Tech Drags S&P 500, Nasdaq as Iran Tensions Mount - Monday, August 24, 2026

US stock markets experienced a mixed trading day on Monday, August 24, 2026, as technology stocks faced downward pressure while investors weighed geopolitical developments and anticipated key economic data and earnings reports later in the week.

Market Wrap

The S&P 500 declined, closing at 7,652.86 with a decrease of 0.28%. The Nasdaq Composite also fell, pressured by its heavy technology weighting. The Dow Jones Industrial Average, however, advanced, finishing at 53,417.16, an increase of 0.26%. This contrasted with a Reuters source that reported the Dow up 0.28%, S&P down 0.18%, and Nasdaq down 0.38% earlier in the day. The Russell 2000, a small-cap index, declined by 0.67% to 2,997.64. The CBOE Volatility Index (VIX) rose by 4.30% to 15.78, indicating an increase in market uncertainty.

What Drove It

Several factors influenced market performance on Monday:

1. Geopolitical Tensions: A primary driver was the escalating situation with Iran. Treasury Secretary Scott Bessent had threatened an "economic D-day" against Iran and later outlined plans for a stepped-up economic pressure campaign at a press conference. Investors awaited details of the threatened U.S. sanctions, contributing to market caution.
2. Technology Sector Weakness: The technology sector, particularly chip stocks, experienced pressure throughout the day. This weakness contributed significantly to the declines in the S&P 500 and Nasdaq. Investors were noted to be on edge ahead of Nvidia's upcoming earnings report, which is closely watched for fresh insights into artificial intelligence (AI) sentiment.
3. Anticipation of Key Data and Earnings: Markets were looking ahead to Nvidia's earnings and a crucial inflation report scheduled for later in the week. These upcoming events encouraged some investors to adopt a cautious stance, leading to repositioning, especially in tech.
4. Treasury Outlook: There was speculation that the Treasury could potentially tap its General Account to fund bond buybacks, a move that could affect bond market dynamics.

Sector Highlights

The market's performance indicated a divergence among sectors:

• Technology: This sector was a clear laggard, weighing down the S&P 500 and Nasdaq. Chip stocks, in particular, were under pressure.
• Financials: The KBW Nasdaq Bank Index advanced, rising by 0.66% to 187.18, suggesting relative strength in the banking sector.
• Other Sectors: While specific sector performance data beyond tech and financials was not detailed, the mixed performance of the major indices suggests a rotation or varied impact across different market segments.

Precious Metals & Commodities

• Oil: Crude oil prices maintained declines throughout the day. West Texas Intermediate (WTI) crude oil was at $85.24, down 2.09%. Brent crude futures declined by 2.56% to $91.97. This retreat in oil prices was seen as offering some relief to bond yields, coinciding with Bessent's outlining of the plan to squeeze Iran.
• Gold: Spot gold advanced, closing at $4,693.70, up 0.28%. This movement could reflect safe-haven demand amidst geopolitical uncertainties.
• US Dollar Index (DXY): The Dollar Index rose by 0.17% to 95.48.
• US 10-Year Treasury Yield: The yield on the U.S. 10-year Treasury note was at 4.708%. A dip in U.S. Treasury yields was noted as offsetting some weakness in global equities.

What to Watch Tomorrow

Investors will likely continue to monitor developments regarding U.S. sanctions against Iran. The upcoming Nvidia earnings report and a key inflation report later in the week are expected to be significant market movers, providing further direction for technology stocks and broader market sentiment regarding monetary policy. A speech by Fed official Warsh is also anticipated for potential guidance on monetary policy.

Bottom Line

Monday's trading session reflected investor caution driven by geopolitical tensions and specific sector weakness in technology ahead of critical earnings and economic data. Long-term investors should remain attentive to the broader macroeconomic picture and geopolitical developments while anticipating potential volatility around upcoming market-moving announcements.
