Barclays Sees Further Upside for Equities Despite Signs of Excess in AI-Driven Rally

Barclays believes global equities can continue advancing even as enthusiasm surrounding artificial intelligence and semiconductor stocks pushes parts of the market into increasingly crowded territory. According to the bank, resilient corporate earnings and abundant market liquidity remain key supports for the ongoing bull market.

The bank’s European equity strategists acknowledge that valuations in certain areas appear elevated, but argue that the broader backdrop for stocks remains constructive. While global equity indices have reached record levels, Barclays notes that gains have been concentrated primarily in semiconductor-related shares, with many other sectors trailing the rally.

Crowded Positioning Raises the Risk of Short-Term Volatility

The strategists highlighted several factors that could justify a more defensive stance in the near term. Positioning among hedge funds and commodity trading advisors (CTAs) in AI-linked and momentum stocks appears increasingly stretched, while declining oil inventories and rising bond yields are creating additional risks.

Strategists led by Emmanuel Cau noted that yields are approaching “the danger zone,” a development that could test investor confidence if borrowing costs continue to rise.

The team also pointed to a busy IPO calendar and historically weak summer trading patterns as potential catalysts for profit-taking in some of the market’s most crowded trades.

Inflation Pressures Complicate the Growth Outlook

Barclays cautioned that the balance between economic growth and policy support is becoming less favorable as inflation begins to re-emerge.

The resurgence in price pressures has revived discussions around further interest rate increases, although the bank does not expect the Federal Reserve to act aggressively in the near future.

Despite these challenges, Barclays remains constructive on equities and sees opportunities for broader market participation if macroeconomic conditions improve.

Peace Scenario Could Spark Rotation Into Lagging Markets

The bank argues that an improvement in geopolitical conditions could trigger a wider market rally.

Barclays views a potential U.S.-Iran peace agreement as increasingly likely and believes such an outcome could lower oil prices, ease inflation concerns and spark a rally in government bonds. A decline in yields could, in turn, support sectors and regions that have underperformed since the conflict began, including European equities and consumer-focused stocks.

Under this scenario, the bank established a STOXX 600 “peace target” of 670.

“Trump’s need for an off-ramp means de-escalation bias may still prevail and provide a floor to equities,” the strategists say.

Strong Earnings Continue to Support the Bull Case

On the corporate side, Barclays raised its forecast for European earnings growth in 2026 to 10%.

The bank cited stronger-than-average nominal economic growth and supportive energy prices as factors likely to boost headline earnings. Significant upward revisions in the energy and semiconductor sectors are expected to offset more modest downgrades elsewhere in the market.

“Earnings resilience remains the key anchor of the bull market,” the strategists continued.

Equities Still Favored Over Bonds

Although equity valuations remain above historical averages, Barclays notes that multiples have moderated since the start of the year.

The bank argues that rising inflation expectations and ongoing fiscal pressures continue to make stocks more attractive than fixed-income investments.

Share buybacks are also expected to provide ongoing support. Barclays estimates that roughly two-thirds of announced European repurchase programs for 2026 have yet to be executed, leaving substantial room for additional demand from corporate buyers.

Regional Preferences Remain Unchanged

Barclays maintained its preference for U.S. equities over European markets while also retaining overweight positions in emerging markets and Japan.

The bank sees Japan as a particularly attractive beneficiary of the long-term artificial intelligence investment cycle and the continued strength of memory-chip demand, themes that it expects to remain important drivers of market performance in the years ahead.
