description: "科技公司的盈利大幅增長，第一季度的盈利同比增長超過 50%，而前瞻市盈率從去年的 30 多降至 23.6。然而，頂尖科技公司現在佔美國可投資資產的 40% 以上，這一集中度讓人想起 2000 年的泡沫。七大巨頭的表現也凸顯了投資組合多樣化的重要性，2022 年它們的跌幅為 40%，而標準普爾指數的跌幅為 18%"

# 科技公司盈利大幅增長，而集中風險已接近 2000 年的水平

Earnings beat valuations: Tech’s forward P/E has fallen to 23.6 from over 30 last year, even as Q1 earnings grew more than 50% year-over-year. Concentration at extremes: Top tech names now comprise over 40% of U.S. investable assets, a level not seen since the 2000 bubble. Portfolio risk lessons: In 2022, the Magnificent Seven fell 40% versus the S&P’s 18%, underscoring the need for diversification.
