In Q4 2024, the U.S. stock market saw a remarkable $1.45 trillion surge in market capitalization, primarily driven by a handful of tech giants. The top contributors were Tesla, Amazon, Nvidia, Alphabet, Broadcom, and Apple, which collectively added $1.92 trillion to the market cap. However, the remaining S&P 500 companies experienced a combined loss of $0.58 trillion, highlighting the concentrated nature of the growth.
Interestingly, U.S. stocks outside the S&P 500 also saw modest gains, adding $0.11 trillion to their market cap. This dynamic underscore the dominance of tech companies in leading the market's overall performance while leaving broader sectors with mixed outcomes.
