thursday: US weekly jobless claims (16:30 Asia/Dubai); Procter & Gamble and American Airlines before the open (eOption).
Friday: S&P Global flash PMIs for October (17:45 Asia/Dubai) and the final University of Michigan sentiment survey (18:00 Asia/Dubai); American Express before the open (eOption).
Next week: The Fed meets on 27–28 October, with the decision on 28 October (Reuters via CNBC).

Short educational angle: reading market breadth when the index and the market disagree

An index like the S&P 500 is weighted by market value, so a handful of very large companies can lift it even when most stocks fall. Monday was a clear example: the S&P 500 rose 0.41%, yet seven of its 11 sectors closed lower and declining shares outnumbered advancing ones by about 1.7 to 1 on the NYSE (Reuters). AP noted that Nvidia, the largest stock by market value, was one of the strongest forces behind the gain. Breadth measures, such as the advance/decline count, the number of sectors rising, or new highs versus new lows, help show whether a move is broad or narrow. A rally led by a few heavyweights can continue, but it is more exposed if those few stocks stumble, which is why this week’s big-tech results matter. The same check works in the Gulf: on Monday TASI fell only 0.65%, but decliners far outnumbered gainers. This is educational framing only, not a forecast or a recommendation on any trade.
