Market Recap 8/31/26
Markets closed modestly lower on Monday, August 31, with the Nasdaq showing relative resilience after bouncing off session lows, thanks in large part to a strong move in Tesla. The major averages finished the month in the green despite a turbulent August marked by geopolitical flare-ups, sticky inflation concerns, and shifting rate expectations.
The Dow dropped about 0.7% to close near 53,197. The S&P 500 slipped roughly 0.4–0.45% to around 7,677. The Nasdaq Composite fell about 0.37% to approximately 26,305 after trading as low as ~26,250. Breadth was negative, with decliners outpacing advancers, but the Nasdaq’s bounce and Tesla’s outperformance limited the damage compared with the broader tape.
What drove the session
Weekend military exchanges between the U.S. and Iran—the first acknowledged U.S. strike on Iranian soil in weeks, targeting rocket launchers near the Strait of Hormuz, followed by Iranian retaliation—sent oil prices higher (Brent climbed back above $90). Energy was the only S&P 500 sector in the green. Higher energy costs added to inflation worries already amplified by Fed Chair Kevin Warsh’s hawkish Jackson Hole remarks last Friday, which lifted September rate-hike odds.
Tesla rose around 5% and was a key stabilizer for the Nasdaq, offsetting weakness in names like Alphabet (down more than 2%). Most other mega-cap tech names finished mixed to lower. The session illustrated the market’s split personality: geopolitics and rates pressured cyclicals and rate-sensitive areas, while select growth/AI-adjacent names found buyers on dips.
August still ended positively. The Nasdaq gained roughly 3.5% for the month, the S&P 500 about 2.4%, and the Dow around 1.4% (its fifth straight monthly advance). Tech did much of the heavy lifting even as oil stayed elevated and yields remained high.
What to watch Tuesday, September 1
Focus shifts to data and earnings as the new month begins:
10:00 a.m. ET: ISM Manufacturing PMI for August, JOLTS job openings for July, and Construction Spending for July. These will be parsed for signs of cooling labor demand or lingering price pressures that could influence September FOMC pricing.
Earnings after the close: Dell Technologies, Palo Alto Networks, and MongoDB are among the notable reports. Dell’s AI-server commentary and Palo Alto’s cybersecurity outlook will get extra attention after recent strength in those themes.
Geopolitical headlines and oil remain live variables. Any further escalation (or de-escalation) in the Middle East could quickly move energy stocks and inflation expectations.
Watch Treasury yields and the dollar for follow-through from Friday’s hawkish repricing.
The calendar is reasonably active but not packed with blockbuster data until Friday’s August employment report (BIG FOR RATES). Positioning into month-end and the start of September often brings some volatility, so dips in quality names or continued Tesla/AI leadership could set the tone early in the week. Stay tuned for how the ISM reading lands against still-elevated rate-hike odds.
