The stock market today finished mixed after an early relief rally lost momentum. The S&P 500 edged up less than 0.1%, the Dow gained 0.5%, and the Nasdaq Composite slipped 0.2% as a 5% drop in Nvidia weighed on technology shares.
The day's biggest move came outside equities. Brent crude fell 6.3% to $85.87 a barrel after the United States and Iran paused attacks and efforts resumed to restart negotiations. That eased the immediate energy-inflation threat, but the muted reaction in stocks and bonds showed that investors are not treating the geopolitical risk—or this week's Federal Reserve decision—as settled.
The markers
- S&P 500: 7,413.18, up 1.20 points, or less than 0.1%
- Dow Jones Industrial Average: 52,210.08, up 262.83 points, or 0.5%
- Nasdaq Composite: 24,932.08, down 43.74 points, or 0.2%
- Russell 2000: 2,948.03, up 18.04 points, or 0.6%
- Brent crude: $85.87, down 6.3%
- 10-year Treasury yield: about 4.65%, down from 4.69% Friday
Breadth was healthier than the flat headline suggested. Seven of the S&P 500's 11 sectors rose, while communication services and consumer staples gained roughly 1.5%. Energy fell about 2% and technology lost about 1%.
That split matters. Monday was not a broad retreat from risk. It was another rotation away from the most crowded technology exposure while smaller companies, financial stocks, defensives and communication-services names found support.
What moved markets today
The pause in U.S.-Iran attacks initially lifted equity futures and pushed crude sharply lower. Energy-sensitive travel stocks benefited from the prospect of lower fuel costs, while oil producers weakened. The relief faded as the session progressed because shipping through the Strait of Hormuz remained subdued and investors questioned how durable the diplomatic opening would be.
The bond market also delivered a cautious verdict. The 10-year Treasury yield fell to roughly 4.65%, but that was only a modest move after Brent's steep decline. Long-term yields remain elevated, and the 30-year Treasury has stayed above 5% for its longest stretch since 2007. Investors still see inflation pressure extending beyond a single day's oil move.
Technology supplied the other major cross-current. Nvidia fell 5% and Micron lost 2.3%, while Microsoft gained 1.9% and Apple rose 1.2%. Alphabet added 2.1%. The mixed performance inside megacap technology kept the index-level result subdued even though most S&P 500 stocks advanced.
Chinese memory-chip maker CXMT's blockbuster Shanghai debut added a competitive angle to the semiconductor selloff. At the same time, reports of increasingly large financing commitments around AI data centers reinforced concerns about circular funding, capital intensity and the eventual return on AI investment.
Why the oil decline was not enough
A sustained drop in energy prices would be constructive for consumers, corporate margins and inflation expectations. Monday's market action, however, distinguished between immediate relief and a durable change in trend.
Brent traded above $100 last week, and the conflict has not ended. New global tariffs remain another possible source of price pressure. With both geopolitical and trade risks active, one lower oil settlement does not give the Federal Reserve an all-clear signal.
That helps explain why the S&P 500 surrendered most of its early advance. The market received a favorable oil shock, but investors still face a highly uncertain Fed decision and earnings reports that could reset expectations for the largest technology companies.
Fed and Big Tech take center stage
The Federal Reserve announces its policy decision Wednesday. Futures pricing implied roughly a one-in-three chance of a quarter-point rate increase late Monday, making this one of the least predictable meetings in recent years. The central bank has kept rates steady this year while assessing higher inflation tied to energy and tariffs.
Thursday's personal consumption expenditures inflation report will then provide the Fed's preferred inflation measure. A hotter reading could revive upward pressure on Treasury yields even if oil remains below last week's peak.
Microsoft, Meta, Amazon and Apple also report this week. Investors will focus less on headline revenue growth and more on capital spending, margins, cash flow and evidence that AI investment can produce attractive returns. After recent punishment for rising spending plans, strong demand alone may no longer be enough.
What we're watching next
- The Federal Reserve's Wednesday rate decision and Chair Kevin Warsh's press conference
- Thursday's PCE inflation report
- AI capital-spending and cash-flow guidance from Microsoft, Meta, Amazon and Apple
- Whether Nvidia and the semiconductor index stabilize after another weak session
- Whether Brent holds below $90 or rebounds on renewed Middle East tension
- The 10-year Treasury yield near 4.65% and the 30-year yield above 5%
- July consumer confidence and earnings from Visa, Coca-Cola and Boeing on Tuesday
Bottom-line summary
- The S&P 500's flat close hid positive breadth and a continued rotation away from technology.
- Brent's 6.3% plunge reduced the immediate inflation threat, but bonds showed limited conviction that the relief will last.
- Nvidia's 5% drop kept AI financing, competition and return on investment at the center of the market debate.
- The Fed, PCE inflation and four megacap earnings reports now form the week's decisive test.
The practical takeaway is that falling oil helps, but it does not remove the market's two largest constraints: elevated long-term yields and rising scrutiny of AI spending. Monday's broader participation was constructive. A more durable risk-on signal would require that breadth to persist while Treasury yields ease and technology finds a floor.
