Market Rally: Wall Street Ends Higher as Supreme Court Limits Tariff Authority

Stocks closed higher Friday after the Supreme Court ruled that former President Trump’s broad tariff measures were unlawful. The decision curtailed the executive branch’s authority to impose tariffs under the International Emergency Economic Powers Act, offering investors a measure of clarity on trade policy and easing concerns around escalating protectionism.

The rebound comes against a backdrop of shifting capital flows. In the months leading up to February 2026, investors had been pulling money from U.S. equities, with roughly $75 billion withdrawn over a six-month period, including more than $50 billion in the first two months of the year alone, as some funds rotated into overseas markets. Reuters described the trend as a mounting “Wall Street exodus,” reflecting unease around trade policy, fiscal uncertainty, and relative global valuations.

Key Takeaways

• The U.S. Supreme Court struck down Trump’s broad tariff regime imposed under emergency powers.

• Major U.S. stock indexes finished higher following the ruling.

• Recent capital outflows from U.S. equities highlight that investor sentiment had already been fragile.

Judicial Clarity Amid Capital Rotation

The Court’s decision effectively dismantled a major portion of the administration’s tariff framework, signaling limits on unilateral trade actions. While not all tariffs are affected, the ruling reduces uncertainty tied to executive trade authority.

Major benchmarks including the S&P 500, Nasdaq, and Dow Jones Industrial Average closed in positive territory, with technology and consumer discretionary sectors among those benefiting from the relief move.

However, the rally should be viewed in context. Recent months have seen capital rotating away from U.S. equities toward international markets, as investors reassessed growth prospects and policy risks. The Supreme Court’s intervention may slow that narrative, but broader macro drivers, interest rates, earnings growth, and global risk appetite, remain central to market direction.
