Artificial intelligence enthusiasm is delivering momentum investors their strongest performance in decades, as technology shares continue climbing despite mounting geopolitical uncertainty. The rally extends beyond traditional tech names, lifting a broad array of AI-driven stocks that have become the market's primary growth engine.

This surge represents a significant shift in market leadership, with momentum strategies outperforming as investors pile into companies positioned to benefit from AI adoption. While defense and energy sectors typically gain during conflict periods, the persistent upward trajectory of technology shares signals that AI remains the dominant investment theme.

The disconnect between geopolitical tensions and stock performance highlights how the AI boom has become largely detached from traditional risk sentiment. Investors are focusing on long-term structural changes rather than near-term disruption concerns.

For portfolio managers, this environment validates positioning in secular growth themes, though the concentration risk in a handful of mega-cap names warrants attention as valuations expand.
