Wall Street closed the week on a weak note, with technology and semiconductor stocks once again at the center of the market’s troubles.
While investors received some encouraging news on inflation, it was not enough to offset growing concerns surrounding chipmakers, AI valuations, and the broader outlook for the stock market.
The result was another difficult week for US equities, especially for technology-heavy indexes.
A Tough Week for Major Indexes
The S&P 500 slipped 0.1% on Friday, marking its biggest weekly decline since early June. More importantly for many technical traders, the benchmark index closed below its 50-day moving average for the first time since April. This level is often viewed as an important indicator of market momentum.
The Nasdaq 100, which has been heavily driven by large technology companies and AI-related stocks, fell 1.1% on Friday and finished the week down nearly 4%.
Meanwhile, the Dow Jones Industrial Average also edged lower by 0.1%.
Throughout the week, markets attempted several rebounds, but each rally quickly faded.
According to Steve Sosnick, chief strategist at Interactive Brokers, investors repeatedly tried to push stocks higher, only to see those gains disappear almost immediately. That pattern reflects growing uncertainty and a lack of conviction among buyers.
Chip Stocks Continue to Drag Markets Lower
Semiconductor companies were among the biggest losers during the week.
One notable decline came from ON Semiconductor, whose shares dropped sharply after the company announced an all-stock acquisition of Synaptics. The deal prompted a downgrade from TD Securities, adding further pressure on the stock.
The broader semiconductor sector has been under stress globally, not just in the United States.
Recent declines in Asian markets have spilled over into US trading, creating fresh doubts about whether investors have become overly optimistic about the future earnings potential of AI-related companies.
Inflation Data Offers Some Relief
There was at least one positive development.
A survey from the University of Michigan showed that long-term inflation expectations eased slightly. Respondents now expect inflation to average 3.3% over the next five to ten years, down from the previous estimate of 3.4%.
Consumer sentiment also improved modestly, although it remains historically weak.
Lower inflation expectations are generally viewed positively because they reduce pressure on the Federal Reserve to raise interest rates aggressively.
Markets briefly turned positive following the data release, but optimism faded as concerns over technology valuations resurfaced.
Is the AI Trade Losing Momentum?
The biggest conversation dominating markets right now is whether AI-related stocks have become too expensive.
Concerns intensified after two prominent Chinese hedge funds warned that the AI sector may be experiencing a speculative bubble that could eventually burst.
Those comments added to existing worries among investors who have already watched many high-profile AI and technology stocks struggle to regain previous highs.
Additional uncertainty emerged after reports suggested that OpenAI may postpone its planned initial public offering until 2027. The news weighed on SoftBank shares in Japan and further dampened enthusiasm surrounding the AI investment theme.
Some market professionals believe investors are beginning to question how long they are willing to wait for major AI investments to translate into meaningful profits.
Cameron Dawson, chief investment officer at Newedge Wealth, noted that investors are increasingly asking whether the market has enough patience to wait for hyperscalers to generate returns from their enormous AI spending.
Investors Pull Money Out of US Stocks
Investor sentiment appears to be weakening.
According to Bank of America data, investors withdrew approximately $8.5 billion from US equities during the latest reporting period. It was the first net outflow from US stock funds in roughly three months.
That shift suggests some investors are becoming more cautious after the strong rally earlier this year.
Richard Reyle, chief investment officer at Questar Capital Partners, argued that investors should be careful about chasing big technology and AI stocks at current valuations, noting that market leadership has started to narrow and momentum has weakened.
Falling Oil Prices Could Help Inflation
Away from equities, oil prices continued to decline.
Crude extended recent losses as shipping traffic through the Strait of Hormuz remained largely uninterrupted despite geopolitical tensions in the region.
Lower energy prices could provide additional support for inflation to cool further in the coming months.
Brian Jacobsen, chief economic strategist at Annex Wealth Management, believes that with energy prices retreating, headline inflation may finally have room to move lower, although broader price pressures have not disappeared entirely.
What Investors Should Watch Next
Several key themes are likely to drive markets in the coming weeks:
Investors will closely monitor:
- Whether semiconductor stocks can stabilize after the recent selloff.
- Upcoming corporate earnings from major technology and AI companies.
- Signs that massive AI spending is beginning to generate meaningful returns.
- Inflation data and the Federal Reserve’s next policy decisions.
- Fund flow trends to determine whether investors continue pulling money out of equities.
For now, the market appears to be entering a period where valuations matter more than narratives. The excitement surrounding AI remains strong, but investors are increasingly demanding evidence that today’s enormous investments will eventually produce substantial profits.
The coming earnings season may provide some of the answers Wall Street is looking for.
