Since late March, a wave of artificial intelligence optimism has lifted the Nasdaq 100 by thirty-three percent, drawing investors into technology stocks with a uniformity that strategists at Citigroup now regard as its own kind of danger. When belief becomes consensus and consensus becomes crowding, markets lose their capacity to absorb surprise.

Concentration of capital in US technology sector reinforces American financial market dominance but creates systemic vulnerability. European markets show weaker conviction (Euro Stoxx 50 moderately bearish), potentially widening transatlantic economic divergence if US correction occurs.
Similar to dot-com bubble (1999-2000) where concentrated enthusiasm in single sector preceded sharp reversals; also echoes 2021 meme stock dynamics where positioning extremes preceded volatility.
