NEW YORK, Oct 16 : Stumbles in the market-leading AI trade are set to test investor confidence in the rally in the coming week as Wall Street focuses on quarterly results due from key players including Meta Platforms.
AI-linked stocks, central to the bull market that just marked its four-year anniversary, struggled in recent days, with sharp declines in shares of semiconductor companies and tech hardware firms such as Dell Technologies.
Meta, among the hyperscalers spending massively to build AI data centers, highlights the upcoming week of quarterly reports, along with semiconductor firms Lam Research and Texas Instruments.
"It certainly feels like the narrative in the market is a little bit jittery," said Garrett Melson, portfolio strategist with Natixis Investment Managers Solutions. "Clearly there's a lot of uncertainty around where AI stands right now."
Worries rippled through markets over risks tied to the financing of the AI build-out boom, which has lifted profits for a wide swath of companies and boosted economic growth. Investors were watching developments with CoreWeave, an AI cloud company with about $50 billion in debt. This week, its shares tumbled.
In other recent signs of caution, strategists at Deutsche Bank and RBC Capital Markets separately pulled back on their recommendations of the tech sector. On October 9, Deutsche Bank strategists said the rotation into tech had "run far and the risk-reward no longer looks favorable in the near term."
Despite the swoon in heavyweight tech and AI stocks, the S&P 500 remained down only about 1 per cent from its record high set this month. Other sectors, which lagged as tech soared in recent weeks, were now picking up the slack.
"This is very much an on-off switch type of market," Melson said. "When AI is working, it sucks all the oxygen out of the room for the rest of the sectors."
META KICKS OFF HYPERSCALER RESULTS
US reporting season heats up next week, with investors counting on robust performance. S&P 500 companies are expected to have increased earnings by more than 30 per cent in the third quarter, according to LSEG IBES.
Massive outlays on AI data centers and infrastructure underpin the profit jump. Meta is one of five AI hyperscalers that combined are expected to increase their capital spending to about $1.2 trillion next year, according to Goldman Sachs. Investors are eager for signs the companies can show returns on the investments, which would build confidence that the spending is sustainable.
"One of the most important takeaways of earnings season is whether or not the profitability of the hyperscalers can grow faster than the pace of their capex," said Kevin Shea, senior equity analyst at BNY Wealth.
Meta, whose market capitalization was about $1.9 trillion, has seen its shares climb in recent weeks as it launched its Muse AI assistant.
"With the cost of capital going up, this capex blowout is going to become more expensive, which raises the bar for returns," said Chuck Carlson, chief executive officer at Horizon Investment Services. "Meta is going to be the first up to try to provide some color around that question."
SEMIS, TESLA, NETFLIX ALSO ON TAP
Chip companies have been among the biggest beneficiaries of the capital spending boom, but the stocks have cooled off. The Philadelphia SE Semiconductor index has slumped 8 per cent this month, although it remained up more than 60 per cent on the year, compared to a 13 per cent year-to-date gain for the S&P 500.
Investors will look to Wednesday's reports from Lam Research and Texas Instruments for broader indications of demand in the semiconductor industry. Both companies' share prices are up some 60 per cent in 2026.
Elsewhere, investors will focus on results from Elon Musk's Tesla, another signature stock of the tech bull market. Streaming giant Netflix, consumer products company Procter & Gamble and engine maker GE Aerospace are among other high-profile reports in the coming week.
The rise in Treasury yields and prospects for further rate hikes from the Federal Reserve also remain front-burner issues for stock investors. Hot inflation data this week boosted bets on another rate increase at the Fed's meeting at the end of October. Futures pricing suggested most investors still expect the US central bank to wait until its meeting in December to raise rates for a second time this year.
"Another strong earnings season should help equities withstand moderately higher rates," analysts at UBS Global Wealth Management said in a note on Thursday.
