Stock market today: Dow, Nasdaq, S&P 500 rise as investors cheer Nvidia earnings, weigh tariff legal whiplash

US stocks closed higher Thursday, driven by Nvidia's better-than-expected earnings despite a warning about an $8 billion revenue hit due to China export restrictions; NVDA shares rallied over 3%. A federal appeals court temporarily upheld Trump's tariffs after a lower court ruling against them, adding to market uncertainty, while Best Buy cut its full-year guidance citing tariff-related economic concerns. Investors are closely watching Costco's after-hours report amid ongoing trade policy debates.

Analysis

US equity markets saw modest gains, with the S&P 500 and Nasdaq Composite closing up approximately 0.4% each and the Dow Jones Industrial Average climbing around 0.3%, influenced by strong technology sector performance amidst persistent trade policy uncertainty. Nvidia's (NVDA) stock rallied 3.25% after its first-quarter revenue topped estimates, and other tech giants like Tesla (TSLA), which rose 2% on positive news, also contributed to gains. However, Nvidia also warned of an $8 billion sales impact in the second quarter due to US restrictions on exports to China, highlighting specific vulnerabilities within the tech sector. Concurrently, market sentiment was tempered by a federal appeals court decision allowing President Trump's tariffs to temporarily remain in effect, reversing a lower court's block and heightening trade-related anxieties. This uncertainty directly impacted the retail sector, evidenced by Best Buy (BBY) cutting its full-year guidance due to tariff concerns, leading to a stock decline. Adding to a cautious economic outlook, initial filings for unemployment aid jumped more than expected, and the Commerce Department reported a 0.2% annualized GDP contraction for the first quarter.

Key Decisions for Investors

• Investors should closely monitor ongoing trade policy developments and legal challenges concerning tariffs, as these factors are creating significant market uncertainty and directly impacting corporate earnings guidance, particularly in the retail sector.
• While Nvidia's strong Q1 earnings provide a positive signal for parts of the technology sector, its substantial Q2 revenue warning due to China export restrictions underscores the specific risks for companies with significant international exposure, warranting careful evaluation of individual company fundamentals within tech.
• Given Best Buy's guidance cut and the reported negative Q1 GDP growth, a cautious approach towards consumer discretionary stocks vulnerable to tariff impacts and a slowing economic environment may be prudent, especially when contrasted with the current strength in specific large-cap technology names.
• The divergence between robust earnings from certain technology companies, like Nvidia, and weakening broader economic indicators, such as rising unemployment claims, points towards a bifurcated market that necessitates careful sector and stock selection rather than broad market-based strategies.
