Según informes de Jinshi, impulsados por el sentimiento optimista hacia la IA y sólidos informes de ganancias, tanto el índice S&P 500 como el Nasdaq han alcanzado máximos históricos. Sin embargo, esta ronda de aumentos carece claramente de amplitud, ya que la mayor parte de las ganancias provienen principalmente de grandes valores tecnológicos. Los analistas de UBS señalaron que, en las seis semanas previas al 15 de mayo, la ventaja del índice S&P 500 ponderado por capitalización bursátil sobre el índice S&P 500 de igual ponderación alcanzó el margen más amplio en al menos 35 años. UBS recomienda a los inversores reducir las posiciones excesivamente concentradas y protegerse contra el riesgo de concentración.
