The iShares Core S&P 500 ETF (IVV) fell 1.10% on Sunday, October 17, 2026, settling at $766.7 as selling pressure weighed on the broad-market fund for a second consecutive session of notable decline.
Over the trailing seven days, IVV has lost 1.95%, reflecting a sustained period of weakness that has eroded gains accumulated earlier in the month. The daily move deepened an already negative weekly trend, suggesting broad pressure across the S&P 500 index constituents the fund tracks.
Despite the recent softness, the 30-day picture offers a measure of context: IVV is still up 1.47% over that window, indicating that the fund had built a cushion of gains before the current pullback began.
Market capitalization data was not available for IVV at the time of this report. The fund continues to serve as a widely followed benchmark vehicle for U.S. large-cap equity exposure.
