The Shift of June 26

Global markets on Friday June 26, 2026 are crystallising a phenomenon that has been developing in the background for several weeks: the great geographical rotation between the United States and Europe. On one side, European indices post significant gains — DAX at +1.59%, CAC 40 at +1.40% — driven by geopolitical de-escalation in the Middle East and inflation data that is proving less persistent than its American counterpart. On the other, Wall Street records a fourth consecutive session of declines, weighed down by a repricing of technology megacaps.

This is not a simple technical correction. It is the market beginning to integrate a more nuanced reality: US tech valuations — built on assumptions of low rates and rapid inflation decline — must readjust to an environment where Fed Chair Kevin Warsh maintains rates at 3.50-3.75% and signals no cuts before end-2026. Meanwhile, Europe benefits from a dual catalyst: the normalisation of oil prices and confirmation that the ECB, following its June 11 hike (+25bp, deposit rate at 2.25%), appears to have reached what looks like its cycle peak.

Bayer perfectly illustrates this European dynamic: the stock surges +18.72% after the US Supreme Court ruled in its favour in the Roundup litigation, lifting a legal cloud that has weighed on the group’s valuation for years. This type of idiosyncratic event — specific to a single company, disconnected from the macro cycle — is precisely what one seeks during a rotation phase: catalysts indifferent to US interest rates.

The June 26 Market Dashboard

The numbers speak for themselves. In a single session, the performance gap between Europe and US megacaps exceeds 7 percentage points. Apple suffers its sharpest decline in months, following an announcement of price increases on its hardware products — a direct consequence of additional costs imposed by tariffs on Asian components. Microsoft falls 3.5% for similar reasons. Only Micron (+15.7%) outperforms, driven by quarterly results and guidance for memory that exceeded expectations — confirming that artificial intelligence creates highly selective winners within the tech sector.

PCE at 4.1%: The Inflation Reading That Changes Everything

The data published yesterday — Thursday June 25 — is what is structuring market sentiment this Friday. The PCE (Personal Consumption Expenditures) index, the Fed’s reference measure for inflation, came in at 4.1% year-on-year for May 2026. This is the highest level since April 2023, exceeding consensus expectations of 3.8%. Core PCE (excluding food and energy), even more closely watched by central bankers, prints at 3.4% — the highest since October 2023.

These figures have two immediate implications. First: Warsh’s Fed cannot cut rates. Second, more insidiously: technology stock valuations — built on assumptions of a rapid return of inflation to 2% — must be revised downward. A stock trading at 35x earnings with a risk-free rate of 3.5-4% offers a negative equity risk premium. Institutional investors know this, and they are acting accordingly.

For Europe, the same inflationary dynamic does not apply with the same intensity. The fall in oil from $113 to $76/barrel WTI — a direct consequence of diplomatic negotiations between Washington and Tehran over the Hormuz crisis — mechanically reduces pressure on eurozone consumer prices. The market anticipates that the ECB, following its last hike on June 11, is entering a pause phase. European rates have less room to rise. European valuations, historically lower than their US counterparts, thus become attractive in relative terms.

Three Concrete Allocation Adjustments

In this rotation environment, three portfolio moves appear warranted at the margin for a balanced risk profile. These adjustments are not a radical overhaul of allocation, but a pragmatic recalibration reflecting current market signals.

Risks Not to Underestimate

The geographical rotation is an attractive move on paper, but it carries its own pitfalls. Three risks deserve your attention before making allocation switches.

First risk: an oil rebound. The de-escalation in the Strait of Hormuz is fragile. A renewed flare-up in US-Iran tensions or a fresh escalation in the region could push Brent back rapidly toward $90-100/barrel. In this scenario, Europe’s competitive advantage over the United States evaporates, and European inflation reaccelerates, forcing the ECB into a further tightening move.

Second risk: European recession. Germany has shown abnormally low growth since 2024. Industrial PMI data remains in contraction territory in several eurozone countries. Overweighting European value in cyclical names exposes your portfolio to a significant drawdown if growth disappoints.

Third risk: tech is not dead. Corrections of 5-10% in US megacaps have historically been attractive entry points for long-term investors. Micron’s +15.7% gain today illustrates that positive catalysts still exist within the sector. A complete exit from US tech would be an allocation error as much as a timing mistake.

The key is nuance: the goal is not to shift your entire portfolio from one geography to another, but to make marginal adjustments that reflect the new macro environment without compromising global diversification. A well-structured portfolio is one that captures these rotations without becoming dependent on them.
