Trader sentiment on S&P 500 single-day gains and losses in Q1 2026 reflects heightened volatility amid geopolitical tensions from the Iran conflict, surging oil prices, and the index's slide into correction territory, with the benchmark down over 8% from its February peak of around 6,932. The largest loss so far stands at -2.06% on January 20, triggered by policy concerns, while the top gain was +1.97% on February 6 amid brief relief rallies; recent sessions saw -1.74% on March 26 and -1.67% on March 27 as the index closed at 6,368.85 below key moving averages. With Q1 ending March 31, Federal Reserve Chair Powell's 10:30 a.m. speech and New York Fed President Williams' remarks today could catalyze outsized moves, alongside ongoing economic data scrutiny.

The percentage change in the S&P 500 Index (SPX) on a given trading day will be calculated by comparing the official closing price for the S&P 500 Index (SPX) on that day to the official closing price for the S&P 500 Index (SPX) on the previous trading day, as reported by the Wall Street Journal. The previous day’s closing price will be subtracted from the current day’s closing price, and then that difference will be divided by the previous day’s closing price. If the daily percentage change is negative, it will be considered a loss of that percentage in absolute terms.
Daily percentage changes will be rounded to two decimal places away from zero (e.g. a daily percentage loss of 1.995% would be considered 2.00%, and a daily percentage loss of 1.993% would be considered 1.99%)
If any relevant trading day is shortened (for example, due to a market-holiday schedule), the official closing price published for that shortened session will still be used for resolution.
If no official closing price is published for a relevant trading day (for example, due to a trading halt into the close, system issue, or other disruption), this market will use the most recent official price published by the specified resolution source as the effective closing price.
The resolution source for this market will be the Wall Street Journal, specifically the daily CLOSE prices for the S&P 500 Index (SPX) published on the S&P 500 Index (SPX) historical prices page (https://www.wsj.com/market-data/quotes/index/SPX/historical-prices).
