Investor sentiment in the artificial intelligence (AI) sector faces a critical moment this week as Meta prepares to release its third-quarter earnings after Wednesday’s market close in New York. The tech giant’s report will be closely watched ahead of earnings from Alphabet, Microsoft, and Amazon next week, amid growing concerns that AI-driven revenue growth may not meet market expectations.

Last week, major technology companies endured sharp market declines, with Nvidia losing more than $300 billion in market capitalization. The Philadelphia Semiconductor Sector dropped as much as 11 percent, while the Nasdaq 100 fell over 3 percent. These declines have stirred anxiety among investors about the sustainability of the AI-fueled rally that has buoyed the stock market in recent years.

Meta is expected to report revenue exceeding $63 billion for the quarter, but analysts anticipate a slowing growth rate. Adjusted operating income is forecasted at approximately $18.7 billion, a decline compared to both the previous quarter and the third quarter of 2025. Operating margins are also projected to shrink to below 30 percent, reflecting increased expenses related to AI investments. Venu Krishna, head of U.S. equity strategy at Barclays, emphasized the heightened scrutiny on earnings, noting that companies missing expectations recently faced significant market penalties, while those exceeding forecasts saw only modest gains. He said the sector is unlikely to replicate the robust returns of the past three years, particularly given the approaching U.S. midterm elections.

Across the Atlantic, economic data in the Eurozone continues to show resilience despite challenges including rising energy costs, trade tensions, and geopolitical uncertainty. Growth in the 21 countries using the euro has outperformed expectations so far this year, which has presented a conundrum for the European Central Bank (ECB). While stronger economic performance supports employment and public finances, it also risks keeping inflation, currently at 3.8 percent annually—almost double the ECB’s medium-term target of 2 percent—persistently elevated.

This week’s S&P Global Eurozone purchasing managers’ indices (PMIs), indicators of economic health, are anticipated to show slight declines but remain in expansion territory with readings around 52.5 for both manufacturing and services. Analysts at Pantheon Macroeconomics note that leading indicators suggest growth slowed in the third quarter, with GDP expected to rise by only 0.2 percent after 0.6 percent growth in the previous quarter. The ECB’s next policy meeting is scheduled for October 29, and while markets have priced in a quarter-point rate hike by year-end, the probability of an October increase remains low, at around 10 percent.

Meanwhile, in the United Kingdom, inflation data due this week is expected to show an acceleration in consumer price inflation to 3.4 percent in September from 3.1 percent in August, according to economists surveyed by Reuters. This figure surpasses the Bank of England’s forecast and remains well above its 2 percent target, intensifying pressure on policymakers to consider additional interest rate increases, potentially starting with a quarter-point rise in November.

Rob Wood, an economist at Pantheon Macroeconomics, highlighted that much of the anticipated inflation acceleration stems from already observed increases in motor fuel prices. Several members of the Bank of England’s Monetary Policy Committee (MPC) have hinted that further tightening may be necessary, although opinions vary on the scale. Market expectations currently include four quarter-point rate hikes by the end of next year. Strong economic growth of 0.7 percent in the three months to August adds to arguments for tighter monetary policy, as noted by analysts.

Ahead of Chancellor John Healey’s Budget on October 28, public finance figures scheduled for release this week are expected to show borrowing higher than previously forecasted by the Office for Budget Responsibility. Sanda Horsfield, an economist at Investec, attributes this to rising debt interest payments. She also anticipates that inflation and private sector wage growth data will reinforce MPC members’ resolve to pursue further rate increases.
