Key Highlights

● Citi downgraded US stocks and global technology to neutral.

● It upgraded European equities.

● The forward price-to-earnings ratio of 17.7 sat below the five-year average of 19.8.

Monday, November 9, 2026, was a day for bulls. The S&P 500 jumped 173.08 points to close at 7,549.94, its best session since April 8, and the Nasdaq-100 posted its best day since March 31, according to news reports. Yet Citi struck a more cautious note.

The bank downgraded US stocks and global technology to neutral and upgraded European equities, reports said. A neutral rating generally signals that strategists expect a market to perform roughly in line with others, rather than outperform.

The positioning worry

Citi's concern centred on how investors are positioned. Strategist Beata Manthey said: "We worry that positioning on key indices, such as the Nasdaq, could reset lower into net-short territory."

Net-short means that, on balance, investors are betting on declines rather than gains. The strategist's warning suggests Citi sees a risk that, after a long period of heavy enthusiasm for US tech, sentiment could swing further toward pessimism, even after Monday's bounce.

Why the timing stands out

The call came after a bruising stretch. The S&P 500's prior week was its worst since April 2025, according to market coverage. The Nasdaq-100 had just posted its fourth straight weekly decline, according to market reports. Market data headlined on November 5 that the Nasdaq had tumbled "into correction territory on AI tech wreck."

Monday's rebound was broad, with all 11 S&P 500 sectors higher and 423 index members rising, reports said. Chipmakers such as Advanced Micro Devices (NASDAQ:AMD), Applied Materials (NASDAQ:AMAT) and Lam Research (NASDAQ:LRCX) jumped sharply. But one day of gains does not settle the bigger questions facing the market.

The AI spending debate

Those questions centre on artificial intelligence. Goldman Sachs sees AI capital-spending growth peaking, and a research firm has warned that spending has outpaced operating cash flow, reports said. Politics is another wildcard: after Democrats won both chambers of Congress on November 3, reports said worries about restrictions on data centers.

Nvidia (NASDAQ:NVDA), the bellwether of the AI trade, slid to its lowest close since April 7, reports said, as its board opened an independent review involving CEO Jensen Huang. An Incline Investment Management strategist said: "There's still going to be a bit of reckoning as far as the AI trade is concerned."

The other side of the argument

Plenty of strategists see things differently. A JPMorgan strategist called the selloff "an intra-cycle reset and another deleveraging event in the AI supercycle," and an Oppenheimer strategist said it was "much too early to predict the failure of AI to gain traction," according to market data.

Fundamentals also look solid by some measures. With most S&P 500 companies reporting, more than eight in ten beat Earnings estimates, reports said, and its forward price-to-earnings ratio of 17.7 sat below the five-year average of 19.8. Market data noted, however, that the size of those beats has been small.

Strategists Split on AI Trade

Citi's call will be tested quickly. Tuesday's October Consumer Price Index is the last before the Federal Reserve's December 8-9 meeting, where traders see a hike as highly likely, according to news reports. A rate hike could weigh on richly valued tech stocks.

Nvidia's earnings on November 17 and Anthropic's planned Nasdaq listing, with a roadshow reported to start this week, will also shape sentiment toward US tech, and whether Citi's caution looks early or prescient.
