Nasdaq Composite Reaction: Tech Stocks Tumble on Trade Fears
NEW YORK, United States – The Nasdaq Composite dropped more than 1% in early trading Monday as President Donald Trump escalated a new round of global tariffs to 15%, sparking fresh uncertainty just days after the Supreme Court struck down his broader tariff regime. On February 23, 2026, the tech-heavy index fell amid fears that higher import duties will raise costs for U.S. companies, slow global growth and trigger retaliation from trading partners.
Fast Facts
- Nasdaq Composite down 1.2% or roughly 271 points to approximately 22,615 in morning trade
- Dow Jones Industrial Average loses more than 690 points, or 1.4%
- Trump hikes temporary global tariff to 15% under Section 122 of the Trade Act of 1974
- Markets had rallied Friday after Supreme Court 6-3 ruling against prior IEEPA tariffs
Markets opened lower after Trump’s weekend announcement, with the Nasdaq Composite bearing the brunt of selling in technology and consumer discretionary shares sensitive to international supply chains. The move comes after Friday’s relief rally when the Supreme Court ruled that the International Emergency Economic Powers Act does not authorize presidential tariffs.
This latest twist in U.S. trade policy matters now because the Nasdaq Composite — which tracks more than 3,000 stocks and is dominated by technology and growth names — has powered much of the market’s gains since the 2023 bull market began. Renewed tariff fears threaten to disrupt the very sectors that drove the index to record highs in 2025, from semiconductors to cloud computing.
Market Reaction
Trading volume surged as investors repriced risk. Heavyweight technology stocks led declines, with Amazon.com and Tesla each falling around 2% early Monday. The information technology sector within the broader market dropped 0.3%, while software and services names slid nearly 3%.
The Nasdaq Composite’s slide follows a strong Friday close at 22,886.07, up 0.9% and 1.51% for the week. That gain came on the Supreme Court’s decision limiting executive tariff power. By Monday, the narrative flipped. Trump, responding to the ruling, first announced a 10% global tariff late Friday and hiked it to 15% on Saturday via Truth Social, warning that countries “playing games” would face even higher rates.
“Any Country that wants to ‘play games’ with the ridiculous supreme court decision… will be met with a much higher Tariff,” Trump posted. The statement injected immediate volatility back into equity futures.
Official Statements
White House officials described the new tariffs as temporary under existing trade law, designed to pressure trading partners on issues from drug trafficking to trade deficits. European Commission spokespeople pushed back Sunday, saying “a deal is a deal” and rejecting any increase. U.S. Trade Representative Jamieson Greer reiterated that existing trade agreements remain intact.
Wall Street analysts offered measured views. “The market is just experiencing some profit-taking as traders realize that the relief rally from Friday may be premature,” said Thomas Hayes, chairman at Great Hill Capital LLC. “You simply can’t bet against Trump. He wants tariffs, and he’s going to find a way to implement them.”
Michael Landsberg, chief investment officer at Landsberg Bennett Private Wealth Management, added: “The big question for the economy is what happens after this window, and if the tariff policy stays down this path, we may very well be back at the Supreme Court later this year.”
Tech Sector Hit Hardest
The Nasdaq Composite’s composition explains its outsized reaction. Technology stocks account for more than 40% of the index’s weight, with the “Magnificent Seven” alone representing a substantial portion. Companies like Nvidia, Apple, Microsoft and Amazon rely on global supply chains, particularly in Asia. Higher tariffs raise input costs, squeeze margins and risk slower demand if trading partners retaliate.
Semiconductor names felt immediate pressure. Any escalation in duties on Chinese imports could disrupt the flow of chips and components critical to AI infrastructure. Consumer electronics and e-commerce giants face similar headwinds from elevated shipping and component prices passed on to U.S. buyers.
Legal Background of the Tariff Battle
The Supreme Court’s Feb. 20, 2026, 6-3 ruling in Learning Resources, Inc. v. Trump and the companion Trump v. V.O.S. Selections marked a significant check on executive power. Chief Justice John Roberts wrote that the International Emergency Economic Powers Act does not grant authority to impose tariffs, emphasizing that the Constitution reserves the power to lay duties and imposts to Congress.
The decision invalidated the broad “reciprocal” and drug-trafficking tariffs imposed via executive orders in 2025. Those measures had included 25% duties on most Canadian and Mexican imports, 10% on Chinese goods, and universal duties on all trading partners to address trade deficits.
While the ruling delivered a legal victory for importers and businesses that challenged the tariffs, it left open the question of refunds for more than $130 billion already collected. The Court vacated one lower-court judgment on jurisdictional grounds and affirmed the other on the merits.
Trump immediately pivoted to Section 122 of the Trade Act of 1974, which allows the president to impose temporary tariffs of up to 15% for 150 days to address balance-of-payments issues. That statute requires congressional approval to extend beyond the initial period.
Historical Context and Timeline
ariff policy has long influenced U.S. equity markets, and the Nasdaq Composite has proven especially sensitive because of its growth tilt.
During the 2018-2019 U.S.-China trade war, the Nasdaq Composite fell more than 20% at its worst point before recovering on phase-one deal hopes.
The index’s recovery in 2020-2021 was fueled by low rates and pandemic-driven tech demand. The 2022 bear market saw the Nasdaq Composite drop nearly 33% amid inflation and rate hikes.
The subsequent bull run from April 2025 onward added more than 54% by early 2026, powered by artificial intelligence investment.
The latest episode echoes that volatility but occurs against a backdrop of already elevated valuations. The index sits well above its 200-day moving average, leaving less cushion if policy uncertainty persists.
Economic Implications
Economists warn that even temporary tariffs can raise consumer prices and slow growth. Goldman Sachs estimates U.S. consumers absorb 55% of tariff costs, with businesses taking another 22%. Yale Budget Lab projects a 1.2% rise in consumer prices in 2026 from tariffs alone and a 0.4 percentage-point drag on real GDP, plus a 0.6 percentage-point rise in unemployment.
For the Nasdaq Composite, the transmission mechanism is direct: higher costs for imported components compress corporate margins, while retaliation risks slower export demand for U.S. technology and services.
Retail investors, many of whom hold Nasdaq-heavy index funds or tech ETFs in retirement accounts, face renewed portfolio pressure. The index’s year-to-date performance in 2026 had been positive but modest compared with 2025’s double-digit gains.
Global Reactions and India Angle
International markets reflected the uncertainty. Asian indexes opened mixed Monday, with South Korea’s Kospi touching records on domestic factors but Hong Kong’s Hang Seng gaining on hopes of stimulus. European futures pointed lower.
For Indian readers and global investors with exposure to emerging markets, the story carries extra weight. India’s IT services and pharmaceutical sectors, which export heavily to the U.S., could face indirect pressure if American companies cut spending amid higher costs. Conversely, some Indian manufacturers may benefit if U.S. firms seek alternative suppliers outside China.
What’s Next
Markets now await several catalysts. Nvidia is scheduled to report fiscal fourth-quarter results on Feb. 25, 2026 — a key test for the AI trade that has underpinned much of the Nasdaq Composite’s recent strength.
The Federal Reserve’s next policy meeting looms, with officials likely to weigh tariff-driven inflation risks against growth concerns. Congressional Democrats and some Republicans have signaled willingness to challenge the new tariffs under Section 122 if they are extended.
