Theo báo cáo từ Jinshi, nhờ tâm lý lạc quan đối với AI và các báo cáo thu nhập khả quan, cả chỉ số S&P 500 và Nasdaq đều đã đạt mức cao kỷ lục. Tuy nhiên, đợt tăng giá này rõ ràng thiếu sự lan tỏa, khi phần lớn lợi nhuận chủ yếu đến từ các cổ phiếu công nghệ lớn. Các nhà phân tích của UBS chỉ ra rằng trong sáu tuần kết thúc vào ngày 15 tháng 5, khoảng cách dẫn trước của chỉ số S&P 500 trọng số vốn hóa thị trường so với chỉ số S&P 500 trọng số ngang đã đạt mức lớn nhất trong ít nhất 35 năm qua. UBS khuyến nghị các nhà đầu tư nên giảm bớt các vị thế quá tập trung và đề phòng rủi ro tập trung.
