Wall Road’s comeback from tariff turmoil to hit a document excessive has dramatically narrowed the hole with European shares, testing the mettle of traders who have been betting on an finish to an period of exceptionalism for US markets.
The blue-chip S&P 500 inventory index has torn 10 per cent larger within the second quarter of the 12 months, far outstripping Europe’s region-wide Stoxx 600, which has risen much less 2 per cent, in addition to different large world indices.
The outperformance of American shares is confounding bets that US President Donald Trump’s chaotic tariff insurance policies would spark an enduring rotation into different markets, notably Europe, the place hopes of a spending splurge on defence and infrastructure buoyed shares early in 2025. As a substitute, traders have flooded again to the tech shares that had powered the market rally of latest years.
“Within the second quarter, what we’ve seen is a reversion to the playbook,” mentioned Shep Perkins, chief funding officer at fairness fund supervisor Putnam Investments.
European shares are nonetheless narrowly outperforming US friends in 2025, pushed by optimism that broad motion in the direction of fiscal stimulus and reforms to deliver the bloc’s economies nearer collectively will ignite progress. The region-wide Stoxx Europe 600 is 7 per cent larger in 2025, in contrast with 5 per cent for the S&P.
However Europe’s latest underperformance is feeding nervousness amongst traders that the area is failing to maintain the momentum created by Germany’s €1tn “no matter it takes” spending plan for defence and infrastructure.
“The European drawback has all the time been earnings, earnings, earnings,” mentioned Dec Mullarkey, managing director at fund supervisor SLC Administration. “You possibly can debate US valuations all you want, however these shares are backed by strong steadiness sheets. The Europe commerce is way extra speculative, it is determined by Germany, for instance, following by on its infrastructure plan.”
Optimism over Europe’s prospects is but to point out up meaningfully in financial knowledge. The European Fee final month revised down its progress forecasts after Trump’s tariff broadside. Shopper and enterprise sentiment for each the EU and euro space declined in June, based on a fee survey printed final week.
In the meantime, the US has had extra sturdy jobs numbers than anticipated, and unemployment is holding regular, regardless of predictions of a commerce warfare hit.
US shares have additionally been underpinned by each retail traders, who’ve piled into equities to “purchase the dip”, and by firms, which have guess on themselves by shopping for again their very own shares in document portions.

As Large Tech shares take the lead, a a lot predicted broadening in fairness returns has stalled. Another model of the S&P that equally weights constituents is trailing its conventional, market cap-weighted equal this 12 months.
Some traders are sticking to their expectations of a broader rotation away from US markets, as world traders query the massive chubby they’ve constructed up in greenback belongings.
Though equities have narrowed the efficiency hole within the second quarter, the greenback stays 13 per cent decrease towards the euro — that means there’s nonetheless a large gulf if returns are measured in the identical forex — and US Treasuries have come beneath stress amid considerations over the rising American debt load.
Goldman Sachs analysts mentioned in a notice final week that US inventory valuations had grow to be stretched, even adjusting for the higher return on fairness that US firms present. “The period of diversification has begun,” the analysts wrote. “We expect it has additional to run.”
Some traders assume turbulence on Wall Road might return as Trump continues to wage his commerce warfare. The president’s 90-day pause on so-called reciprocal tariffs expires early subsequent week and the US stays in negotiations with nations all over the world to avert the imposition of hefty commerce levies.
Over the long run, fading financial progress within the US in addition to Europe’s fiscal push ought to assist to slim the persistent transatlantic hole in inventory market efficiency, based on Luca Paolini, chief strategist at Pictet Asset Administration.
