U.S. equities closed Thursday’s volatile session with divergent outcomes as sweeping new tariffs by the Trump administration took center stage, roiling global trade and amplifying uncertainty in world markets. Despite the mounting tensions, the technology-driven Nasdaq Composite surged nearly 0.4% to a record close, propelled by outsized gains in major tech stocks, most notably Apple and leading semiconductor firms. In contrast, the Dow Jones Industrial Average slumped 0.5%, pressured by negative earnings surprises and renewed doubts about the broader U.S. economy. The S&P 500 ended little changed as market participants weighed defensive versus growth sectors amid a rapidly shifting macroeconomic backdrop.

President Trump’s trade deadline arrived at 12:01 a.m. ET on Thursday, imposing duties ranging from 10% to 50% on imports from nearly 200 countries—an escalation that has driven the average effective U.S. tariff rate to a projected 18.6% according to the Yale Budget Lab, the highest since the 1930s. The move marks a radical reshaping of U.S. trade policy and draws contentious responses both domestically and from abroad as economists warn of possible inflationary impacts and pressure on global supply chains.

Technology Leads Amid Trade Turmoil

In spite of headwinds, the tech-heavy Nasdaq continued its record-breaking streak, driven by momentum in Big Tech and semiconductor stocks. Apple Inc. (AAPL) led the charge with its shares rising 3.17% after the company, alongside President Trump, announced a landmark $100 billion investment to ramp up U.S. operations. The plan includes onshoring key elements of iPhone and Apple Watch production to Kentucky, a move widely interpreted as a partial concession to counteract the new tariff regime. While some shareholders cautioned the investment was more “optics than impact,” markets responded bullishly to the company’s domestic manufacturing boost.

Semiconductor stocks also rallied after Trump indicated that companies shifting chip production to the U.S. could be exempted from the planned 100% semiconductor tariffs. Nvidia (NVDA) gained 0.7%, Broadcom (AVGO) rose 1.7%, and Micron (MU) increased 3.4%. The world’s leading chip foundry, TSMC, soared nearly 7% on news that its new Arizona facility would position the company for tariff exemptions. This dovetails with a wave of domestic investment announcements from U.S. chipmakers, including Nvidia’s recent $500 billion commitment to AI infrastructure in the United States and Micron’s $200 billion plan to bolster U.S. memory manufacturing capacity.

Tariffs Reshape Corporate Earnings and Global Supply Chains

Corporate America continued to digest the ramifications of the new trade landscape. In corporate earnings news, Toyota (TM) slashed its full-year profit guidance, warning of a $9.5 billion hit from U.S. tariffs. The auto giant is among a list of industry leaders—including Ford, GM, and various consumer goods firms—issuing similar warnings about the cost pressures and uncertainty posed by the new duties. The consumer sector, meanwhile, showed resilience, highlighted by Shopify’s blowout quarter as American consumers appeared, at least for now, to be undeterred by higher import prices due to inventory stockpiling and short-term discounting.

Earnings momentum was mixed elsewhere: Eli Lilly (LLY) surpassed second-quarter revenue estimates, propelled by surging demand for weight-loss and diabetes drugs, but disappointed on the results of a much-anticipated oral GLP-1 trial, sending the stock down as much as 14% at its lows. This underscores how markets remain especially sensitive to any news falling short of sky-high expectations.

Federal Reserve in Flux; Job Market Shows Strain

Financial markets were further stirred by the announcement that President Trump has nominated Stephen Miran, the current Chairman of the Council of Economic Advisors, to fill the vacancy on the Federal Reserve Board of Governors left by the resignation of Adriana Kugler. Miran, an academic economist with a Harvard Ph.D. and prior experience in the Trump administration, is expected to serve until January 2026, with a permanent replacement search ongoing. Separately, Bloomberg reported that Fed Governor Christopher Waller has emerged as a favorite to succeed Jerome Powell as Federal Reserve Chair, signaling possible changes ahead in monetary policy and market expectations.

Economic data continues to point toward a moderating labor market. The U.S. saw 1.974 million continuing unemployment claims filed at the end of July, the highest since late 2021. Initial jobless claims rose to 226,000, while earlier jobs reports for May and June were revised downward, compounding worries about the health of the economic recovery and raising bets the Fed could move to cut interest rates as soon as September. Gold responded in kind, climbing 0.6% to over $3,454 per ounce as investors sought safe-haven assets in anticipation of monetary easing and persistent inflation concerns stemming from the tariff regime.

IPOs, Crypto, and Headlines to Watch

Elsewhere, Firefly Aerospace (FLY) executed a blockbuster Nasdaq debut, opening 56% above its $45 IPO price as investor appetite for space and technology plays remains elevated. Meanwhile, the crypto sector rallied ahead of a presidential executive order that would allow Americans to include cryptocurrencies and private equity in retirement portfolios, with Bitcoin up 2%, ether up 4%, and XRP mirroring gains. Shares of Coinbase rose 3.4% as digital assets became more deeply embedded in U.S. capital markets.

Other notable stories included President Trump’s social media call for the resignation of Intel CEO Lip-Bu Tan after concerns about his ties to Chinese firms, and strong earnings reports from SoftBank and Warner Bros. Discovery. Meanwhile, investors kept a wary eye on mortgage rates, which dipped near 2025 lows following the weaker jobs data—an indicator of both economic softness and the potential for further Fed intervention.

Looking Ahead: Volatility Set to Continue

With trade tensions dominating headlines, corporate America scrambling to adjust, and central bank policy up in the air, market volatility is poised to persist. Investors will watch for further administration comments on tariff carveouts, developments in the ongoing Federal Reserve leadership transition, and fresh data on employment, production, and consumer demand for signals about the economy’s trajectory in the coming months. For now, the U.S. stock market finds itself at the crossroads of protectionist policy, technology-driven optimism, and mounting macroeconomic uncertainty—a recipe for swings that are likely to define the remainder of 2025.
