The Stock Market Could Make Big Moves This Week Following Critical News on Nvidia, Interest Rates, and Inflation

The S&P 500's recent rebound faces near-term headwinds as investors await Nvidia's Q1 earnings (analysts concerned about export restrictions and gross margins), the Federal Reserve's meeting minutes (scrutiny of tariff concerns and stagflation risks), and Commerce Department data on PCE inflation and consumer spending (potential impact of tariffs). Market reactions will hinge on whether these reports confirm or alleviate concerns about tariffs impacting prices, economic growth, and Fed policy.

Analysis

The S&P 500 has demonstrated an 18% rebound since early April, a period initiated by President Trump's "Liberation Day" tariff announcements, with a recent surge on May 27 attributed to easing EU-US trade tensions. However, the market faces significant near-term catalysts that could introduce volatility. Nvidia's first-quarter fiscal 2026 earnings, due May 28, are a focal point; while the company guided for 65% sales growth and 49% non-GAAP net income growth, analyst estimates have been revised downwards, with the Wall Street consensus implying a 44% earnings increase to $0.88 per diluted share, amid concerns over chip export restrictions and tariffs. Critical attention will be on Nvidia's gross margin, which narrowed to 73.5% in Q4 and is guided to contract further to 71% in Q1 due to Blackwell GPU ramp-up costs, though a recovery to the mid-70% range is anticipated late in the fiscal year; options markets are pricing in an approximate 6% post-earnings stock movement. Concurrently, the Federal Reserve will release its May meeting minutes on May 28, which will be scrutinized for commentary on tariff impacts and stagflation risks, particularly after March minutes highlighted concerns about rising inflation and slowing employment. Finally, the Commerce Department's April 2025 Personal Consumption Expenditure (PCE) inflation and consumer spending data, due May 30, will be pivotal. The consensus projects PCE inflation at 2.2% year-over-year and consumer spending growth at 0.2% month-over-month; deviations, especially higher inflation or lower spending, could signal adverse tariff effects, potentially pressuring equities. The overall sentiment is cautious, reflecting these impending data points and their potential to confirm or alleviate concerns about tariffs impacting corporate performance, economic growth, and Federal Reserve policy.

Key Decisions for Investors

• Investors should closely monitor Nvidia's upcoming earnings report on May 28, paying particular attention to gross margin trends and management's outlook concerning export restrictions and tariffs, while being prepared for potential stock volatility as indicated by options market pricing.
• Scrutinize the Federal Reserve's May meeting minutes, also released on May 28, for insights into officials' assessment of tariff impacts on inflation and economic growth, and any evolving views on stagflation risks.
• Evaluate the April PCE inflation and consumer spending data due May 30, as figures significantly deviating from the consensus (2.2% YoY for PCE, 0.2% MoM for spending) could trigger market repricing based on perceived tariff effects.
• Given the confluence of potentially impactful economic releases and corporate earnings centered around tariff concerns, consider maintaining a cautious stance and assessing portfolio sensitivity to trade policy and inflationary pressures until greater clarity emerges.
