US stock: S&P 500 ends lower as investors weigh data, Middle East tensions

Introduction

U.S. equities retreated on Friday, pulling the S&P 500 down from its previous record high as investors processed softer-than-expected retail figures and evaluated escalating geopolitical friction in the Middle East. Major market benchmarks finished the session in negative territory, led downward by pullbacks in key semiconductor equities and cautious sentiment surrounding lofty valuations.

The S&P 500 slipped 13.41 points, or 0.17 percent, to close the trading day at 7,785.58. Simultaneously, the tech-heavy Nasdaq Composite dropped 73.86 points, or 0.28 percent, ending at 26,729.16, while the Dow Jones Industrial Average retreated 108.53 points, or 0.20 percent, to settle at 53,732.53.

What Happened

Market momentum hit a wall on Friday as robust expectations collided with corporate earnings reports and fresh economic readings. Applied Materials served as a primary weight on the S&P 500 after the chip equipment manufacturer delivered an upbeat quarterly forecast that ultimately failed to satisfy Wall Street. Despite seeing its shares double throughout 2026 amid soaring demand for artificial intelligence data center infrastructure, the company experienced a sell-off because market expectations had climbed too high.

This dynamic rippled across the broader technology sector, dragging down fellow chipmakers such as Broadcom and Intel. According to Thomas Martin, senior portfolio manager at GLOBALT Investments in Atlanta, market drivers remain heavily concentrated around various facets of artificial intelligence, leaving firms like Applied Materials vulnerable to profit-taking when guidance fails to exceed already elevated benchmarks.

Simultaneously, international anxieties intensified as maritime transit through the Strait of Hormuz neared a complete standstill. The disruption followed fresh attacks on two vessels in the corridor and an announcement from the United States indicating it could sustain a naval blockade of Iran indefinitely. These geopolitical headwinds deepened market pessimism following statements from a senior Iranian official earlier in the week confirming a lack of progress in negotiations to advance a June agreement aimed at concluding the war.

Background

The recent pullback occurs against a backdrop of phenomenal growth tied to artificial intelligence technologies over the past few years. Driven largely by heavyweights such as Amazon and Microsoft, aggregate earnings across S&P 500 companies surged by 52 percent in the second quarter, according to data from LSEG.

Even with the S&P 500 hovering just below record territory, the index valuation sits at approximately 20 times expected earnings. This valuation level represents a moderate increase from roughly 19 at the conclusion of July, though it remains below the multiple of 22 recorded at the beginning of 2026.

Timeline

Date / Period Event
June An agreement was established aiming to end the war, which later stalled
Wednesday A senior Iranian source reported no progress in building upon the June agreement
Late Thursday President Donald Trump announced planned tariffs on imported drones and components; Reuters reported Silver Lake talks regarding Workday
Friday S&P 500 closed lower; retail sales and consumer sentiment data released; maritime attacks occurred in the Strait of Hormuz
August 18 Effective date for Reddit's addition to the S&P 500 index

Key Details

Economic indicators released on Friday offered mixed signals regarding the health of domestic consumer spending and sentiment. The Commerce Department's Census Bureau reported that July retail sales came in weaker than anticipated, following an unrevised 0.2 percent gain in May. Complemented by this data, the University of Michigan preliminary consumer sentiment survey registered at 51 for August, falling short of the 54.5 consensus expectations compiled by Reuters economists.

Despite lingering inflation worries linked to rising oil prices, current economic figures have solidified expectations that the Federal Reserve will maintain its benchmark interest rate during the upcoming September meeting. CME FedWatch tools indicate a 67 percent probability that the central bank will leave rates untouched, alongside a 33 percent likelihood of a rate hike.

Corporate developments also generated isolated sector movements during the session. Reddit shares surged following the announcement that the social media platform will officially join the S&P 500 index on August 18. Meanwhile, drone manufacturers Red Cat and Unusual Machines experienced notable share price jumps after President Donald Trump stated late Thursday that he intends to impose tariffs on imported drones and their component parts. Conversely, software provider Workday dipped following a sharp 18 percent rally on Thursday triggered by a Reuters report detailing buyout discussions with private equity firm Silver Lake.

Impact

Energy equities provided a counterweight to the broader market decline, with the S&P 500 energy index rallying in tandem with rising crude oil prices. While higher energy costs continue to fuel broader inflation concerns among economists and investors, they directly bolstered sector performance on Friday.

Geopolitical friction in the Middle East and ongoing supply route blockages threaten to maintain upward pressure on global energy markets. Meanwhile, the broader tech sector faces heightened scrutiny as market participants re-evaluate high valuations tied to artificial intelligence infrastructure growth.

What Happens Next

Market participants are closely monitoring upcoming macroeconomic reports and central bank communications ahead of the Federal Reserve policy meeting in September. Traders will continue tracking CME FedWatch probabilities to gauge shifts in monetary policy expectations. Additionally, investors await the formal inclusion of Reddit into the S&P 500 index scheduled for August 18.
