STOXX 600 marginally higher, luxury and basic resources lead
The pan-European STOXX 600 index posted a marginal move on Wednesday morning, rising 0.06% to 656.87 points by 08:23 GMT according to Devdiscourse, or 0.1% to 657.34 points by 07:03 GMT according to Reuters, reflecting fluctuations during the European morning session. Investors adopted a wait-and-see stance ahead of a catalyst-packed day.
At the sector level, basic resources led the gains with a 0.9% advance, supported by falling commodity prices and hopes of geopolitical de-escalation. Luxury stocks gained 1.2%, lifted by renewed appetite for cyclical assets. Conversely, the technology sector declined 0.2% to 1.1% ahead of Nvidia’s earnings release, scheduled for later in the day.
Oil retreats as Hormuz reopening hopes grow
Brent crude futures fell for a third consecutive day, dropping more than 2% to settle around $86 a barrel. The move reflects expectations of increased oil flows through the Strait of Hormuz, a strategic chokepoint for roughly 20% of global oil trade.
Iran announced it had resumed negotiations with Oman over the management of the Strait of Hormuz, amid growing pressure from US President Donald Trump in the nearly six-month conflict that has roiled oil markets and fueled global inflation concerns, according to multiple sources. This geopolitical development also contributed to lower European bond yields.
The STOXX 600 energy index declined between 1.1% and 1.2%, making it the weakest sector on the index. Meanwhile, US Deputy Treasury Secretary Scott Bessent was scheduled to hold a press conference earlier in the week on Iran sanctions.
Nvidia: the decisive test for the tech sector
Investors are awaiting Nvidia’s second-quarter results, due later in the day, to determine whether the AI spending boom can continue to justify elevated market expectations, Reuters reported. Nvidia shares, which have significantly outperformed indices in 2025-2026, have become the bellwether for the AI sector.
Analysts polled by Devdiscourse expect Nvidia to forecast:
- 82.8% sales growth in the third quarter, to $104.20 billion
- An adjusted gross margin for Q2 and Q3 around 75%
« We have a lot of risks ahead and, although European markets are not directly impacted by Nvidia’s earnings or Kevin Warsh’s speech, they will be indirectly. »

Among single stocks, SAP fell 4.2% and was the biggest drag on the STOXX 600 after US software maker Intuit released disappointing guidance. UBS downgraded the German software group to « neutral », adding to selling pressure. Shell slipped 0.1% after the Financial Times reported that Exxon Mobil had shown interest in the company’s US chemicals assets.
Asia retreats: Nikkei and chip stocks under pressure
In Asia, Japanese markets opened lower ahead of Nvidia’s release. The Nikkei index fell to 65,595.13 points, down 0.4%, dragged down by semiconductor and electronics-related stocks.
| Index / Stock | Change | Level |
|---|---|---|
| STOXX 600 | +0.06% | 656.87 |
| Basic Resources | +0.9% | — |
| Luxury | +1.2% | — |
| Energy | -1.1% to -1.2% | — |
| Technology | -0.2% to -1.1% | — |
| SAP | -4.2% | — |
| Nikkei 225 | -0.4% | 65,595.13 |
| Kioxia Holdings | -1.0% | — |
| Tokyo Electron | -1.9% | — |
According to the Wall Street Journal, Kioxia Holdings dropped 1.0% and Tokyo Electron lost 1.9%, as investors preferred to reduce their exposure to semiconductors ahead of Nvidia’s verdict.
Looking ahead: Jackson Hole and the ECB
Attention is also turning to a key US inflation report due later in the day and to a speech by Federal Reserve Chair Kevin Warsh at the Jackson Hole symposium on Friday. Investors are seeking clues on the trajectory of US interest rates in an environment shaped by inflationary pressures linked to the Iran conflict.
In Europe, European Central Bank (ECB) policymakers are poised to raise interest rates by another 25 basis points at the September meeting to counter the economic effects of the Iran war, although they are reluctant to signal further tightening beyond that date, according to three sources cited by Reuters. On Monday, August 24, the STOXX 50 had fallen 0.2% to 6,450 and the STOXX 600 had slipped 0.1%, as investors turned cautious ahead of a busy week.
Conclusion
The trading session of August 26, 2026, perfectly illustrates the crossroads of uncertainty facing European markets. The triple wait for Nvidia’s results, the Jackson Hole symposium, and the US inflation report represents a major test for investor confidence, already shaken by six months of Middle East conflict. The pullback in oil to $86 provides temporary support, but the prospect of an ECB rate hike in September limits the rebound margin for European equities.
Two scenarios now dominate: a Nvidia release in line with expectations of $104.20 billion in Q3 revenue would reignite sector rotation into tech, while a hawkish signal from Kevin Warsh at Jackson Hole would reinforce pressure on European cyclical stocks. The luxury and basic resources sectors could remain the main beneficiaries of any geopolitical easing, while energy will continue to react to developments in the Iran file.
