The U.S. Stock Market is Closed for Labour Day on Monday, September 1, 2025

The U.S. stock market is closed for Labour Day on Monday, September 1, 2025, but investors are anxiously preparing for a dramatic post-holiday trading session as the S&P 500, Dow Jones, and Nasdaq teeter on pivotal support and resistance levels. September has a notorious reputation on Wall Street for volatility and underperformance—but could this be the year historic trends break, or is the market bracing for a steep correction?

The Calm Before a Potential Storm

While August ended with the S&P 500 touching record highs near 6,501 and the Dow Jones at 45,636, these indices now face formidable resistance and fading momentum. Historically, September leads to average declines for the S&P 500 and Dow, with only 44.9% and 42.2% of the time posting positive returns since their inceptions. With critical economic indicators—including the jobs report, inflation updates, and the Federal Reserve’s rate decision—set to hit over the next two weeks, what happens next could spark either relief rallies or sharp sell-offs.

S&P 500, DJIA, Nasdaq: Technical Outlook

The S&P 500’s struggle to decisively break above the 6,500 resistance raises concern of a short-term top, with technical analysts watching 6,470–6,480 as the critical bullish trigger, and 6,440–6,450 as must-hold support. A failed breakout could see the index retreat to 6,375 or even 6,200 in a sharper downturn. Meanwhile, the Dow and Nasdaq have mirrored this pattern, buoyed by tech’s stellar run and AI optimism, yet increasingly weighed by stretched valuations and faltering mega-cap earnings.

What Investors Should Watch

• Federal Reserve Policy: A widely-expected rate cut may come at September’s meeting, but the tone—dovish or hawkish—will be swayed by incoming jobs and inflation data.
• Jobs Report: After revisions and high-profile dismissals at the Bureau of Labor Statistics, any surprise in employment numbers could jolt volatility and trading flows.
• Market Volatility: With the VIX at historically low levels, the lull could be “the calm before the storm,” a precarious setup as institutional traders return from summer holidays.
• Tech and AI Stocks: Recent weakness in AI leaders like Nvidia has pulled the Nasdaq lower, signaling potential leadership rotation or larger market corrections ahead.

Top Stocks to Watch: In-Depth Analysis

Nvidia (NVDA)

Nvidia, the AI hardware behemoth, led the market for months but dropped 3.3% in the latest session as investors fretted over AI margin compression and high expectations. A decisive break below its 50-day moving average might trigger further institutional selling, but ultra-strong earnings and moat in AI could foster swift rebounds on any good news.

Tesla (TSLA)

Tesla’s recent -2.7% slide came amid renewed concerns about global EV demand and margin pressures. Short-term, the $245–$250 zone is vital support for any bullish reversal, while further downside could accelerate sector rotation.

Apple (AAPL) and Big Tech

Apple slid -2.1%, with both technical (overbought conditions) and macro risks (Chinese demand, antitrust scrutiny) weighing on sentiment. Expect choppy price action as traders seek clarity on holiday season demand.

Constellation Energy (CEG)

With a leadership spike of over +4%, Constellation Energy benefits from surging demand for data center power, a secular play in the green energy and AI infrastructure space. Continued upside could unfold if institutional demand persists.

Pfizer, UnitedHealth, Merck

Defensive sectors like healthcare staged strong gains. Amid macro uncertainty, these stocks are attractively positioned for capital rotation as investors seek stability over hyper-growth.
