Nvidia has emerged as a significant driver of market performance in 2024, contributing 5.2 percentage points to the S&P 500's overall 22% gain this year. Without Nvidia, the index would have only increased by 16.6%. The company has offset losses from all 128 S&P 500 companies that have declined this year, effectively doubling its impact. Nvidia's stock has surged nearly 190% year-to-date, fueled by a boom in generative AI and resulting in a series of positive forecasts. Since October 7, Nvidia has accounted for 75% of the gains in the Bloomberg 500, a proxy for the S&P 500, and without its performance, the index would have remained flat. Nvidia's year-to-date return stands at 147%, significantly outperforming other major stocks in the market, and its next earnings report is anticipated in the coming weeks.
