Stocks declined last week as investors weighed growing concerns about artificial intelligence disruption alongside a warmer-than-expected wholesale inflation report. While tech stocks briefly rebounded midweek, inflation data and renewed uncertainty pressured markets into the close.

Key Takeaways

AI disruption concerns broadened beyond tech and weighed on sentiment
A midweek relief rally faded as inflation pressures resurfaced
Wholesale inflation came in hotter than expected
International stocks outperformed U.S. markets

YCharts.com, February 28, 2026. Weekly performance is measured from Monday, February 23, to Friday, February 27.

Market Performance Snapshot

The S&P 500 Index declined 0.44 percent for the week, while the Nasdaq Composite fell 0.95 percent, reflecting pressure in growth-oriented sectors. The Dow Jones Industrial Average dropped 1.27 percent, underperforming both the S&P 500 and Nasdaq despite still leading year to date.

In contrast, developed international stocks gained 1.22 percent. The divergence highlighted continued dispersion beneath the surface, with global equities showing relative resilience even as U.S. indexes faced inflation and sector-specific headwinds.

AI Disruption Fears Spread

Markets opened under pressure as a widely circulated research report suggested artificial intelligence could influence a broader set of industries and potentially affect the unemployment rate. That narrative extended beyond traditional technology companies and contributed to early-week volatility.

Stocks rebounded over the next two sessions as investors stepped into what appeared to be an oversold AI trade. Software, cybersecurity, and semiconductor-related names participated in the relief rally, helped by optimism surrounding a prominent chipmaker’s upcoming earnings report.

However, the rally lost momentum late in the week. The Dow Industrials weakened noticeably over the final two sessions, underperforming on Friday and for the week, even though it remains ahead of other major averages year to date.

Wholesale Inflation Reignites Rate Concerns

Friday’s shutdown-delayed Producer Price Index report showed wholesale inflation rose 0.5 percent in January, above the 0.3 percent economists had expected.

Because PPI measures input costs for businesses, stronger readings often raise concerns that higher costs could eventually be passed along to consumers. Inflation data that remains above the Federal Reserve’s 2 percent target can complicate expectations around future rate policy.

The hotter reading added pressure to equities into the weekend, reinforcing the view that inflation remains a central market driver.
