Ações dos EUA mudam de direção com suavidade no mercado de trabalho, em meio a preocupações com vendas internas

Labor Market Cooling and Monetary Policy Shifts

The US labor market delivered a significant shock in July, with nonfarm payrolls unexpectedly falling by 23,000 [1, 2, 9]. This figure missed market consensus estimates, which had anticipated a gain of between 80,000 and 83,000 jobs [1, 7]. The data also revealed a slowdown in wage growth, as average hourly earnings rose only 0.1% month-over-month and 3.2% year-over-year, marking the slowest growth rate in over five years [2]. Furthermore, significant downward revisions were applied to previous months, with May and June combined being revised down by 103,000 jobs [2].

This "anti-inflation surprise" has fundamentally altered the outlook for US monetary policy [2]. The weakening employment data and slowing wage growth have dissipated fears of aggressive interest rate hikes, providing the Federal Reserve with more room to delay increases [2, 19]. Consequently, the perceived probability of a Federal Reserve rate hike in September fell from 58% to a range between 40% and 44% [1, 16, 19].

The market reaction to this shift was immediate. US stocks rose as investors anticipated easier monetary policy [1, 19]. The S&P 500 saw gains between 0.25% and 0.62% [1], while the Nasdaq composite rose between 1% and 1.3% [1]. The Dow Jones Industrial Average also recorded a 0.2% increase [7]. This rally was supported by a decline in Treasury yields, with the 10-year yield falling to a range of 4.62%–4.65% [1, 7] and the 2-year yield dropping approximately 8 basis points to a range of 4.16–4.17% [1].

Sector Divergence and Thematic Momentum

While the broader market reacted to macro shifts, specific sectors showed distinct directional trends. Technology and semiconductor-linked sectors appeared particularly supported by the prospect of a more dovish Fed [1]. Within this space, specific gains were noted in Nvidia, which rose 1.6%, and Broadcom, which rose 1% [7].

In contrast to the broader tech-driven optimism, certain energy and infrastructure themes showed robust independent momentum. The nuclear and large-scale construction segments appear to be benefiting from the energy transition:

• Fluor Corporation reached a new 52-week high of $55.30 following quarterly revenue of $4.33 billion, an 8.8% year-over-year increase [3].
• BWX Technologies, Inc. reported second-quarter revenue growth of approximately 18% year-over-year, accompanied by a 40% increase in its backlog [3].
• PN Smart Energy Limited announced a $5.0 million registered direct offering of securities [3].

The travel and aviation sectors, however, present a more sideways outlook characterized by operational friction. While online travel providers like Expedia Group are maintaining capital returns through dividends, the aviation industry is facing headwinds from intensified ICE enforcement at airports and recent airspace safety concerns involving a Marine One helicopter and an Envoy Air flight in Washington D.C. [6].

Signals of Market Fragility

Despite record highs in the Dow Jones and S&P 500, the data suggests significant underlying fragility in US equities [6]. A primary concern stems from large-scale insider selling that occurred on August 3, 2026. On that single day, insiders sold $347 million of Amazon Com Inc stock and $157 million of Chevron Corp stock [13, 4]. The sale of Chevron stock contributed to a 1.9% single-day decline, with the stock down 3.6% in total since that transaction [13].

This insider liquidation serves as a potential counter-signal to broader market optimism, suggesting cautious positioning among major institutional actors [6]. Furthermore, there are growing warnings regarding potential financial bubbles, specifically concerning excessive valuations within the artificial intelligence sector [6].

Geopolitical tensions also remain a persistent headwind. Stability in the Middle East, particularly regarding the Strait of Hormuz and negotiations between Iran and Oman, remains a critical variable for energy markets [6]. Additionally, ongoing trade tensions between the US and China continue to introduce volatility into the macro environment [6].

What to watch

• The Federal Reserve's upcoming policy stance and its reaction to the recent employment and inflation signals.
• Geopolitical developments in the Middle East, specifically the finalization of agreements between Iran and Oman regarding ship control and service fees in the Strait of Hormuz.
• Upcoming corporate earnings, including Quantum Computing Inc. (QUBT) on Monday, August 10.
• The August 27th record date for Expedia's dividend and any NTSB or FAA findings regarding the Washington airspace incident.
