Wall Street ends lower as chip weakness offsets solid earnings, economic data

The major U.S. Stock indexes ended lower on Thursday, July 16, 2026, as a steep decline in semiconductor stocks overwhelmed positive economic indicators and the start of the second-quarter earnings season. The technology sector fell 1.8%, with semiconductor stocks dropping 4.3%, weighing heavily on the broader market.

The Nasdaq Composite lost 387.28 points, or 1.47%, to finish at 25,881.95. The S&P 500 declined 38.63 points, or 0.51%, to 7,533.77, while the Dow Jones Industrial Average fell 105.32 points, or 0.20%, to 52,553.32.

The volatility in chip stocks has increasingly dictated index movements. Paul Nolte, senior wealth advisor and market strategist at Murphy & Sylvest, noted that chip weight in the S&P 500 has grown from 8% three or four years ago to over 20% currently.

Chip Sector Volatility

Despite a 77% jump in quarterly profit from bellwether TSMC, U.S.-listed shares of the chipmaker fell 2.3%. Memory-chip manufacturers saw the steepest losses, with Intel, Seagate Technology, Western Digital, and SanDisk declining between 5.8% and 12.6%.

Tim Ghriskey, senior portfolio strategist at Ingalls & Snyder, described the extreme swings in portfolio values as disconcerting for average investors, though he noted that non-tech sectors continued to perform well.

Mixed Economic and Earnings Data

Markets faced a backdrop of contradictory data. Positive indicators included a drop in jobless claims, solid core retail sales, and surging manufacturing activity in the Northeast. However, the housing sector struggled, with homebuilder sentiment souring and a larger-than-expected drop in pending home sales due to high borrowing costs.

The start of the second-quarter earnings season showed mixed results for major companies:

• UnitedHealth Group: Gained 1.2% after beating earnings estimates and raising its 2026 forecast.
• GE Aerospace: Fell 4.1% despite lifting its 2026 profit forecast.
• United Airlines: Dropped 1.8% as rising oil prices impacted forward guidance.

Analysts have set high expectations for the season, with LSEG data indicating aggregate year-on-year earnings growth of 24.8% for S&P 500 companies and a projected 65.5% jump for technology earnings.

Monetary Policy and Inflation Concerns

Federal Reserve officials signaled a cautious approach to inflation. Kansas City Fed President Jeff Schmid described inflation as concerning and broad-based, warning that price pressures remain elevated above the target. He cautioned against viewing recent softer data as a sustained trend.

Dallas Fed President Lorie Logan called for modestly higher interest rates, arguing that current policy is not sufficiently restraining the economy. She noted that while wages are not currently a primary source of pressure, there are early signs of faster wage increases among some Texas businesses.

Geopolitical Tensions and Energy

Sentiment remained cautious as the U.S. And Iran extended a barrage of airstrikes, prolonging a week-long escalation. While Iran released a U.S. Citizen, suggesting a possible path to avoid all-out war, oil markets remain volatile. Brent and WTI prices slipped about 0.2% after earlier gains of more than 1%.

Supply concerns have been intensified by Iran asking Yemen's Houthi movement to prepare to close the Red Sea route. U.S. Refining margins have reached record levels, with the benchmark 3-2-1 crack spread hitting around $70 per barrel due to tight supply and low inventories.

Corporate and Global Developments

In other business news, Apollo Global Management Inc. Plans to deploy up to $20 billion in Mexico for private credit deals involving energy and infrastructure. Meanwhile, Google delayed the launch of its Gemini 3.5 Pro AI model to improve coding performance, amid internal concerns regarding bureaucracy and competition from Anthropic and OpenAI.

Internationally, Brazil announced it will challenge a 25% tariff imposed by Donald Trump at the World Trade Organization, with President Luiz Inácio Lula da Silva rejecting claims of unfair trade.

In the hedge fund space, Paloma Partners is halving its portfolio manager teams to about 10. Founder Donald Sussman is pivoting toward high-conviction strategies and eliminating management fees for at least two years following a drop in assets from about $4 billion in 2023 to roughly $1.1 billion last year.

Investors now look toward the Federal Reserve's July meeting, with markets pricing in the possibility of a September rate hike.
