In 2026, U.S. and European equity markets are charting different courses. In the U.S., AI-driven growth and risk-on dynamics are dominant. The Volatility factor surged by about 30% in 2025, while Yield lagged, dropping roughly 12%.

Barclays attributes this to the Federal Reserve’s rate-cutting cycle and reduced tariff uncertainty, fostering a risk-positive environment. Growth outperformed due to AI-driven capital expenditure, while Value struggled in a moderating growth setting. Barclays maintains a positive outlook on U.S. Growth, citing a supportive interest rate environment and ongoing AI investments.

They are less optimistic about Value, arguing that modest demand and an easing cycle favor long-duration assets, limiting a sustained Value rotation. Momentum has been upgraded to positive due to strong margin expansion and stable equity volatility. Quality remains neutral, with few catalysts in a risk-taking market. In Europe, the story is different. Value and Momentum led in 2025, while Growth and Quality saw substantial losses. Barclays notes that Quality’s performance was its worst in two decades, driven by a shift toward value and cyclical sectors.

Looking ahead, Barclays is positive on European Value and Small Caps, supported by improving economic indicators and valuation discounts. Yield is seen as neutral, with enhanced income appeal under higher rates, despite weak earnings momentum. This divergence matters as it reflects broader economic and policy differences between the U.S. and Europe. Investors must consider these distinct factor dynamics when allocating capital across regions.
