Stoxx 600 leapt then cooled.

Big swings, quick reset

European shares posted a dramatic rebound on Thursday, only to see the mood turn cautious again as markets processed cross-border policy moves and the prospect of fresh corporate results. The regional Stoxx 600 jumped 3.7% on the day — its strongest session in three years — yet the backdrop remained jittery after a prior session that left the index down 3.5% at its lowest close since January 2024.

Volatility has been hard to miss; markets are bouncing around day-to-day, not trending steadily — the Stoxx 600 swung from a low close to a 3.7% jump in two sessions. Banking, industrials and technology led Thursday's gains with oversized moves — banks climbed about 5.15%, industrials roughly 4.9% and tech near 4.5% — dragging many laggards along for the ride.

Tariff headline drove the lift

The rally followed a sudden U.S. tariff U-turn — Trump cut many new rates to 10% for 90 days — and markets priced that in immediately. U.S. President Donald Trump temporarily scaled back new tariff rates on imports from most trade partners to 10% for 90 days. That reversal came after earlier comments that duties would remain in place.

CNBC reporters Dan Mangan and Sean Colon described the move as a market-friendly pivot — one that sparked a global risk-on reaction. U.S. Equities surged in response: the S&P 500 rallied more than 9% in Wednesday's session, marking one of its largest one-day gains since World War II. But gains in New York cooled quickly; by Thursday U.S. Indexes had returned to the red as growth worries re-emerged.

What the tariff shuffle actually meant

The tariff picture was messy: most partners got a temporary pause while China faced higher effective duties. China didn't get the same break — the White House increased duties on the country after Beijing announced stepped-up tariffs on U.S. Imports.

A CNBC report noted the headline rate on China effectively totals 145% when a previously announced 20% fentanyl-related duty is included.

The European Union moved in parallel. EU lawmakers had earlier approved countermeasures after U.S. Steel and aluminium duties. But in reaction to the U.S. Pause, the bloc said it would put those counter-tariffs on hold for 90 days. And that pause helped ease a geopolitical source of risk that had been pressing on markets.

Mastheads

Currency and bond moves added to the picture

Global funding flows shifted along with the tariff headlines. The euro jumped about 2.16% against the U.S. Dollar to trade near $1.119 — its strongest level in seven months. Meanwhile, a recent sell-off in U.S. Treasuries halted, offering some relief to rate-sensitive assets.

A softer dollar, a stronger euro and steadier Treasuries changed the math for exporters and banks; the euro jumped about 2.16% to $1.119. Exporters watch currency swings closely. And banks, which outperformed on Thursday, are sensitive to the yield curve and funding conditions. So when bond market stress eased, some of the pressure that had been pressing down on financials loosened.

Earnings season adds a new test

Headlines flip fast; the tariff news lifted risk appetite one day and left traders cautious the next. The big tariff-driven move gave markets an immediate narrative. But corporate earnings are a recurring, fundamental test of whether equity gains stick.

Earnings reports will reset expectations — beats can widen rallies, misses can trigger sell-offs — that's why investors will watch results closely this season. When profits beat and guidance is lifted, investment flows can widen a rally. The opposite happens when firms miss or cut forecasts — volatility spikes and risk appetites pull back. After a week marked by big one-day gains and deep drops, earnings season is likely to be the next real litmus test for whether the recent bounce turns into a sustainable upswing.

Sector focus — who’s vulnerable, who benefits

Banks rallied hard on Thursday, helped by the calmer fixed-income backdrop and the tariff de-escalation that reduced some political risk. Industrials and technology also led the gains — sectors that often react to macro headlines and growth expectations.

Export-heavy firms will keep an eye on the euro. A near seven-month high for the currency makes overseas sales less valuable in euro terms.

Energy and materials names will also be sensitive to the shifting trade picture and to any follow-up policy steps from trading partners.

What investors are likely to watch next

Right now, the flow of market-moving items is straightforward: geopolitics, macro data and corporate earnings. Traders will parse company-by-company reports for signs that revenues and margins can withstand higher rates, volatile demand and currency moves.

Asia-Pacific markets reacted positively to the tariff reversal, with Japanese stocks among the leaders in the region on Thursday. That global lift shows how closely interconnected markets are — a policy tweak in Washington feeds into equity and currency moves from Tokyo to Frankfurt.

Risk remains — and that matters

So yes, Thursday's bounce was big. But the week has shown how quickly sentiment can swing. Rapid one-day rallies that follow policy headlines often meet a reality check when earnings and growth data arrive. Investors who chased the immediate bounce will be watching corporate reports for confirmation that profits and demand justify higher prices.

Markets look split: some traders are chasing headlines, others are worrying about slowing growth, and that division explains the sharp intraday swings. When one side wins out, we get days like Thursday. When the other wins, you get sharp reversals. Expect earnings to be the battleground for that argument over the next stretch.
