The iShares Core S&P 500 ETF (IVV) gained 1.13% on September 18, 2026, closing at $764.10. The move extended a modest positive run over the near term, with the fund also up 0.34% over the trailing seven-day period.
Despite the daily and weekly advances, IVV remained in negative territory on a 30-day basis, sitting 0.89% below where it traded one month ago. That broader pullback reflects the modest pressure the fund has faced over a longer window even as shorter-term momentum has turned positive.
IVV is designed to track the S&P 500 index, providing broad exposure to large-cap U.S. equities. The fund's price movements closely mirror the overall direction of that benchmark, making its performance a widely watched indicator of broad U.S. equity market conditions.
