Nvidia shares fell more than 10% early Thursday after chief executive Jensen Huang stepped down, before narrowing the decline to a little over 5% by the afternoon. Because of its market capitalization, Nvidia represents a significant holding in several funds, but average exposure remains limited across most mutual funds and exchange-traded funds. A 10% Nvidia decline would therefore reduce the Vanguard S&P 500 by about 0.84%, the Invesco QQQ by 0.68%, and the Vanguard Total Stock Market by 0.71%. The highest average weighting, 10.34%, is found in large-growth funds, while technology-sector funds have an average exposure of 7.31%. The shock could put greater pressure on semiconductor and artificial-intelligence-related stocks, although experts did not anticipate a lasting decline across the broader markets.
