AI Worries Outweigh Strong Economic Data

AI Worries Outweigh Strong Economic Data

Key takeaways

  • AI concerns are overshadowing strong economic data: Stocks fell last week as investors questioned whether the artificial intelligence (AI) buildout is sustainable. The Nasdaq 100 dropped 4.91 percent for the week, including a 6.4 percent slide on Thursday that erased a record $2.3 trillion in market value. The S&P 500 finished the week down 2.68 percent.

  • A strong economy leaves the Fed in a tough spot: Payrolls rose 165,000 versus 70,000 expected, the unemployment rate fell to 4.1 percent, and the Institute for Supply Management (ISM) Manufacturing Index rose to 55.5. But the economy-weighted ISM Prices Index remains elevated at 73.2, and the odds of a December Fed rate hike fell to 77 percent on Friday from 90 percent on October 19, moving in step with the stock market.

  • Diversification is cushioning the blow: The Nasdaq 100 is down 13.56 percent from its October high, but the S&P 500 is off only 5.6 percent, and seven of its 11 sectors are still positive, led by defensive staples and health care. However, if AI concerns grow, the slowdown could spill into more parts of the market.

In a week that once again featured solid economic data, stocks faltered as investors continued to question the sustainability of the AI boom. This came in the context of the U.S. midterm elections, which saw the Democrats decisively take control of both the House and the Senate and win numerous gubernatorial races—even in traditionally Republican states. Stocks opened the post-election period with a sharp relief rally on Wednesday, albeit with AI-related names posting declines. That gave way to a broad rout on Thursday, when nearly every nook and cranny of the financial markets saw losses and the tech-heavy Nasdaq 100 fell 6.4 percent, wiping out a record $2.3 trillion in market value in a single day. Markets recovered some of those losses on Friday, but the S&P 500 still finished the week down 2.68 percent, led by losses in industrials (-2.83 percent), technology (-6.93 percent), and energy, which fell 11.93 percent on hopes that the U.S. and Iran could reach a deal.

The data released last week built on previous weeks and showed an economy that is still broadly pushing forward. The ISM Manufacturing Index rose to 55.5 from 54.5 (figures above 50 indicate growth), which, aside from a 55.6 reading in May, was the highest level since May 2022. Production also spiked to 59, the highest level since November 2021. The ISM Services Index remained in expansion even though it pulled back slightly to 54.5 from last month’s 54.9, leaving the economy-weighted ISM at 54.6, down from 54.9 and 55.3 in the previous two months but still at the highest levels since September 2022. The bad news is that the economy-weighted Prices Index remained at 73.2, down slightly from last month’s 74.3 but (aside from that September reading) still the highest level since June 2022. Indeed, data going back to 1997 shows only 7 percent of the 352 observations have been higher, and they have occurred in periods of heightened inflation.

The labor market report was equally strong and broad. Payrolls rose 165,000 versus the 70,000 expected, and the September number was revised higher to 60,000 from 29,000, part of a two-month revision that added 84,000. Private payrolls rose 159,000, with the previous month revised higher to 78,000 from 46,000, while manufacturing added 19,000 after a 13,000 gain. Hiring remained spread across multiple industries, with the one-month diffusion index holding above 50 for the 10th month in a row, while the three-month diffusion index rose to 60.4 from 58.6—the highest since June 2023. The unemployment rate fell to 4.1 percent from 4.2 percent.
